[49 FR 23315, June 5, 1984] Editorial Note: For Federal Register www.govinfo.gov. § 658.7 Applicability. 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. (a) The National Network listed in the appendix to this part is available for use by commercial 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. 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. (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 (b) Deletions—Federal-aid primary—other than interstate. Federal Register (c) Requests for deletion—Federal-aid primary—other than interstate. (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. (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 (e) Emergency deletions. Federal Register (f) Exceptions. (g) Restrictions—Federal-aid primary—other than interstate. (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.

(a) No State shall impose a width limitation of more or less than 102 inches, or its approximate metric equivalent, 2.6 meters (102.36 inches) on a vehicle operating on the National Network, except for the State of Hawaii, which is allowed to keep the State's 108-inch width maximum by virtue of section 416(a) of the STAA. (b) The provisions of paragraph (a) of this section do not apply to special mobile equipment as defined in § 658.5. (c) Notwithstanding the provisions of this section or any other provision of law, a State may grant special use permits to motor vehicles, including manufactured housing, that exceed 102 inches in width. [49 FR 23315, June 5, 1984, as amended at 59 FR 30419, June 13, 1994; 67 FR 15110, Mar. 29, 2002; 72 FR 7748, Feb. 20, 2007] § 658.16 Exclusions from length and width determinations. (a) Vehicle components not excluded by law or regulation shall be included in the measurement of the length and width of commercial motor vehicles. (b) The following shall be excluded from either the measured length or width of commercial motor vehicles, as applicable: (1) Rear view mirrors, turn signal lamps, handholds for cab entry/egress, splash and spray suppressant devices, load induced tire bulge; (2) All non-property-carrying devices, or components thereof— (i) At the front of a semitrailer or trailer, or (ii) That do not extend more than 3 inches beyond each side or the rear of the vehicle, or (iii) That do not extend more than 24 inches beyond the rear of the vehicle and are needed for loading or unloading, or (vi) Listed in appendix D to this part; (3) Resilient bumpers that do not extend more than 6 inches beyond the front or rear of the vehicle; (4) Aerodynamic devices that extend a maximum of 5 feet beyond the rear of the vehicle, provided such devices have neither the strength, rigidity nor mass to damage a vehicle, or injure a passenger in a vehicle, that strikes a trailer so equipped from the rear, and provided also that they do not obscure tail lamps, turn signals, marker lamps, identification lamps, or any other required safety devices, such as hazardous materials placards or conspicuity markings; and (5) A fixed step up to 3 inches deep at the front of an existing automobile transporter until April 29, 2005. It will be the responsibility of the operator of the unit to prove that the step existed prior to April 29, 2002. Such proof can be in the form of a work order for equipment modification, a receipt for purchase and installation of the piece, or any similar type of documentation. However, after April 29, 2005, the step shall no longer be excluded from a vehicle's length. (c) Each exclusion allowance is specific and may not be combined with other excluded devices. (d) Measurements are to be made from a point on one side or end of a commercial motor vehicle to the same point on the opposite side or end of the vehicle. [67 FR 15110, Mar. 29, 2002] § 658.17 Weight. (a) The provisions of the section are applicable to the National System of Interstate and Defense Highways and reasonable access thereto. (b) The maximum gross vehicle weight shall be 80,000 pounds except where lower gross vehicle weight is dictated by the bridge formula. (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. (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 over-the-road bus, or 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, 2009. Any State that has enforced, in the period beginning October 6, 1992, and ending November 30, 2005, a single axle weight limitation of 20,000 pounds or greater but less than 24,000 pounds may not enforce a single axle weight limit on these vehicles of less than 24,000 lbs. (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. (n) Any vehicle subject to this subpart that utilizes an auxiliary power or idle reduction technology unit in order to promote reduction of fuel use and emissions because of engine idling, may be allowed up to an additional 400 lbs. total in gross, axle, tandem, or bridge formula weight limits. (1) To be eligible for this exception, the operator of the vehicle must be able to prove: (i) By written certification, the weight of the APU; and (ii) By demonstration or certification, that the idle reduction technology is fully functional at all times. (2) Certification of the weight of the APU must be available to law enforcement officers if the vehicle is found in violation of applicable weight laws. The additional weight allowed cannot exceed 400 lbs. or the weight certified, whichever is less.

(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 28 1/2 (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.

(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. (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 designation 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). Minor 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 FHWA, 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 alternate 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. If the adjustment involves vehicle operating restrictions, the State shall list the restrictions that have been removed or modified. If the adjustment is approved, the FHWA will publish the notice of adjustment, with an expiration date, in the Federal Register. (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 within 30 days after the restriction is effective. The FHWA will publish the restriction in the Federal Register (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.

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. Vehicle Combinations Subject to Pub.

(2)—No maximum weight is established as this vehicle combination is not considered an “LCV” per the ISTEA definition. 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. The following abbreviation convention is used throughout the narrative State-by-State descriptions for the captions OPERATIONAL CONDITIONS, ROUTES, and LEGAL CITATIONS: two letter State abbreviation, dash, “TT” for truck tractor, and 2 or 3 for two or three trailing units. For example, the phrase “Arizona truck tractor and 2 trailing units”, would be noted as “AZ-TT2”; the phrase “Indiana truck tractor and 3 trailing units” would be noted as “IN-TT3”, etc. STATE: ALASKA COMBINATION: Truck tractor and 2 trailing units LENGTH OF THE CARGO-CARRYING UNITS: 95 feet OPERATIONAL CONDITIONS: WEIGHT: DRIVER: VEHICLE: PERMIT: ACCESS: Routes From To AK-1 Anchorage (Potter Weigh Station) Palmer (Palmer-Wasilla Highway Junction).

[59 FR 30422, June 13, 1994, as amended at 60 FR 15215, Mar. 22, 1995; 60 FR 16571, Mar. 31, 1995; 62 FR 10181, Mar. 5, 1997; 63 FR 70653, Dec. 22, 1998; 67 FR 15110, Mar. 29, 2002; 77 FR 32014, May 31, 2012; 83 FR 49488, Oct. 2, 2018; 84 FR 43688, Aug. 22, 2019] Appendix D to Part 658—Devices That Are Excluded From Measurement of the Length or Width of a Commercial Motor Vehicle 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.
