Routine trucking permit limits:

Length: 120’
Overhang:  3’ front or 6’ rear
Weight:  250,000 maximum. Single axle; 28,000 lbs, tandem axles, tridum axles, and quadem axles. Depends upon the axle spacings and tire size. Trunnion: 60,000. Gross Weight: 5 Axles – 104,000; 6 Axles – 108,000; 7 Axles 117,000. The weights depend upon the number of tires combined with the overall distance between each of the axles. Spacings on axles are tricky in this state. The Arizona DOT permits office will consider a number or factors but primarily bridges. If weights are excessive and trailer capabilities are even close to short of maxing out forget it. Pavement structural and stress testing and results will govern your overall capabilities.

Note maximum speed is set at 55 mph for all oversize/overweight shipments.

  1. I have a flatbed truck with a rear hitch towing a 32′ fifth wheel trailer on I 10 from Nogales to Tucson. the load is in reducible and not over height or width it overhangs the back of the trailer by 7′ I have oversize banners front and rear and am under 54′ overall length.
    do I need a permit to travel during the day?

    • We’re so sorry about the delay Deb and certain you have found your answer. Your post got lost in spam posts. We deleted them all and once the dust cleared there you were. Sorry about that. The answer should be on this page. What is the amount of legal overhang in the state of AZ? 3′ in the front and 6′ in the rear so if you are 7′ then yep, you need a permit.

  2. Why is it oversize at 11 foot have to travel at 55 mph. Seems to me that makes us more if a danger than if we run with the main flow of traffic. To me that is impeding traffic

    • Mendy the states set these laws based on years of research. They may not be perfect but that’s what we have to work with. 11′ wide however is considerably wide in relation to the road. Some shipments may be more stable than others. For instance a boat trailer vs a semi trailer. If a wheel bearing goes out on a cheap boat trailer which happens a lot it would be better for all if it happened at a lower speed. Just my two cents but hey, don’t shoot the messenger 🙂

  3. Shelly, thank you so much for correcting us on the main phone number for the Arizona permits division of the DOT office. We have updated the changes!
