Arizona Oversize/Overweight Permit (6-AZ-a)

Information current as of 2024
In Arizona, a developer may need an oversize/overweight permit from the Arizona Department of Transportation (ADOT) to transport oversized loads for a project. Ariz. Rev. Stat. § 28-1103; Ariz. Rev. Stat. § 28-1104. “Non-reducible” load applies to any load or vehicles exceeding an applicable length or weight limit that if separated into smaller loads would:
  • Compromise the intended use of the vehicle;
  • Destroy the value of the load or vehicle;
  • Require more than eight workhours to dismantle using appropriate equipment.

Ariz. Admin. Code § R17-6-101(B)

A permit is required if the width, height, or weight of the vehicle exceeds any of the following dimensions:

  • Maximum Width is 8.5 feet;
  • Maximum Height is 14 feet;
  • Maximum Length for a Straight Truck is 40 feet;
  • Maximum Length for a Truck Tractor: Semi-Trailer combination on the National Highway Network is 57.5 feet;
  • Maximum Length Truck Tractor: Semi-Trailer combination on all other Highways and State Highway systems is 65 feet;
  • Maximum Weight for a Steering axle is 20,000 pounds;
  • Maximum Weight for a Single axle is 20,000 pounds;
  • Maximum Weight for a Towaway Trailer Transporter combination is 26,000 pounds; or
  • Maximum Weight for a Five axles or more Vehicle is 80,000 pounds.

Ariz. Admin. Code § R17-6-102

ADOT permits are only valid for state and interstate highways, so developers will need to check with local jurisdictions for authorization to travel on roadways that are not under ADOT jurisdiction. Oversized permits can be issued for single-trips, 30-day or annual periods.

The ADOT has the authority to regulate transportation of oversized loads on state and interstate highways pursuant to Ariz. Rev. Stat. § 28-1103 and Ariz. Rev. Stat. § 28-1104.
