Garbage / Waste / Recycling: A vehicle used by an authorized waste, garbage or recycling carrier can cost 22,000 pounds on a single axle and 40,000 pounds on a tandem axle on each non-interstate highway (Nev. Rev. Stat. § 484D.640). Divisible loads: The Department of Transportation may issue excess weight permits authorizing the applicant to drive a vehicle or combination of vehicles carrying a divisible load exceeding the state weight limits for three weight classes, up to 84,000 lbs., up to 112,000 lbs. and up to 129,000 lbs GVW, provided the state`s transition formula is not exceeded. These permits are available for different periods of up to 1 year (Utah Code Ann. §72-7-406[8]). The gross weight of vehicles in regular operation (operation without a special permit) is regulated by the State Bridge Formula (adopted FBF).
The deck formula adopted by the state allows a maximum of 80,000 lbs on a 5-axle vehicle, provided the vehicle complies with FBF. See Figure 10 for a summary of weight determinations in Arizona in regular operation (Ariz. Rev. Stat. Ann. §28-1100). Tow truck: A vehicle that is towed freely from the road surface with an assembly of axles is exempt from state weight restrictions when driving on state or additional highways (Del. Code Ann. tit.
21, § 4501 [h]). Agricultural and forestry products: If deemed necessary by the Minister due to an emergency, unusual circumstances, natural disaster or disaster, a permit may be granted for agricultural or forestry products in their natural state, allowing a total loaded weight of up to 100,000 pounds, although the boundaries of the Crown axis continue to apply (La. Rev. §32:387[C][2]).65 The maximum gross weight that can be transferred to any combination of units is limited by the maximum gross weight that can be carried on each unit and its axles. The maximum gross weight of the tractor and the first semi-trailer is regulated by this formula: 35,000 lbs plus 1,000 lbs per foot between the centre of the foremost axle of the tractor and the centre of the rearmost axle of the first semi-trailer. Boat trailers: Government weight restrictions do not apply to oversized boat lifts or hydraulic trailers owned by a marina or watercraft dealer and used exclusively for commercial vessel storage (Mich. Comp. Laws Ann. §257.716 [2]). Many state laws include clauses that limit state weight limits to prevent federal funds from being withheld due to non-compliance with federal regulations.
States enforce compliance with these federal compliance clauses in a variety of ways.12 Many states require legislators or the State Department, which oversees vehicle weight regulations, to increase limits if federal law changes or if they are notified that they are not complying with federal law. Some states tie their limits directly to increases or decreases in federal weight limits, while others simply nullify any provision that would compromise the use of federal funds for their state. The laws governing the size and weight of trucks in the state of Maine can be found in Me. Rev. Stat. 29-A, §§ 2351 et seq. (available on the state website under www.mainelegislature.org/legis/statutes/29-A/title29-Ach21sec0.html). Additional provisions on excess weight permits can be found in Me. Rev.
Stat. Ann. tit. 29-A, §§2380 et seq. For more information on weight restriction laws, see the Bureau of Motor Vehicles document: www1.maine.gov/sos/bmv/commercial/Commercial%20Vehicle%20Laws%20&%20Regulations%20(June%206.%202012).pdf. On non-interstate highways, maximum weight limits are ranked according to the number of axles in a vehicle: two-axle vehicles are limited to 34,000 lbs., three-axle vehicles are limited to 54,000 lbs., four-axle vehicles (and five-axle monobloc vehicles) are limited to 69,000 lbs. Five or more axles are limited to 80,000 lbs and a combination of a three-axle tractor and a three-axle semi-trailer is limited to 100,000 lbs. limited.
Maine uses the specified maximum values and calculates lower limits for certain center distances (measured between extreme axles without a steered axle): Laws regarding truck size and weight in the state of Arizona can be found in Ariz. Rev. Stat. Ann. §§28-1100 ff. (available on the state website under www.azleg.gov/ArizonaRevisedStatutes.asp?Title=28). State regulations for overweight permits are available in Arizona. Code §§R17-6-101 ff. Road Machinery: Road machinery or equipment is exempt from South Carolina`s laws regarding size, weight, and load (S.C.
Code Ann. §56-5-4020). Raw milk: The Illinois Department of Transportation (IDOT) may issue special permits for continuous limited operation that authorize the transportation of raw milk shipments beyond state weight limits, provided no axle exceeds 20,000 pounds and gross weight does not exceed 80,000 pounds. These permits do not permit travel on interstate highways (Ill. Rev. Stat. ch. 625, §5/15-301[o]).

These are some three-, four- and five-axle vehicles. They shall not permit the driving of vehicles with a total weight exceeding 80,000; However, they allow operation at levels that exceed the bridge formula or axle limits. [ Return to footnote 142 referrer. ] Sealed Containers: In order to provide access to the Port of Baltimore for international cargo, the Secretary of Transportation has the authority, if necessary, to issue regulations for the licensing of overweight vehicles carrying only international goods manifested in sealed shipping containers on a semi-trailer. These vehicles can carry 22,400 lbs on a single axle, 44,000 lbs on tandem axles or 90,000 lbs. They may operate only on portions of interstate and state highway systems designated by the Secretary of State in cooperation with the United States Department of Transportation, or on the shortest convenient route approved by the Secretary between that designated highway and a truck terminal; Port; other place of departure or destination; or (within 1 mile of the designated highway) facilities for food, fuel, repair, or recreation (Md. Transportation Code Ann. §24-113.1).78 Certain motor vehicles registered with the State Tax Commission on or before April 24, 1974, are considered vehicles that have an additional 12-foot distance on interstate highways. This provision applies to vehicles whose distance between the outer axles is greater than 29 feet but less than 40 feet and whose total weight does not exceed 72,000 lbs on four axles or whose gross permissible laden weight does not exceed 73,280 lbs on five axles (Miss Code Ann.
§ 63-5-34). Forest Products: Any vehicle transporting forest products in its natural state may operate 37,000 pounds per tandem axle, except on the interstate system (La. Rev. Stat. Ann. §32:386 [D]). If the governor declares a culture situation an emergency, this special permit is valid from September 1 to September 31. December for vehicles transporting otherwise eligible agricultural raw materials, provided that the weight does not exceed the normal limits by 20 per cent (Ill. Rev.
Stat. ch. 625, §5/15-301[e] [e-1]).

Certain vehicles subject to Canadian weight restrictions are allowed to cross the border: The Commissioner of Transport, in consultation with the Department of Public Safety and the Department of State, is authorized to authorize certain commercial vehicles with a maximum authorized weight limit in Canada to travel from the Canada-U.S. border to Calais at Baileyville. from the Canada-U.S. border in Madawaska to a paper mill in Madawaska and from the Canada-U.S. border in Van Buren to a railway station in Van Buren. Vehicles may travel from the Canada-U.S. border under the following conditions: Livestock: Vehicles transporting livestock are exempt from wheel, tire, axle or axle group load capacity restrictions if the excess weight is caused by a shift in livestock weight (N.D.
