Arizona · Oversize & Overweight

Arizona Oversize & Overweight Permits filed with ADOT for you, 24/7

In Arizona, a load over 8 ft 6 in wide, 14 ft high or 80,000 lbs needs an ADOT permit. Non-reducible loads up to 14 ft wide, 16 ft high, 120 ft long and 250,000 lbs run on a Class A permit; anything bigger is a Class C superload. ADOT covers state highways only, so city streets and tribal roads need their own permits. Send us the load and route: our permit desk quotes the price and files every permit the trip needs.

Which permit you need

Arizona permits for oversize and overweight loads

  1. Up to 14 ft wide, 16 ft high, 120 ft long, 250,000 lbs

    Class A single-trip permit

    One move of a non-reducible load, valid up to 96 hours. If a breakdown or weather stops the move, the permit can be extended once, by up to four days.

  2. Repeat moves within Class A limits

    Class A multiple-trip and annual permits

    The same Class A limits for as many moves as needed over 30 days or a full year.

  3. 30 days or one year

    Envelope permits

    Annual or 30-day permits for oversize loads, or for loads that are both oversize and overweight.

  4. Over 250,000 lbs or any Class A limit

    Class C superload permit

    Single trip only, pre-approved by ADOT's Class C Unit. The load may need an engineering analysis and a route survey before the permit is issued.

Routes and road rules

Where Arizona routes add their own rules

ADOT lists route-specific restrictions in its Table 4. These are the ones that catch loads most often.

  1. I-15 through the Virgin River Gorge

    Mileposts 0 to 15.38 in Arizona's northwest corner. A non-articulated load over 100 ft long needs front and rear escorts plus two law enforcement escorts.

    Law enforcement:Contact Arizona DPS at least 12 hours before the move.

  2. US 60, Queen Creek Tunnel

    Loads 14 to 20 ft high need front and rear escorts plus two law enforcement escorts, and must drive through the center of the tunnel.

    Other tunnels:The I-10 Deck Park Tunnel clears 15 ft 7 in and the SR 80 Mule Pass Tunnel 14 ft.

  3. Phoenix and Tucson freeways

    Weekdays 7–9 a.m. and 4–6 p.m., loads over 10 ft wide stay off I-10, I-17, SR 51, SR 143, SR 202 and US 60 in Phoenix, and off I-10 between Marana and Kolb, I-19, SR 77, SR 86 and SR 210 in Tucson.

    On parts of SR 101, 202 and 24:10–12 ft wide needs a rear escort in those hours; 12–16 ft cannot move.

  4. US 93 and the Hoover Dam bypass

    The Mike O'Callaghan–Pat Tillman Memorial Bridge is permitted by Nevada, not ADOT. A load crossing it needs the Nevada permit too.

    Plan:File both states before the truck reaches the bridge.

Arizona loads

Arizona permits for the loads Arizona hauls

Beside Class A and Class C, ADOT has industry permits and a separate permit for longer combinations.

    A permit type of its own for crane and drilling-rig moves. ADOT issues a separate tridem permit as well.

  2. Recreation

    Recreational vehicle and watercraft permits

    Industry permits written for recreational vehicles and watercraft.

  3. Lake Powell

    Page–Lake Powell houseboat permit

    A dedicated permit for houseboats moving on the Page and Lake Powell route.

  4. Multiple trailers

How it works

Your Arizona permit in three steps

  1. Send the load and route

    Truck, trailer, dimensions, weight, origin and destination. Your fleet details are saved for next time.

  2. We check and file

    Our permit desk checks the Arizona rules for your load and files with ADOT MVD Enforcement & Compliance.

  3. Get your permit

    You get the permit PDF, a written route and an interactive route map to share with the driver.

What we check before filing in Arizona

  1. Table 4 on the day you move

    ADOT changes its route restrictions often, and carriers must check Table 4 daily. A temporary restriction at the US 191 Rock Tunnel turned anything over 8 ft 6 in into a Class C permit. We check the route against Table 4 before filing.

  2. City streets and tribal land

    An ADOT permit ends where the state highway ends. If pickup or delivery sits on a city street or tribal land, that city or tribal nation issues its own permit, and we file it with the ADOT one.

  3. Metro hours and the 3 a.m. start

    Over 10 ft wide, Phoenix, Tucson and Yuma are closed to the load 7–9 a.m. and 4–6 p.m. on weekdays. We time the metro crossing and use the 3 a.m. start on Table 4 routes when the load qualifies.

FAQ

Arizona oversize permit questions

What dimensions put an Arizona load over the legal limit?

Over 8 ft 6 in wide (8 ft on restricted routes), 14 ft high (13 ft 6 in on restricted routes), 3 ft of front or 6 ft of rear overhang, 57 ft 6 in for a semitrailer on the National Network or 53 ft elsewhere, 20,000 lbs on a single axle or 80,000 lbs gross under the bridge formula.

How much does an Arizona oversize permit cost?

It depends on the permit class, size, weight and route, and Class C superloads cost more. Put your route into our permit cost calculator for an estimate, or send us the load and our permit desk quotes the exact price before filing.

How is an Arizona Class A permit different from Class C?

Class A covers non-reducible loads up to 14 ft wide, 16 ft high, 120 ft long and 250,000 lbs, for one trip, 30 days or a year. Past any of those limits the load is Class C: single trip only, pre-approved by ADOT's Class C Unit, sometimes with an engineering analysis and a route survey.

Can escort operators certified in another state work in Arizona?

Yes. Arizona accepts other states' certificates. Escort operators must be certified to CVSA standards and renew at least every four years.

Is night or weekend travel allowed for wide loads in Arizona?

On Table 4 routes, loads 10 to 16 ft wide or up to 16 ft high may run at night and on weekends from 3 a.m., with a rear escort over 11 ft wide and front and rear escorts over 14 ft. Bigger loads move only from half an hour before sunrise to half an hour after sunset.

What hours are Phoenix and Tucson closed to wide loads?

Monday to Friday, 7–9 a.m. and 4–6 p.m., for loads over 10 ft wide, on the listed Phoenix and Tucson freeways. Yuma has the same weekday curfew.
