§ 658.1 Purpose.
top
The purpose of this part is to identify a National Network of highways available to vehicles authorized by provisions of the Surface Transportation Assistance Act of 1982 (STAA) as amended, and to prescribe national policies that govern truck and bus size and weight.
[59 FR 30419, June 13, 1994]
§ 658.3 Policy statement.
top
The Federal Highway Administration's (FHWA) policy is to provide a safe and efficient National Network of highways that can safely and efficiently accommodate the large vehicles authorized by the STAA. This network includes the Interstate System plus other qualifying Federal-aid Primary System Highways.
§ 658.5 Definitions.
top
Automobile transporters. Any vehicle combination designed and used specifically for the transport of assembled highway vehicles, including truck camper units.
Beverage semitrailer. A van-type, drop-frame semitrailer designed and used specifically for the transport and delivery of bottled or canned beverages (i.e., liquids for drinking, including water) which has side-only access for loading and unloading this commodity. Semitrailer has the same meaning as in 49 CFR 390.5.
Boat transporters. Any vehicle combination designed and used specifically to transport assembled boats and boat hulls. Boats may be partially disassembled to facilitate transporting.
Bridge gross weight formula. The standard specifying the relationship between axle (or groups of axles) spacing and the gross weight that (those) axle(s) may carry expressed by the formula:
where W=overall gross weight on any group of two or more consecutive axles to the nearest 500 pounds, L=distance in feet between the extreme of any group of two or more consecutive axles, and N=number of axles in the group under consideration.
Cargo-carrying unit. As used in this part, cargo-carrying unit means any portion of a commercial motor vehicle (CMV) combination (other than a truck tractor) used for the carrying of cargo, including a trailer, semitrailer, or the cargo-carrying section of a single-unit truck. The length of the cargo carrying units of a CMV with two or more such units is measured from the front of the first unit to the rear of the last [including the hitch(es) between the units].
Commercial motor vehicle. For purposes of this regulation, a motor vehicle designed or regularly used to carry freight, merchandise, or more than ten passengers, whether loaded or empty, including buses, but not including vehicles used for vanpools, or vehicles built and operated as recreational vehicles.
Dromedary unit. A box, deck, or plate mounted behind the cab and forward of the fifth wheel on the frame of the power unit of a truck tractor-semitrailer combination.
Federal-aid Primary System. The Federal-aid Highway System of rural arterials and their extensions into or through urban areas in existence on June 1, 1991, as described in 23 U.S.C. 103(b) in effect at that time.
Fullmount. A fullmount is a smaller vehicle mounted completely on the frame of either the first or last vehicle in a saddlemount combination.
Interstate System. The National System of Interstate and Defense Highways described in sections 103(e) and 139(a) of Title 23, U.S.C. For the purpose of this regulation this system includes toll roads designated as Interstate.
Length exclusive devices. Devices excluded from the measurement of vehicle length. Such devices shall not be designed or used to carry cargo.
Longer combination vehicle (LCV). As used in this part, longer combination vehicle means any combination of a truck tractor and two or more trailers or semitrailers which operates on the Interstate System at a gross vehicle weight greater than 80,000 pounds.
Maxi-cube vehicle. A maxi-cube vehicle is a combination vehicle consisting of a power unit and a trailing unit, both of which are designed to carry cargo. The power unit is a nonarticulated truck with one or more drive axles that carries either a detachable or a permanently attached cargo box. The trailing unit is a trailer or semitrailer with a cargo box so designed that the power unit may be loaded and unloaded through the trailing unit. Neither cargo box shall exceed 34 feet in length, excluding drawbar or hitching device; the distance from the front of the first to the rear of the second cargo box shall not exceed 60 feet, including the space between the cargo boxes; and the overall length of the combination vehicle shall not exceed 65 feet, including the space between the cargo boxes.
Motor carrier of passengers. As used in this part, a motor carrier of passengers is a common, contract, or private carrier using a bus to provide commercial transportation of passengers. Bus has the same meaning as in 49 CFR 390.5.
National Network (NN). The composite of the individual network of highways from each State on which vehicles authorized by the provisions of the STAA are allowed to operate. The network in each State includes the Interstate System, exclusive of those portions excepted under §658.11(f) or deleted under §658.11(d), and those portions of the Federal-aid Primary System in existence on June 1, 1991, set out by the FHWA in appendix A to this part.
Nondivisible load or vehicle.
(1) As used in this part, nondivisible means any load or vehicle exceeding applicable length or weight limits which, if separated into smaller loads or vehicles, would:
(i) Compromise the intended use of the vehicle, i.e., make it unable to perform the function for which it was intended;
(ii) Destroy the value of the load or vehicle, i.e., make it unusable for its intended purpose; or
(iii) Require more than 8 workhours to dismantle using appropriate equipment. The applicant for a nondivisible load permit has the burden of proof as to the number of workhours required to dismantle the load.
(2) A State may treat emergency response vehicles, casks designed for the transport of spent nuclear materials, and military vehicles transporting marked military equipment or materiel as nondivisible vehicles or loads.
Saddlemount combination. A saddlemount combination is a combination of vehicles in which a truck or truck tractor tows one or more trucks or truck tractors, each connected by a saddle to the frame or fifth wheel of the vehicle in front of it. The saddle is a mechanism that connects the front axle of the towed vehicle to the frame or fifth wheel of the vehicle in front and functions like a fifth wheel kingpin connection. When two vehicles are towed in this manner the combination is called a double saddlemount combination. When three vehicles are towed in this manner, the combination is called a triple saddlemount combination.
Single axle weight. The total weight transmitted to the road by all wheels whose centers may be included between two parallel transverse vertical planes 40 inches apart, extending across the full width of the vehicle. The Federal single axle weight limit on the Interstate System is 20,000 pounds.
Special mobile equipment. Every self-propelled vehicle not designed or used primarily for the transportation of persons or property and incidentally operated or moved over the highways, including military equipment, farm equipment, implements of husbandry, road construction or maintenance machinery, and emergency apparatus which includes fire and police emergency equipment. This list is partial and not exclusive of such other vehicles as may fall within the general terms of this definition.
Stinger-steered combination. A truck tractor semitrailer wherein the fifth wheel is located on a drop frame located behind and below the rear-most axle of the power unit.
Tandem axle weight. The total weight transmitted to the road by two or more consecutive axles whose centers may be included between parallel transverse vertical planes spaced more than 40 inches and not more than 96 inches apart, extending across the full width of the vehicle. The Federal tandem axle weight limit on the Interstate System is 34,000 pounds.
Terminal. The term terminal as used in this regulation means, at a minimum, any location where:
Freight either originates, terminates, or is handled in the transportation process; or
Commercial motor carriers maintain operating facilities.
Tractor or Truck tractor. The noncargo carrying power unit that operates in combination with a semitrailer or trailer, except that a truck tractor and semitrailer engaged in the transportation of automobiles may transport motor vehicles on part of the power unit, and a truck tractor equipped with a dromedary unit operating in combination with a semitrailer transporting Class 1 explosives and/or any munitions related security material as specified by the U.S. Department of Defense in compliance with 49 CFR 177.835 may use the dromedary unit to carry a portion of the cargo.
Truck-tractor semitrailer-semitrailer. In a truck-tractor semitrailer-semitrailer combination vehicle, the two trailing units are connected with a “B-train” assembly. The B-train assembly is a rigid frame extension attached to the rear frame of a first semitrailer which allows for a fifth wheel connection point for the second semitrailer. This combination has one less articulation point than the conventional “A dolly” connected truck-tractor semitrailer-trailer combination.
Truck-trailer boat transporter. A boat transporter combination consisting of a straight truck towing a trailer using typically a ball and socket connection. The trailer axle(s) is located substantially at the trailer center of gravity (rather than the rear of the trailer) but so as to maintain a downward force on the trailer tongue.
Width exclusive devices. Devices excluded from the measurement of vehicle width. Such devices shall not be designed or used to carry cargo.
[49 FR 23315, June 5, 1984, as amended at 53 FR 2597, Jan. 29, 1988; 53 FR 12148, Apr. 13, 1988; 53 FR 25485, July 7, 1988; 53 FR 48636, Dec. 2, 1988; 55 FR 22762, June 1, 1990; 55 FR 32399, Aug. 9, 1990; 59 FR 30419, June 13, 1994; 63 FR 70652, Dec. 22, 1998; 64 FR 48959, Sept. 9, 1999; 67 FR 15109, Mar. 29, 2002; 68 FR 37968, June 26, 2003; 69 FR 11996, Mar. 12, 2004]
§ 658.7 Applicability.
top
Except as limited in §658.17(a) the provisions of this part are applicable to the National Network and reasonable access thereto. However, nothing in this regulation shall be construed to prevent any State from applying any weight and size limits to other highways, except when such limits would deny reasonable access to the National Network.
§ 658.9 National Network criteria.
top
(a) The National Network listed in the appendix to this part is available for use by commerical motor vehicles of the dimensions and configurations described in §§658.13 and 658.15.
(b) For those States with detailed lists of individual routes in the appendix, the routes have been designated on the basis of their general adherence to the following criteria.
(1) The route is a geometrically typical component of the Federal-Aid Primary System, serving to link principal cities and densely developed portions of the States.
(2) The route is a high volume route utilized extensively by large vehicles for interstate commerce.
(3) The route does not have any restrictions precluding use by conventional combination vehicles.
(4) The route has adequate geometrics to support safe operations, considering sight distance, severity and length of grades, pavement width, horizontal curvature, shoulder width, bridge clearances and load limits, traffic volumes and vehicle mix, and intersection geometry.
(5) The route consists of lanes designed to be a width of 12 feet or more or is otherwise consistent with highway safety.
(6) The route does not have any unusual characteristics causing current or anticipated safety problems.
(c) For those States where State law provides that STAA authorized vehicles may use all or most of the Federal-Aid Primary system, the National Network is no more restrictive than such law. The appendix contains a narrative summary of the National Network in those States.
[49 FR 23315, June 5, 1984, as amended at 53 FR 12148, Apr. 13, 1988]
§ 658.11 Additions, deletions, exceptions, and restrictions.
top
To ensure that the National Network remains substantially intact, FHWA retains the authority to rule upon all requested additions to and deletions from the National Network as well as requests for the imposition of certain restrictions. FHWA approval or disapproval will constitute the final decision of the U.S. Department of Transportation.
(a) Additions. (1) Requests for additions to the National Network, including justification, shall have the endorsement of the Governor or the Governor's authorized representative, and be submitted in writing to the appropriate FHWA Division Office. Proposals for addition of routes to the National Network shall be accompanied by an analysis of suitability based on the criteria in §658.9.
(2) Proposals for additions that meet the criteria of §658.9 and have the endorsement of the Governor or the Governor's authorized representative will be published in the Federal Register for public comment as a notice of proposed rulemaking (NPRM), and if found acceptable, as a final rule.
(b) Deletions—Federal-aid primary—other than interstate. Changed conditions or additional information may require the deletion of a designated route or a portion thereof. The deletion of any route or route segment shall require FHWA approval. Requests for deletion of routes from the National Network, including the reason(s) for the deletion, shall be submitted in writing to the appropriate FHWA Division Office. These requests shall be assessed on the basis of the criteria of §658.9. FHWA proposed deletions will be published in the Federal Register as a Notice of Proposed Rulemaking (NPRM).
(c) Requests for deletion—Federal-aid primary—other than interstate. Requests for deletion should include the following information, where appropriate:
(1) Did the route segment prior to designation carry combination vehicles or 102-inch buses?
(2) Were truck restrictions in effect on the segment on January 6, 1983? If so, what types of restrictions?
(3) What is the safety record of the segment, including current or anticipated safety problems? Specifically, is the route experiencing above normal accident rates and/or accident severities? Does analysis of the accident problem indicate that the addition of larger trucks have aggravated existing accident problems?
(4) What are the geometric, structural or traffic operations features that might preclude safe, efficient operation? Specifically describe lane widths, sight distance, severity and length of grades, horizontal curvature, shoulder width, narrow bridges, bridge clearances and load limits, traffic volumes and vehicle mix, intersection geometrics and vulnerability of roadside hardware.
(5) Is there a reasonable alternate route available?
(6) Are there operational restrictions that might be implemented in lieu of deletion?
(d) Deletions and use restrictions—Federal-aid interstate. (1) The deletion of, or imposition of use restrictions on, any specific segment of the Interstate Highway System on the National Network, except as otherwise provided in this part, must be approved by the FHWA. Such action will be initiated on the FHWA's own initiative or on the request of the Governor or the Governor's authorized representative of the State in which the Interstate segment is located. Requests from the Governor or the Governor's authorized representative shall be submitted along with justification for the deletion or restriction, in writing, to the appropriate FHWA Division Office for transmittal to Washington Headquarters.
(2) The justification accompanying a request shall be based on the following:
(i) Analysis of evidence of safety problems supporting the deletion or restriction as identified in §658.11(c).
(ii) Analysis of the impact on interstate commerce.
(iii) Analysis and recommendation of any alternative routes that can safely accommodate commercial motor vehicles of the dimensions and configurations described in §§658.13 and 658.15 and serve the area in which such segment is located.
(iv) Evidence of consultation with the local governments in which the segment is located as well as the Governor or the Governor's authorized representative of any adjacent State that might be directly affected by such a deletion or restriction.
(3) Actions to ban all commercial vehicles on portions of the Interstate System not excepted under §658.11(f) are considered deletions subject to the requirements of subsection (d) of this section.
(4) Reasonable restrictions on the use of Interstate routes on the National Network by STAA-authorized vehicles related to specific travel lanes of multi-lane facilities, construction zones, adverse weather conditions or structural or clearance deficiencies are not subject to the requirements of paragraph (d) of this section.
(5) Proposed deletions or restrictions will be published in the Federal Register as an NPRM, except in the case of an emergency deletion as prescribed in §658.11(e). The FHWA will consider the factors set out in paragraph (d)(2) of this section and the comments of interested parties. Any approval of deletion or restriction will be published as a final rule. A deletion of or restriction on a segment for reasons ascribable to dimensions of commercial motor vehicles described in either §658.13 or §658.15 shall result in a deletion or restriction for the purposes of both §§658.13 and 658.15.
(e) Emergency deletions. FHWA has the authority to delete any route from the National Network, on an emergency basis, for safety considerations. Emergency deletions are not considered final, and will be published in the Federal Register for notice and comment.
(f) Exceptions. Those portions of the Interstate System which were open to traffic and on which all commercial motor vehicles were banned on January 6, 1983, are not included in the National Network.
(g) Restrictions—Federal-aid primary—other than interstate. (1) Reasonable restrictions on the use of non-Interstate Federal-aid Primary routes on the National Network by STAA-authorized vehicles may be imposed during certain peak hours of travel or on specific travel lanes of multi-lane facilities. Restrictions related to construction zones, seasonal operation, adverse weather conditions or structural or clearance deficiencies may be imposed.
(2) All restrictions on the use of the National Network based on hours of use by vehicles authorized by the STAA require prior FHWA approval. Requests for such restrictions on the National Network shall be submitted in writing to the appropriate FHWA Division Office. Approval of requests for restrictions will be contingent on the ability to justify significant negative impact on safety, the environment and/or operational efficiency.
[49 FR 23315, June 5, 1984, as amended at 53 FR 12148, Apr. 13, 1988]
§ 658.13 Length.
top
(a) The length provisions of the STAA apply only to the following types of vehicle combinations:
(1) Truck tractor-semitrailer
(2) Truck tractor-semitrailer-trailer.
The length provisions apply only when these combinations are in use on the National Network or in transit between these highways and terminals or service locations pursuant to §658.19.
(b) The length provisions referred to in paragraph (a) of this section include the following:
(1) No State shall impose a length limitation of less than 48 feet on a semitrailer operating in a truck tractor-semitrailer combination.

(3) No State shall impose an overall length limitation on commercial vehicles operating in truck tractor-semitrailer or truck tractor-semitrailer-trailer combinations.
(4) No State shall prohibit commercial motor vehicles operating in truck tractor-semitrailer-trailer combinations.
(5) No State shall prohibit the operation of semitrailers or trailers which are 281/2 feet long when operating in a truck tractor-semitrailer-trailer combination if such a trailer or semitrailer was in actual and lawful operation on December 1, 1982, and such combination had an overall length not exceeding 65 feet.
(c) State maximum length limits for semitrailers operating in a truck tractor-semitrailer combination and semitrailers and trailers operating in a truck tractor-semitrailer-trailer combination are subject to the following:
(1) No State shall prohibit the use of trailers or semitrailers of such dimensions as those that were in actual and lawful use in such State on December 1, 1982, as set out in appendix B of this part.
(2) If on December 1, 1982, State length limitations on a semitrailer were described in terms of the distance from the kingpin to rearmost axle, or end of semitrailer, the operation of any semitrailer that complies with that limitation must be allowed.
(d) No State shall impose a limit of less than 45 feet on the length of any bus on the NN.
(e) Specialized equipment—(1) Automobile transporters. (i) Automobile transporters are considered to be specialized equipment. As provided in §658.5, automobile transporters may carry vehicles on the power unit behind the cab and on an over-cab rack. No State shall impose an overall length limitation of less than 65 feet on traditional automobile transporters (5th wheel located on tractor frame over rear axle(s)), including “low boys,” or less than 75 feet on stinger-steered automobile transporters. Paragraph (c) requires the States to allow operation of vehicles with the dimensions that were legal in the State on December 1, 1982.
(ii) All length provisions regarding automobile transporters are exclusive of front and rear cargo overhang. No State shall impose a front overhang limitation of less than 3 feet or a rear overhang limitation of less than 4 feet. Extendable ramps or “flippers” on automobile transporters that are used to achieve the allowable 3-foot front and 4-foot rear cargo overhangs are excluded from the measurement of vehicle length, but must be retracted when not supporting vehicles.
(iii) Drive-away saddlemount vehicle transporter combinations and driveaway saddlemount with fullmount vehicle transporter combinations are considered to be specialized equipment. No State shall impose an overall length limit of less than 75 feet on such combinations. This provision applies to saddlemount combinations with up to three saddlemounted vehicles. Such combinations may include one fullmount. Saddlemount combinations must also comply with the applicable safety regulations at 49 CFR 393.71.
(2) Boat transporters. (i) Boat transporters are considered to be specialized equipment. As provided for automobile transporters in §658.5, boat transporters may carry boats on the power unit so long as the length and width restrictions of the vehicles and load are not exceeded. No State shall impose an overall length limitation of less than 65 feet on traditional boat transporters (fifth wheel located on tractor frame over rear axle(s), including “low boys,” or less than 75 feet on stinger-steered boat transporters. In addition, no State shall impose an overall length limitation of less than 65 feet on truck-trailer boat transporters. Paragraph (c) of this section requires the States to allow operation of vehicles with the dimensions that were legal in the State on December 1, 1982.
(ii) All length provisions regarding boat transporters are exclusive of front and rear overhang. Further, no State shall impose a front overhang limitation of less than three (3) feet nor a rearmost overhang limitation of less than four (4) feet.
(3) Truck-tractor semitrailer-semitrailer. (i) Truck-tractor semitrailer-semitrailer combination vehicles are considered to be specialized equipment. No State shall impose a length limitation of less than 28 feet on any semitrailer or 281/2 feet if the semitrailer was in legal operation on December 1, 1982, operating in a truck-tractor semitrailer-semitrailer combination. No State shall impose an overall length limitation on a truck-tractor semitrailer-semitrailer combination when each semitrailer length is 28 feet, or 281/2 feet if grandfathered.
(ii) The B-train assembly is excluded from the measurement of trailer length when used between the first and second trailer of a truck-tractor semitrailer-semitrailer combination vehicle. However, when there is no semitrailer mounted to the B-train assembly, it will be included in the length measurement of the semitrailer, the length limitation in this case being 48 feet, or longer if grandfathered.
(4) Maxi-cube vehicle. No State shall impose a length limit on a maxi-cube vehicle, as defined in §658.5 of this part, of less than 34 feet on either cargo box, excluding drawbar or hitching device; 60 feet on the distance from the front of the first to the rear of the second cargo box, including the space between the cargo boxes; or 65 feet on the overall length of the combination, including the space between the cargo boxes. The measurement for compliance with the 60- and 65-foot distance shall include the actual distance between cargo boxes, measured along the centerline of the drawbar or hitching device. For maxi-cubes with an adjustable length drawbar or hitching device, the 60- and 65-foot distances shall be measured with a drawbar spacing of not more than 27 inches. The drawbar may be temporarily extended beyond that distance to maneuver or load the vehicle.
(5) Beverage semitrailer. (i) A beverage semitrailer is specialized equipment if it has an upper coupler plate that extends beyond the front of the semitrailer, but not beyond its swing radius, as measured from the center line of the kingpin to a front corner of the semitrailer, which cannot be used for carrying cargo other than the structure of the semitrailer, and with the center line of the kingpin not more than 28 feet from the rear of the semitrailer (exclusive of rear-mounted devices not measured in determining semitrailer length). No State shall impose an overall length limit on such vehicles when operating in a truck tractor-beverage semitrailer or truck tractor-beverage semitrailer-beverage trailer combination on the NN.
(ii) The beverage trailer referred to in paragraph (e)(5)(i) of this section means a beverage semitrailer and converter dolly. Converter dolly has the same meaning as in 49 CFR 393.5.
(iii) Truck tractor-beverage semitrailer combinations shall have the same access to points of loading and unloading as 28-foot semitrailers (28.5-foot where allowed by §658.13) in 23 CFR 658.19.
(6) Munitions carriers using dromedary equipment. A truck tractor equipped with a dromedary unit operating in combination with a semitrailer is considered to be specialized equipment, providing the combination is transporting Class 1 explosives and/or any munitions related security material as specified by the U.S. Department of Defense in compliance with 49 CFR 177.835. No State shall impose an overall length limitation of less than 75 feet on the combination while in operation.
(f) A truck tractor containing a dromedary box, deck, or plate in legal operation on December 1, 1982, shall be permitted to continue to operate, notwithstanding its cargo carrying capacity, throughout its useful life. Proof of such legal operation on December 1, 1982, shall rest upon the operator of the equipment.
(g) No State shall impose a limitation of less than 46 feet on the distance from the kingpin to the center of the rear axle on trailers or semitrailers used exclusively or primarily to transport vehicles in connection with motorsports competition events.

(c) The maximum gross weight upon any one axle, including any one axle of a group of axles, or a vehicle is 20,000 pounds.
(d) The maximum gross weight on tandem axles is 34,000 pounds.
(e) No vehicle or combination of vehicles shall be moved or operated on any Interstate highway when the gross weight on two or more consecutive axles exceeds the limitations prescribed by the following formula, referred to as the Bridge Gross Weight Formula:
except that two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each if the overall distance between the first and last axle is 36 feet or more. In no case shall the total gross weight of a vehicle exceed 80,000 pounds.
(f) Except as provided herein, States may not enforce on the Interstate System vehicle weight limits of less than 20,000 pounds on a single axle, 34,000 pounds on a tandem axle, or the weights derived from the Bridge Formula, up to a maximum of 80,000 pounds, including all enforcement tolerances. States may not limit tire loads to less than 500 pounds per inch of tire or tread width, except that such limits may not be applied to tires on the steering axle. States may not limit steering axle weights to less than 20,000 pounds or the axle rating established by the manufacturer, whichever is lower.
(g) The weights in paragraphs (b), (c), (d), and (e) of this section shall be inclusive of all tolerances, enforcement or otherwise, with the exception of a scale allowance factor when using portable scales (wheel-load weighers). The current accuracy of such scales is generally within 2 or 3 percent of actual weight, but in no case shall an allowance in excess of 5 percent be applied. Penalty or fine schedules which impose no fine up to a specified threshold, i.e., 1,000 pounds, will be considered as tolerance provisions not authorized by 23 U.S.C. 127.
(h) States may issue special permits without regard to the axle, gross, or Federal Bridge Formula requirements for nondivisible vehicles or loads.
(i) The provisions of paragraphs (b), (c), and (d) of this section shall not apply to single-, or tandem-axle weights, or gross weights legally authorized under State law on July 1, 1956. The group of axles requirement established in this section shall not apply to vehicles legally grandfathered under State groups of axles tables or formulas on January 4, 1975. Grandfathered weight limits are vested on the date specified by Congress and remain available to a State even if it chooses to adopt a lower weight limit for a time.
(j) The provisions of paragraphs (c) through (e) of this section shall not apply to the operation on Interstate Route 68 in Allegany and Garrett Counties, Maryland, of any specialized vehicle equipped with a steering axle and a tridem axle and used for hauling coal, logs, and pulpwood if such vehicle is of a type of vehicle as was operating in such counties on U.S. Routes 40 or 48 for such purposes on August 1, 1991.
(k) Any vehicle which is regularly and exclusively used as an intrastate public agency transit passenger bus is excluded from the axle weight limits in paragraphs (c) through (e) of this section until October 1, 2003.
(l) The provisions of paragraphs (b) through (e) of this section shall not apply to the operation, on the 104 mile portion of I–39 between I–90/94 near Portage, Wisconsin, and Wisconsin State Route 29 south of Wausau, Wisconsin, of any vehicle that could legally operate on this highway section before November 28, 1995.
(m) The provisions of paragraphs (b) through (e) of this section shall not apply to the operation, on I–99 between Bedford and Bald Eagle, Pennsylvania, of any vehicle that could legally operate on this highway section before December 29, 1995.

§ 658.19 Reasonable access.
top
(a) No State may enact or enforce any law denying reasonable access to vehicles with dimensions authorized by the STAA between the NN and terminals and facilities for food, fuel, repairs, and rest. In addition, no State may enact or enforce any law denying reasonable access between the NN and points of loading and unloading to household goods carriers, motor carriers of passengers, and any truck tractor-semitrailer combination in which the semitrailer has a length not to exceed 28 feet (28.5 feet where allowed pursuant to §658.13(b)(5) of this part) and which generally operates as part of a vehicle combination described in §§658.13(b)(5) and 658.15(a) of this part.
(b) All States shall make available to commercial motor vehicle operators information regarding their reasonable access provisions to and from the National Network.
(c) Nothing in this section shall be construed as preventing any State or local government from imposing any reasonable restriction, based on safety considerations, on access to points of loading and unloading by any truck tractor-semitrailer combination in which the semitrailer has a length not to exceed 281/2 feet and which generally operates as part of a vehicle combination described in §§658.13(b)(5) and 658.15(a).
(d) No State may enact or enforce any law denying access within 1 road-mile from the National Network using the most reasonable and practicable route available except for specific safety reasons on individual routes.
(e) Approval of access for specific vehicles on any individual route applies to all vehicles of the same type regardless of ownership. Distinctions between vehicle types shall be based only on significant, substantial differences in their operating characteristics.
(f) Blanket restrictions on 102-inch wide vehicles may not be imposed.
(g) Vehicle dimension limits shall not be more restrictive than Federal requirements.
(h) States shall ensure compliance with the requirements of this section for roads under the jurisdiction of local units of government.
(i)(1) Except in those States in which State law authorizes the operation of STAA-dimensioned vehicles on all public roads and highways, all States shall have an access review process that provides for the review of requests for access from the National Network.
(2) State access review processes shall provide for:
(i) One or more of the following:
(A) An analysis of the proposed access routes using observations or other data obtained from the operation of test vehicles over the routes;
(B) An analysis of the proposed access routes by application of vehicle templates to plans of the routes;
(C) A general provision for allowing access, without requiring a request, for commercial motor vehicles with semitrailers with a kingpin distance of 41 feet or less (measured from the kingpin to the center of the rear axle, if single, or the center of a group of rear axles). State safety analyses may be conducted on individual routes if warranted; and
(ii) All of the following:
(A) The denial of access to terminals and services only on the basis of safety and engineering analysis of the access route.
(B) The automatic approval of an access request if not acted upon within 90 days of receipt by the State. This provision shall become effective no later than 12 months following the effective date of this rule unless an extension is requested by the State and approved by FHWA.
(C) The denial of access for any 102-inch wide vehicles only on the basis of the characteristics of specific routes, in particular significant deficiencies in lane width.
(j)(1) Each State shall submit its access provisions to FHWA for approval within 6 months after June 1, 1990. In those States in which State law authorizes the operation of STAA-dimensioned vehicles on all public roads and highways, no submission or approval under this paragraph is required. If, in the future, such a State changes its authorizing legislation and restricts the operation of STAA-dimensioned vehicles, then compliance with these provisions will be necessary.
(2) The FHWA will review the access provisions as submitted by each State subject to the provisions in paragraph (j)(1) and approve those that are in compliance with the requirements of this section. The FHWA may, at a State's request, approve State provisions that differ from the requirements of this section if FHWA determines that they provide reasonable access for STAA-dimensioned vehicles and do not impose an unreasonable burden on motor freight carriers, shippers and receivers and service facility operators.
(3) Any State that does not have FHWA approved access provisions in effect within 1 year after June 1, 1990 shall follow the requirements and the criteria set forth in this section and section 658.5 and 658.19 for determining access for STAA-dimensioned vehicles to terminals and services. The FHWA may approve a State's request for a time extension if it is received by FHWA at least 1 month before the end of the 1 year period.
[53 FR 12149, Apr. 13, 1988, as amended at 55 FR 22763, June 1, 1990; 59 FR 30420, June 13, 1994]
§ 658.21 Identification of National Network.
top
(a) To identify the National Network, a State may sign the routes or provide maps of lists of highways describing the National Network.
(b) Exceptional local conditions on the National Network shall be signed. All signs shall conform to the Manual on Uniform Traffic Control Devices. Exceptional conditions shall include but not be limited to:
(1) Operational restrictions designed to maximize the efficiency of the total traffic flow, such as time of day prohibitions, or lane use controls.
(2) Geometric and structural restrictions, such as vertical clearances, posted weight limits on bridges, or restrictions caused by construction operations.
(3) Detours from urban Interstate routes to bypass of circumferential routes for commercial motor vehicles not destined for the urban area to be bypassed.
§ 658.23 LCV freeze; cargo-carrying unit freeze.
top
(a)(1) Except as otherwise provided in this section and except for tow trucks with vehicles in tow, a State may allow the operation of LCV's on the Interstate System only as listed in appendix C to this part.
(2) Except as otherwise provided in this section, a State may not allow the operation on the NN of any CMV combination with two or more cargo-carrying units (not including the truck tractor) whose cargo-carrying units exceed:
(i) The maximum combination trailer, semitrailer, or other type of length limitation authorized by State law or regulation of that State on or before June 1, 1991; or
(ii) The length of the cargo-carrying units of those CMV combinations, by specific configuration, in actual, lawful operation on a regular or periodic basis (including continuing seasonal operation) in that State on or before June 1, 1991, as listed in appendix C to this part.
(b) Notwithstanding paragraph (a)(2) of this section, the following CMV combinations with two or more cargo-carrying units may operate on the NN.
(1) Truck tractor-semitrailer-trailer and truck tractor-semitrailer-semitrailer combinations with a maximum length of the individual cargo units of 28.5 feet or less.
(2) Vehicles described in §658.13(e) and (g).
(3) Truck-trailer and truck-semitrailer combinations with an overall length of 65 feet or less.
(4) Maxi-cubes.
(5) Tow trucks with vehicles in tow.
(c) For specific safety purposes and road construction, a State may make minor adjustments of a temporary and emergency nature to route designations and vehicle operating restrictions applicable to combinations subject to 23 U.S.C. 127(d) and 49 U.S.C. 31112 and in effect on June 1, 1991 (July 6, 1991, for Alaska). Adjustments which last 30 days or less may be made without notifying the FHWA. Minor adjustments which exceed 30 days require approval of the FHWA. When such adjustments are needed, a State must submit to the Division Office of Motor Carriers, by the end of the 30th day, a written description of the emergency, the date on which it began, and the date on which it is expected to conclude. If the adjustment involves route designations, the State shall describe the new route on which vehicles otherwise subject to the freeze imposed by 23 U.S.C. 127(d) and 49 U.S.C. 31112 are allowed to operate. To the extent possible, the geometric and pavement design characteristics of the alternate route should be equivalent to those of the highway section which is temporarily unavailable. Approval or disapproval by Office of Motor Carriers officials of adjustments involving route designations shall be coordinated with the Division Administrator. If the adjustment involves vehicle operating restrictions, the State shall list the restrictions that have been removed or modified. Approval or disapproval of the adjustment by the Division Office of Motor Carriers shall take place only after consultation with the Regional Office of Motor Carriers. If the adjustment is approved, a copy of the approved submission shall be forwarded through the Regional Office of Motor Carriers, to the Associate Administrator for Motor Carriers at Headquarters, who will publish the notice of adjustment, with an expiration date, in the Federal Register. Requests for extensions of time beyond the originally established conclusion date shall be subject to the same approval and publication process as the original request. If upon consultation with the Regional Office of Motor Carriers, a decision is reached that minor adjustments made by a State are not legitimately attributable to road or bridge construction or safety, the Division Office of Motor Carriers will so inform the State, and the original conditions of the freeze must be reimposed immediately. Failure to do so may subject the State to a penalty pursuant to 23 U.S.C. 141.
(d) A State may issue a permit authorizing a CMV to transport an overlength nondivisible load on two or more cargo-carrying units on the NN without regard to the restrictions in §658.23(a)(2).
(e) States further restricting or prohibiting the operation of vehicles subject to 23 U.S.C. 127(d) and 49 U.S.C. 31112 after June 1, 1991, shall notify the FHWA Division Office of Motor Carriers within 30 days after the restriction is effective. The Division Office of Motor Carriers shall forward the information through the Regional Office of Motor Carriers to the Associate Administrator for Motor Carriers at Headquarters. The FHWA will publish the restriction in the Federal Register as an amendment to appendix C to this part. Failure to provide such notification may subject the State to a penalty pursuant to 23 U.S.C. 141.
(f) The Federal Highway Administrator, on his or her own motion or upon a request by any person (including a State), shall review the information set forth in appendix C to this part. If the Administrator determines there is cause to believe that a mistake was made in the accuracy of the information contained in appendix C to this part, the Administrator shall commence a proceeding to determine whether the information published should be corrected. If the Administrator determines that there is a mistake in the accuracy of the information contained in appendix C to this part, the Administrator shall publish in the Federal Register the appropriate corrections to reflect that determination.

Appendix C to Part 658—Trucks Over 80,000 Pounds on the Interstate System and Trucks Over STAA Lengths on the National Network
top
This appendix contains the weight and size provisions that were in effect on or before June 1, 1991 (July 6, 1991 for Alaska), for vehicles covered by 23 U.S.C. 127(d) (LCV's) and 49 U.S.C. app. 2311(j) (commercial motor vehicles (CMV's) with 2 or more cargo-carrying units). Weights and dimensions are “frozen” at the values shown here, which were in effect on June 1, 1991 (Alaska, July 6, 1991). All vehicles are listed by configuration type.
Trucks Over 80,000 Pounds on the Interstate System
In the State-by-State descriptions, CMV combinations which can also be LCV's are identified with the letters “LCV” following the type of combination vehicle. The maximum allowable gross vehicle weight is given in this appendix (in thousands of pounds indicated by a “K”), as well as information summarizing the operational conditions, routes, and legal citations. The term “Interstate System” as used herein refers to the Dwight D. Eisenhower System of Interstate and Defense Highways.
Trucks Over STAA Lengths on the National Network
Listed for each State by combination type is either:
1. The maximum cargo-carrying length (shown in feet); or
2. A notation that such vehicle is not allowed (indicated by a “NO”).
CMV's are categorized as follows:
1. A CMV combination consisting of a truck tractor and two trailing units.
2. A CMV combination consisting of a truck tractor and three trailing units.
3. CMV combinations with two or more cargo-carrying units not included in descriptions 1 or 2.
In the following table the left number is the maximum cargo-carrying length measured in feet from the front of the first cargo unit to the rear of the last cargo unit. This distance is not to include length exclusive devices which have been approved by the Secretary or by any State. Devices excluded from length determination shall only include items whose function is related to the safe and efficient operation of the semitrailer or trailer. No device excluded from length determination shall be designed or used for carrying cargo. The right number is the maximum gross weight in thousands of pounds that the type of vehicle can carry when operating as an LCV on the Interstate System. For every State where there is a length or weight number in the table that follows, additional information is provided.

Florida's combination is not allowed to operate on the Interstate System, and the combinations for Hawaii, Mississippi, and Nebraska are not allowed to exceed 80,000 pounds.(3)_No maximum cargo-carrying length is established for this combination. Because State law limits each trailing unit to not more than 28.5 feet in length, this combination is allowed to operate on all NN routes under the authority of the STAA of 1982, regardless of actual cargo-carrying length. The maximum weight listed is New Mexico's maximum allowable gross weight on the Interstate System under the grandfather authority of 23 U.S.C. 127.(4)_These dimensions do not apply to the same combinations. The 110-foot length is limited to vehicles entering from Oklahoma, also limited to 90K gross weight. The 120K gross weight is limited to vehicles entering from Kansas, also limited to a cargo carrying length of 109 feet.

LENGTH OF THE CARGO-CARRYING UNITS: 109 feet
MAXIMUM ALLOWABLE GROSS WEIGHT: 120,000 pounds
OPERATIONAL CONDITIONS: The operations of triple trailing unit combinations are governed by two sets of criteria: (1) The Turnpike and Turnpike access rules, and (2) the SVC rules which apply off of the Turnpike except in the case of vehicles operating under Turnpike access authority. The Turnpike and Turnpike access rules allow a maximum combination vehicle length of 119 feet overall. The SVC rules require “Triples” to have trailers of no more than 28.5 feet maximum length or a cargo-carrying length of approximately 95 feet.
The Turnpike and Turnpike access rules have no time-of-day travel restrictions or other special requirements.
The SVC rules have several operational conditions. SVC's cannot operate on holidays or during holiday weekends. SVC's cannot be dispatched or operated during adverse weather conditions. SVC's must travel in the right lane, except for passing, and the following distance is 100 feet for every 10 miles per hour. SVC permits can include any restrictions deemed necessary, including specific routes and hours, days, and/or seasons of operation. Rules and regulations can be promulgated regarding driver qualifications, vehicle equipment, and operational standards.
WEIGHT: All triple trailing unit combinations must comply with the Federal Bridge Formula with maximum axle weights of 20,000 pounds on a single axle and 34,000 pounds on a tandem axle. The maximum gross weight is 120,000 pounds on the Turnpike and Turnpike access routes, but the SVC's have a maximum weight of 110,000 pounds.
DRIVER: A commercial driver's license with the appropriate endorsement is required under both Turnpike and SVC rules. In addition, for SVC operation drivers must have completed SVC driver training and a company road test. Drivers must also have 2 years of experience driving tractor-semitrailers and 1 year driving doubles.
VEHICLE: Vehicle requirements apply to the SVC program only. All axles, except steering axles, must have dual wheels, and all vehicles must be able to achieve and maintain a speed of 40 miles per hour on all grades. Antispray mud flaps shall be attached to the rear of each axle except the steering axle. Mud flaps shall have a surface designed to absorb and deflect excess moisture to the road surface. Drop and lift axles are prohibited. Vehicles may have a minimum of six and a maximum of nine axles. The heaviest trailers are to be placed forward. Hazardous cargo is prohibited. Convex mirrors are required on both sides of the cab. Equipment must comply with the requirements of 49 CFR 390–399.
Any SVC shall be stable at all times during normal braking and normal operation. When traveling on a level, smooth paved surface, an SVC shall follow the towing vehicle without shifting or swerving beyond the restraints of the lane of travel.
PERMIT: Same as the KS-TT2 combination on the Turnpike and Turnpike access routes. A fee per company plus a permit fee for each power unit is required for the SVC program, and the SVC permits are valid for 1 year. SVC's operated pursuant to regulation 36–1–33 under an annual permit shall be covered by insurance.
ACCESS: Turnpike access routes include all routes between the Turnpike and a motor freight terminal located within a 10-mile radius of each toll booth, except at the northeastern end of the Turnpike where a 20-mile radius is allowed.

For an eight-axle combination: Drive axles—36,000 pounds, axles four/five—36,000 pounds, sixth axle—22,400 pounds, and axles seven/eight—36,000 pounds. The eight-axle LCV has no minimum axle-spacing requirements. For gross weights in excess of 138,400 pounds the combination must include a tandem-axle dolly to meet the nine-axle requirements. Maximum permissible gross weight for B-train combination is 127,000 pounds.
When the gross weight of the two trailers in a tandem combination vary more than 20 percent, the heaviest of the two must be placed in the lead position.
For tandem trailer combinations in which neither trailing unit exceeds 28.5 feet in length the following maximum allowable weights apply: for a single axle—28,000 pounds (except that steering axles may not exceed 22,400 pounds), for a tandem axle—42,500 pounds, for a tri-axle—52,500 pounds. The gross weight may not exceed 100,000 pounds or the manufacturers gross weight rating, whichever is lower.
DRIVER: For operation on highways under the jurisdiction of the New York State Thruway Authority (NYSTA), except for the full length of I–84 and that portion of I–287 from Thruway exit 8 to I–95, the driver must have a commercial driver's license with the appropriate endorsement, and hold a Tandem Trailer Driver's Permit issued by the NYSTA. In order to obtain an NYSTA driver's permit, an applicant must (1) hold a valid commercial driver's license with multiple-trailer endorsement; (2) be over 26 years old, in good health, and have at least 5 years of provable experience driving tractor-trailer combinations; and (3) meet all other application requirements with regard to driving history established by the NYSTA. Qualified drivers receive a Tandem Trailer Driver's Permit for Tandem Vehicle Operation which is valid only for the operation of the certified equipment owned by the company to which the permit is issued.
For operation on highways under the jurisdiction of the New York State DOT, cities not wholly included in one county, the full length of I–84 and that portion of I–287 from Thruway exit 8 to I–95, the driver must have a commercial driver's license with the appropriate endorsement.
VEHICLE: All vehicles must meet the requirements of applicable Federal and State statutes, rules, and regulations. Vehicles operating on highways under the jurisdiction of the NYSTA, except for the full length of I–84 and that portion of I–287 from Thruway exit 8 to I–95, must also meet the following additional requirements. The tractor manufacturer and the permittee shall certify to the NYSTA prior to the approval of the tractor that it is capable of hauling the maximum permissible gross load at a speed of not less than 20 miles per hour on all portions of the thruway system.
The brakes on any vehicle, dolly converter, or combination of vehicles shall comply with 49 CFR part 393 and, in addition, any vehicle or dolly converter shall meet the provisions of the New York State Traffic Law.
Tandem trailer operations shall be equipped, at a minimum, with emergency equipment as required by 49 CFR part 393, subpart H, as amended, tire chains from October 15 to May 1 of each year, a fire extinguisher with an aggregate rating of 20BC, and each trailer with specific lamps and reflectors.
All tractors certified by the NYSTA for use with tandem trailers will be assigned an identification number by the NYSTA which must be placed on the vehicle. The number must be at least 3 inches in height and visible to a person standing at ground level opposite the driver's position in the cab.
Axle Type. Tractors to be used for hauling 110,000 pounds or more shall be equipped with tandem rear axles, both with driving power. Tractors to be used for hauling 110,000 pounds or less may have a single drive axle. Tandem combinations using single wheel tires commonly referred to as “Super Singles” are required to use triple-axle tractors, dual-axle trailers, and dual-axle dollies.
Dollies. Every converter dolly certified on and after June 1, 1968, used to convert a semitrailer to a full trailer may have either single or tandem axles at the option of the permittee. Single-axle dollies may not utilize low profile tires. Combination vehicles with a gross weight in excess of 138,400 pounds must have a tandem-axle dolly to meet the nine-axle requirement. If the distance between two semitrailers is 10 feet or more, the dolly shall be equipped with a device or the trailers connected along the sides with suitable material to indicate they are in effect one unit. The devices or connection shall be approved by the NYSTA prior to use on a tandem trailer combination. The NYSTA tandem-trailer provisions require that converter dollies shall be coupled with one or more safety chains or cables to the frame or an extension of the frame of the motor vehicle by which it is towed. Each dolly converter must also be equipped with mud flaps. Tandem combinations using a sliding fifth wheel attached to the lead trailer, known as a “B-Train” combination, will require a separate Thruway Engineer Service approval prior to the initial tandem run. Special provisions regarding B-Trains will be reviewed at the time of the application or request for use on the Thruway.
PERMIT: For operation on highways under the jurisdiction of the New York State DOT, cities not wholly included in one county, or the following highway sections under NYSTA jurisdiction; the full length of I–84 and that portion of I–287 from Thruway exit 8 to I–95, a permit to exceed the weight limits set forth in section 385(15) of the New York State Vehicle and Traffic Law must be obtained from the State DOT, city involved, or the NYSTA. A fee is charged for the permit.
For operation on highways under the jurisdiction of the NYSTA, except for the full length of I–84 and that portion of I–287 from Thruway exit 8 to I–95, companies must file an application for a Tandem Trailer Permit with the NYSTA. Permits are issued to such companies upon meeting qualifications, including insurance, for tandem combinations over 65 feet in length. No permit fee is charged; however, Thruway tolls are charged for each use of the Thruway, and the equipment must be certified by the NYSTA annually. The annual re-certification of equipment is handled by: New York State Thruway Authority, Manager of Traffic Safety Services, P.O. Box 189, Albany, New York 12201–0189
Transportation of hazardous materials is subject to special restrictions plus 49 CFR part 397 of the Federal Motor Carrier Safety Regulations.

A tractor used in the operation of a double shall be capable of hauling the maximum weight at a speed of not less than 40 miles per hour on all portions of the Turnpike.
PERMIT: A special permit is required if the vehicle is over 102 inches wide, 14 feet high, or 65 feet in length including overhang. Tractor-semitrailer-semitrailer combinations require a permit if over 75 feet in length, excluding an allowed 3-foot front overhang and a 4-foot rear overhang. For vehicles over 120 inches wide, 14 feet high, or 80 feet long or if any unit of the combination vehicle is over 60 feet in length, travel is restricted to daylight hours Monday through noon Saturday, except holidays and the day before and after holidays. Operators are restricted to daylight driving if the load overhang is more than 4 feet. A “Long Double Trailer Permit” issued by the OTC is required for operation of doubles in excess of 90 feet in length. Towing units and coupling devices shall have sufficient structural strength to ensure safe operation. Vehicles and coupling devices shall be so designed, constructed, and installed in a double as to ensure that any towed vehicles when traveling on a level, smooth paved surface will follow in the path of the towing vehicle without shifting or swerving more than 3 inches to either side of the path of the towing vehicle when the latter is moving in a straight line. Vehicle coupling devices and brakes shall meet the requirements of the Ohio Public Utilities Commission and Federal Motor Carrier Safety Regulations. The distance between the rearmost axle of a semitrailer and the front axle of the next semitrailer in a coupled double unit shall not exceed 12 feet 6 inches. In no event shall the distance between the semitrailers coupled in a double exceed 9 feet. Double and triple trailer combinations must be equipped with adequate, properly maintained spray-suppressant mud flaps on all axles except the steering axle. In the event that the gross weights of the trailers vary by more than 20 percent, they shall be coupled according to their gross weights with the heavier trailer forward. A minimum distance of 500 feet shall be maintained between double units and/or triple units except when overtaking and passing another vehicle. A double shall remain in the right-hand, outside lane except when passing or when emergency or work-zone conditions exist. When, in the opinion of the OTC, the weather conditions are such that operation of a double is inadvisable, the OTC will notify the permittee that travel is prohibited for a certain period of time.
Class A and B explosives; Class A poisons; and Class 1, 2, and 3 radioactive material cannot be transported in double trailer combinations. Other hazardous materials may be transported in one trailer of a double. The hazardous materials should be placed in the front trailer unless doing so will result in the second trailer weighing more than the first trailer.
ACCESS: Tandem trailer units shall not leave the Turnpike right-of-way and shall be assembled and disassembled only in designated areas located at Exits 4, 7, 10, 11, 13, 14, and 16.

Distance measured to nearest foot; when exactly one-half foot, take next larger number.
DRIVER: The driver must have a commercial driver's license with the appropriate endorsement.
VEHICLE: For a combination which includes a truck tractor and two trailing units, the lead trailing unit (semitrailer) may be up to 40 feet long. The second trailing unit may be up to 35 feet long. However, the primary control is the total cargo-carrying distance which has a maximum length of 68 feet. Any towed vehicles in a combination must be equipped with safety chains or cables to prevent the towbar from dropping to the ground in the event the coupling fails. The chains or cables must have sufficient strength to control the towed vehicle in the event the coupling device fails and must be attached with no more slack than necessary to permit proper turning. However, this requirement does not apply to a fifth-wheel coupling if the upper and lower halves of the fifth wheel must be manually released before they can be separated.
PERMIT: A permit is required for operation if the gross combination weight exceeds 80,000 pounds. A fee is charged. Permitted movements must have the lighter trailing unit placed to the rear, and use splash and spray devices when operating in rainy weather. Movement is not allowed when road surfaces are hazardous due to ice or snow, or when other atmospheric conditions make travel unsafe.
ACCESS: As allowed by the Oregon DOT.

The weight on single axles or tandem axles spaced 40 inches or less apart may not exceed 20,000 pounds. Tandem axles spaced more than 40 inches but 96 inches or less may not exceed 34,000 pounds. Two consecutive sets of tandem axles may carry a gross load of 34,000 pounds each, provided the overall distance between the first and last axles of the tandems is 36 feet or more. The weight on the steering axle may not exceed 600 pounds per inch of tire width.
For combinations with a cargo-carrying length greater than 81.5 feet the following additional regulations also apply. The weight on all axles (other than the steering axle) may not exceed 500 pounds per inch of tire width. Lift axles and belly axles are not considered load-carrying axles and will not count when determining allowable vehicle weight.
DRIVER: The driver must have a commercial driver's license with the appropriate endorsement.
VEHICLE: For all combinations, a semitrailer or trailer may neither be longer than nor weigh 3,000 pounds more than the trailer located immediately in front of it. Towbars longer than 19 feet must be flagged during daylight hours and lighted at night.
For combinations with a cargo-carrying length of 81.5 feet or less, neither trailer may exceed 45 feet, including load overhang. Vehicles may be 12 feet wide when hauling baled feed during daylight hours.
For combinations with a cargo-carrying length over 81.5 feet long, neither trailer may exceed 48 feet, including load overhang. Loading the rear of the trailer heavier than the front is not allowed. All axles except the steering axle require dual tires. Axles spaced 8 feet or less apart must weigh within 500 pounds of each other. The trailer hitch offset may not exceed 6 feet. The maximum effective rear trailer overhang may not exceed 35 percent of the trailer's wheelbase. The power unit must have sufficient power to maintain 40 miles per hour. A “LONG LOAD” sign measuring 18 inches high by 7 feet long with black on yellow lettering 10 inches high is required on the rear. Offtracking is limited to 8.75 feet for a turning radius of 161 feet.
Offtracking Formula = 161 - [1612 - (L12 + L22 + L32 + L42 + L52 + L62 + L72 + L82 )]1/2
Note: L1 through L8 are measurements between points of articulation or vehicle pivot points. Squared dimensions to stinger steer points of articulation are negative. For two trailing unit combinations where at least one trailer is 45 feet long or longer, all the dimensions used to calculate offtracking must be written in the “Permit Restriction” area of the permit along with the offtracking value derived from the calculation.
PERMIT: For combinations with a cargo-carrying length of 81.5 feet or less, a single-trip permit is required for movement on the Interstate System if the gross vehicle weight exceeds 80,000 pounds. An annual or single-trip permit is required for hauling baled feed over 102 inches wide.
For combinations with a cargo-carrying length greater than 81.5 feet, a single-trip permit is required for all movements. Operations must be discontinued when roads are slippery due to moisture, visibility must be good, and wind conditions must not cause trailer whip or sway.
For all combinations, a fee is charged for any permit.
ACCESS: For combinations with a cargo-carrying length of 81.5 feet or less, access is Statewide off the NN unless restricted by the South Dakota DOT.
For combinations with a cargo-carrying length greater than 81.5 feet, access to operating routes must be approved by the South Dakota DOT.
ROUTES: Combinations with a cargo-carrying length of 81.5 feet or less may use all NN routes. Combinations with a cargo-carrying length over 81.5 feet, are restricted to the Interstate System and:

OPERATIONAL CONDITIONS:
WEIGHT: Weight limits are as follows:
Single axle: 20,000 pounds
Tandem axle: 34,000 pounds
Gross weight: 129,000 pounds
Vehicles must comply with the Federal Bridge Formula
Tire loading on vehicles requiring an overweight or oversize permit shall not exceed 500 pounds per inch of tire width for tires 11 inches wide and greater, and 450 pounds per inch of tire width for tires less than 11 inches wide as designated by the tire manufacturer on the side wall of the tire. Tire loading on vehicles not requiring an overweight or oversize permit shall not exceed 600 pounds per inch of tire width as designated by the tire manufacturer on the sidewall.
DRIVER: The driver must have a commercial driver's license with the appropriate endorsement. Carriers must certify that their drivers have a safe driving record and have passed a road test administered by a qualified safety supervisor.
VEHICLE: While in transit, no trailer shall be positioned ahead of another trailer which carries an appreciably heavier load. An empty trailer shall not precede a loaded trailer. Vehicles shall be powered to operate on level terrain at speeds compatible with other traffic. They must be able to maintain a minimum speed of 20 miles per hour under normal operating conditions on any grade of 5 percent or less over which the combination is operated and be able to resume a speed of 20 miles per hour after stopping on any such grade, except in extreme weather conditions.
Oversize signs are required on vehicles in excess of 75 feet in length on two-lane highways.
A heavy-duty fifth wheel is required. All fifth wheels must be clean and lubricated with a light-duty grease prior to each trip. The fifth wheel must be located in a position which provides adequate stability. Pick-up plates must be of equal strength to the fifth wheel. The kingpin must be of a solid type and permanently fastened. Screw-out or folding-type kingpins are prohibited.
All hitch connections must be of a no-slack type, preferably a power-actuated ram. Air-actuated hitches which are isolated from the primary air transmission system are recommended.
The drawbar length should be the practical minimum consistent with the clearances required between trailers for turning and backing maneuvers.
Axles must be those designed for the width of the body.
All braking systems must comply with State and Federal requirements. In addition, fast air transmission and release valves must be provided on all semitrailer and converter-dolly axles. A brake force limiting valve, sometimes called a “slippery road” valve, may be provided on the steering axle. Anti-sail type mud flaps are recommended.
The use of single tires on any combination vehicle requiring an overweight or oversize permit shall not be allowed on single axles. A single axle is defined as one having more than 8 feet between it and the nearest axle or group of axles on the vehicle.
When traveling on a level, smooth paved surface, the trailing units must follow in the path of the towing vehicle without shifting or swerving more than 3 inches to either side when the towing vehicle is moving in a straight line. Each combination shall maintain a minimum distance of 500 feet from another commercial vehicle traveling in the same direction on the same highway. Loads shall be securely fastened to the transporter with material and devices of sufficient strength to prevent the load from becoming loose, detached, dangerously displaced, or in any manner a hazard to other highway users. The components of the load shall be reinforced or bound securely in advance of travel to prevent debris from being blown off the unit and endangering the safety of the traveling public. Any debris from the special permit vehicle deposited on the highway shall be removed by the permittee.
Bodily injury and property damage insurance is required before a special Transportation Permit will be issued.
In the event any claim arises against the State of Utah, Utah Department of Transportation, Utah Highway Patrol, or their employees from the operation granted under the permit, the permittee shall agree to indemnify and hold harmless each of them from such claim.
PERMIT: Permits must be purchased. The Utah DOT Motor Carrier Safety Division will, on submission of an LCV permit request, assign an investigator to perform an audit on the carrier, which must have an established safety program that is in compliance with the Federal Motor Carrier Safety Regulations (49 CFR parts 387–399), the Federal Hazardous Materials Regulations (49 CFR parts 171–178), and a “Satisfactory” safety rating. The request must show a travel plan for the operation of the vehicles. Permits are subject to Highway Patrol supervision and permitted vehicles may be subject to temporary delays or removed from the highways when necessary during hazardous road, weather, or traffic conditions. The permit will be cancelled without refund if violated. Expiration dates cannot be extended except for reasons beyond the control of the permittee, including adverse weather. Permits are void if defaced, modified, or obliterated. Lost or destroyed permits cannot be duplicated and are not transferable.
ACCESS: Routes approved by the Utah DOT plus local delivery destination travel on two-lane roads.
ROUTES: For combinations with a cargo-carrying length of 85 feet or less, all NN routes. Combinations with a cargo-carrying length over 85 feet are restricted to the following NN routes:

Appendix D to Part 658—Devices That Are Excluded From Measurement of the Length or Width of a Commercial Motor Vehicle
top
The following devices are excluded from measurement of the length or width of a commercial motor vehicle, as long as they do not carry property and do not exceed the dimensional limitations included in §658.16. This list is not exhaustive.
1. All devices at the front of a semitrailer or trailer including, but not limited to, the following:
(a) A device at the front of a trailer chassis to secure containers and prevent movement in transit;
(b) A front coupler device on a semitrailer or trailer used in road and rail intermodal operations;
(c) Aerodynamic devices, air deflector;
(d) Air compressor;
(e) Certificate holder (manifest box);
(f) Door vent hardware;
(g) Electrical connector;
(h) Gladhand;
(i) Handhold;
(j) Hazardous materials placards and holders;
(k) Heater;
(l) Ladder;
(m) Non-load carrying tie-down devices on automobile transporters;
(n) Pickup plate lip;
(o) Pump offline on tank trailer;
(p) Refrigeration unit;
(q) Removable bulkhead;
(r) Removable stakes;
(s) Stabilizing jack (anti-nosedive device);
(t) Stake pockets;
(u) Step;
(v) Tarp basket;
(w) Tire carrier; and
(x) Uppercoupler.
2. Devices excluded from length measurement at the rear of a semitrailer or trailer including, but not limited to, the following:
(a) Handhold;
(b) Hazardous materials placards and holders;
(c) Ladder;
(d) Pintle hook;
(e) Removable stakes;
(f) Splash and spray suppression device;
(g) Stake pockets; and
(h) Step.
3. Devices excluded from width determination, not to exceed 3 inches from the side of the vehicle including, but not limited to, the following:
(a) Corner caps;
(b) Hazardous materials placards and holders;
(c) Lift pads for trailer on flatcar (piggyback) operation;
(d) Rain gutters;
(e) Rear and side door hinges and their protective hardware;
(f) Side marker lamps;
(g) Structural reinforcement for side doors or intermodal operation (limited to 1 inch from the side within the 3 inch maximum extension);
(h) Tarping systems for open-top trailers;
(i) Movable devices to enclose the cargo area of flatbed semitrailers or trailers, usually called tarping systems, where no component part of the system extends more than 3 inches from the sides or back of the vehicle when the vehicle is in operation. This exclusion applies to all component parts of tarping systems, including the transverse structure at the front of the vehicle to which the sliding walls and roof of the tarp mechanism are attached, provided the structure is not also intended or designed to comply with 49 CFR 393.106, which requires a headerboard strong enough to prevent cargo from penetrating or crushing the cab; the transverse structure may be up to 108 inches wide if properly centered so that neither side extends more than 3 inches beyond the structural edge of the vehicle. Also excluded from measurement are side rails running the length of the vehicle and rear doors, provided the only function of the latter, like that of the transverse structure at the front of the vehicle, is to seal the cargo area and anchor the sliding walls and roof. On the other hand, a headerboard designed to comply with 49 CFR 393.106 is load bearing and thus limited to 102 inches in width. However, the “wings” designed to close the gap between such a headerboard and the movable walls and roof of a tarping system are width exclusive, provided they are add-on pieces designed to bear only the load of the tarping system itself and are not integral parts of the load-bearing headerboard structure;
(j) Tie-down assembly on platform trailers;
(k) Wall variation from true flat; and
(l) Weevil pins and sockets on low-bed trailers.
