2021 Arizona state shipping laws, regulations, rules and limitations for oversize and overweight trucking on state highways and roads.
Please share your expertise of Arizona state DOT trucking regulations with other visitors below.
As per the state of Arizona please read the following:
“The Arizona Department of Transportation in cooperation with state representatives, industry, the Department of Public Safety and local law enforcement personnel work in collaboration to update and amend oversize and overweight special permit rules containing special permit requirements, restrictions and allowances for transporting oversize and overweight vehicles and loads on highways under the jurisdiction of the Department. This is a council established in statute and makes up the Over-dimensional Permit Council.
These rules detail the eligibility, application and use requirements for a variety of permits the Department currently issues to commercial motor carriers for transporting vehicles or vehicle and load combinations exceeding the maximum size or weight limitations provided by statute.
Each special permit provided by the Department under these rules is specifically authorized by statute. The oversize and overweight special permits issued under these rules are that each permittee issued a particular class of permit is subject to the same activities, practices, requirements and restrictions applicable to that permit type. The statutes additionally provide authority for issuance, conditions, restrictions, approvals and fees.”

Do I need a trucking permit? Legal load limits.
Arizona maximum load limits until a trucking permit is required:
Length: Anything over 65 feet in length overall requires a permit on non-designated highways.
Overhang: 3 feet in the front and 6 feet off of the rear of trailer maximum (make sure your route is approved for overhang as there are location variations).
Weight: 80,000 pounds overall (GVW), 12,000 pounds on steer axle.
Width: 8 feet and 6 inches wide maximum.
Height: 14 feet maximum on interstates and 13 feet and 6 inches in height on secondary roads.
Routine heavy haul and oversize trucking permits in Arizona.
These maximum dimensions/weights are considered routine oversize or heavy-haul trucking permits in Arizona:
Length: 120 feet maximum or proceed to super load section.
Weight: 250,000 pounds maximum (Class C if over or see superloads). Single axle is 28,000 pounds maximum. All tandem, tridum, trunnion and quadem axle configurations depend on axle spacings and tire sizes. Gross weight maximums: 5 axles is 104,000 pounds, 6 axles is 108,000 pounds, 7 axles is 117,000 pounds. The permissible maximum weights depend on the number of tires combined with the overall distance between each of the axles. Spacings on axles are a little bit tricky in this state. The Arizona DOT permits office will consider a number or factors but it’s primarily about the bridges which could require a route survey if extreme weights are involved. If weights are excessive and trailer capabilities are even close to short of maxing out, forget it! Pavement, structural and stress testing results will govern your overall permissible capabilities.
Width: 14 feet wide maximum or file under super load.
Height: 16 tall maximum or file under super load.
Overhang: 3 feet of front or 6 feet off of the rear or any configuration that is in excess of 75 feet. They could require you to use a stretch trailer before allowing you to proceed under super load provisions.
Notes: These above routinely permitted shipments will need to be filed as class “A” permits. Class A permits are anything under 120 feet in length, 14 feet in width, 16 feet in height or under 250,000 pounds overall. Maximum speed is set at 55 mph for all oversize/overweight shipments.
Super load information for Arizona.

Once it is approved you will see pending/approved/refused when you log in. The fee is $30 for class C shipments that are no greater than 18 feet in height and/or width and 80,000 pounds. Shipments that are over 80,000 pounds are $90. Shipments that are over 18 feet in height and width, but not over 80,000 pounds, are $40. For shipments that are greater than 18 feet in height and width and/or 80,000 pounds are $100. Typical class C permits are only valid for 4 working days unless otherwise specified. In order to obtain a class C permit extension beyond the 4 day working allowance you must either have inclement weather issues or equipment breakdown issues.
ADOT ePRO payment screen if requesting 3 a.m. or weekend movement for loads up to 16 feet wide and 16 feet high. The entire route must be designated for night movement, weekend movement or both or it will be denied.
