, on any highway if the vehicle or combination of vehicles exceeds in size or weight or gross loaded weight the maximum limitation specified by law for that size, weight and gross loaded weight unless the person or owner is authorized to drive, move, stop or park the vehicle or combination of vehicles by a special permit issued by the proper public authority. 2. If the Department of Transportation or a local law enforcement agency determines that an emergency exists, the Department or the local law enforcement agency may authorize a person to drive, move, stop or park a vehicle or combination of vehicles without obtaining a special permit pursuant to subsection 1. Such an authorization may be given orally and may, if requested by a local law enforcement agency or a public safety agency, include driving or moving the vehicle or combination of vehicles to and from the site of the emergency. If a person receives such an authorization, he shall, on the next business day after receiving the authorization, obtain a special permit pursuant to subsection 1. 3. This section does not apply to: (a) Fire apparatus, highway machinery or snowplows temporarily moved upon a highway. (b) A farm tractor or other implement of husbandry temporarily moved upon a highway other than an interstate highway or a controlled-access highway. (Added to NRS by 1969, 1507; A 2001, 1507; 2005, 72) NRS 484.738 Height of vehicle: Maximum heights with load; exception; unlawful acts. 1. Except as otherwise provided in subsections 2, 3 and 4, a vehicle must not be operated on any highway of this State if its height, including any load, exceeds 14 feet measured from the surface on which the vehicle stands. 2. The maximum permissible height of a load of baled hay is 15 feet. 3. The Department of Transportation shall issue a continuing permit, upon application, to the operator of a vehicle whose height without load exceeds the limit imposed by subsection 1 if the vehicle was registered and in operation on the highway of this State on April 15, 1973. Any such permit must provide only for the operation of the vehicle over those portions of the highways of this State over which it was customarily operated on April 15, 1973, and until it is replaced by another vehicle. 4. It is unlawful to operate a vehicle governed by any of the provisions of subsection 1, 2 or 3 over any portion of a highway where the free clearance of any structure or encroachment is less than the actual height of the vehicle and load. (Added to NRS by 1973, 441; A 1979, 1807) NRS 484.7385 Height of vehicle: Maximum ground clearance; exceptions. 1. A motor vehicle must not be operated on any highway of this State if the lowest portion of its body, as measured from the surface on which the vehicle stands, exceeds, for passenger cars, 24 inches, and for a truck or other motor vehicle having manufacturer’s gross vehicle weight rating: (a) Of 4,500 pounds or less, 28 inches. (b) Of more than 4,500 pounds but less than 7,501 pounds, 30 inches. (c) Of 7,501 pounds but less than 10,001 pounds, 32 inches. 2. The measurement taken to determine compliance with this section must be taken from level ground to a portion of the body or parts attached to the body which have not been added or altered from the manufacturer’s original body design. 3. This section does not apply to a motor vehicle which: (a) Was manufactured before 1935; or (b) Has a manufacturer’s gross vehicle weight rating of 10,001 pounds or more. (Added to NRS by 1987, 1472) NRS 484.739 Length of vehicle: Restrictions; special permit; exceptions. 1. Except as otherwise provided in subsection 2, the length of a bus may not exceed 45 feet and the length of a motortruck may not exceed 40 feet. 2. A passenger bus which has three or more axles and two sections joined together by an articulated joint with a trailer which is equipped with a mechanically steered rear axle may not exceed a length of 65 feet. 3. Except as otherwise provided in subsections 4, 7 and 9, no combination of vehicles, including any attachments thereto coupled together, may exceed a length of 70 feet. 4. The Department of Transportation, by regulation, shall provide for the operation of combinations of vehicles in excess of 70 feet in length. The regulations must establish standards for the operation of such vehicles which must be consistent with their safe operation upon the public highways and with the provisions of 23 C.F.R. § 658.23. Such standards must include: (a) Types and number of vehicles to be permitted in combination; (b) Horsepower of a motortruck; (c) Operating speeds; (d) Braking ability; and (e) Driver qualifications. The operation of such vehicles is not permitted on highways where, in the opinion of the Department of Transportation, their use would be inconsistent with the public safety because of a narrow roadway, excessive grades, extreme curvature or vehicular congestion. 5. Combinations of vehicles operated under the provisions of subsection 4 may, after obtaining a special permit issued at the discretion of, and in accordance with procedures established by, the Department of Transportation, carry loads not to exceed the values set forth in the following formula: W=500 [LN/(N-1) + 12N + 36], wherein: (a) W equals the maximum load in pounds carried on any group of two or more consecutive axles computed to the nearest 500 pounds; (b) L equals the distance in feet between the extremes of any group of two or more consecutive axles; and (c) N equals the number of axles in the group under consideration. The distance between axles must be measured to the nearest foot. If a fraction is exactly one-half foot, the next largest whole number must be used. The permits may be restricted in such manner as the Department of Transportation considers necessary and may, at the option of the Department, be cancelled without notice. No such permits may be issued for operation on any highway where that operation would prevent this State from receiving federal money for highway purposes. 6. Upon approving an application for a permit to operate combinations of vehicles pursuant to subsection 5, the Department of Transportation shall withhold issuance of the permit until the applicant has furnished proof of compliance with the provisions of NRS 706.531. 7. The load upon any motor vehicle operated alone, or the load upon any combination of vehicles, must not extend beyond the front or the rear of the vehicle or combination of vehicles for a distance of more than 10 feet, or a total of 10 feet both to the front or the rear, and a combination of vehicles and load thereon may not exceed a total of 75 feet without having secured a permit pursuant to subsection 4 or NRS 484.737. The provisions of this subsection do not apply to the booms or masts of shovels, cranes or water well drilling and servicing equipment carried upon a vehicle if: (a) The booms or masts do not extend by a distance greater than two-thirds of the wheelbase beyond the front tires of the vehicle. (b) The projecting structure or attachments thereto are securely held in place to prevent dropping or swaying. (c) No part of the structure which extends beyond the front tires is less than 7 feet from the roadway. (d) The driver’s vision is not impaired by the projecting or supporting structure. 8. Lights and other warning devices which are required to be mounted on a vehicle pursuant to this chapter must not be included in determining the length of a vehicle or combination of vehicles and the load thereon. 9. This section does not apply to: (a) Vehicles used by a public utility for the transportation of poles; (b) A combination of vehicles consisting of a truck-tractor drawing a semitrailer that does not exceed
