Summary:

• In Arizona, continuous travel is allowed for vehicles and loads under 10 feet wide, 14 feet high, and with less than a ten-foot overhang.
• Overwidth vehicles or loads that surpass 9 feet in width must display “Oversize Load” signs and have 12-inch square red flags at their extremities.
• No oversize movement is permitted through the greater Tucson area from 7-9 a.m. and 4-6 p.m., on Interstate 30 between mile markers 137-143, Interstate 40 between mile markers 151-155, or at any place on Interstate 630.

Operating Hours, Restricted Travel, and Holiday Restrictions

Continuous travel is allowed for vehicles and loads that are under 10 feet wide, 14 feet high, and have less than a ten-foot overhang. Oversize loads can move only during daylight hours.

Loads within 16 feet wide, 16 feet high, 120 feet long, and 250,000 pounds are permitted to travel on the interstate and on specified state routes from 3 a.m. until noon on weekends in non-curfew areas, except during holidays. These loads require a permit, and you must state the intention to travel during these times on the permit itself. Within these circumstances, loads over 11 feet wide or 15 feet high must have an escort vehicle.

Permitted vehicles (with or without additional escort vehicles) cannot travel in inclement weather where the movement has been deemed unsafe. Secondary highways are restricted to 40 mph and may be posted for a lesser weight. No overwidth vehicle is allowed to follow another overwidth vehicle at a distance of less than 1,000 feet.

No oversize movement is permitted through the greater Tucson area from 7-9 a.m. and 4-6 p.m., on Interstate 30 between mile markers 137-143, Interstate 40 between mile markers 151-155, or at any place on Interstate 630.

Oversize loads cannot travel on the following holidays: 

• New Year’s Day
• Memorial Day
• Independence Day
• Labor Day
• Thanksgiving Day
• Christmas Day

Signs, Flags, and Lights Requirements

Signs

Overwidth vehicles or loads that surpass 9 feet in width must display “Oversize Load” signs.

Flags

All overwidth vehicles should have red flags that are 12 inches square or larger on their extremities. Vehicles with an overhang up to 10 feet may travel at night, but they must be flagged and lit appropriately.

Lights

Vehicles with an overhang up to 10 feet may travel at night, but they must be flagged and lit appropriately. Any front or rear overhang should have lights illuminating the overhang.

Obtaining a Permit

Single-trip permits are one-use and valid for four days. For all permits, the load must be non-reducible. In addition, 30-day and annual permits are vehicle-specific. These authorizations are issued from the Permit Office and must stay in the vehicle to accompany the annual permit.

Permits can be ordered on the Arizona state website

or by calling the Arizona Motor Vehicle Division at (602) 255-0072.
