WE ARE NOT A PERMIT SERVICE NOR DO WE ARRANGE PERMITS FOR CARRIERS. THIS IS STRICTLY JUST FOR INFORMATIONAL PURPOSES. WE DO NOT ENSURE THE ACCURACY OF THE BELOW INFORMATION SO BE SURE TO READ YOUR PERMIT SHEETS CAREFULLY!
PERMITS: Arizona oversize permits are valid for four days. Drivers have the option of purchasing permits at most Ports of Entry.
OPERATING TIME: Daylight hours, (one-half hour before sunrise to one-half hour after sunset). Loads/vehicles not over 10′ wide or 14′-6″ high or not over 10′ rear overhang are allowed continuous travel. Loads not over 16′ wide, 16′ high, 120′ long and 250,000 pounds may travel on Interstate and specified state routes at night, from 3:00 am to 12:00 noon on weekends (except on holiday weekends and in curfew areas), but this must be requested when permit is ordered and must be stated on the permit. Note that loads over 11′ wide will be required to have one escort to travel from 3 a.m. to noon on weekends, and loads 15′ high and over will need escort with height pole.
RESTRICTED TRAVEL: No OD or OW loads allowed on I-17, I-10 and SR 60 within city limits of greater Phoenix area, or I-10 or I-19 within city limits of greater Tucson area between hours of 7:00 am – 9:00 am and 4:00 pm – 6:00 pm weekdays. Local “Courtesy Permit”/route approval is required for OD travel within Phoenix and Tucson.
57′ trailer on Interstate
Non-designated roads, 65′ overall for over 53′ semi-trailer
Overhang: 3′ front, 6′ rear.
Weight: 80,000 Gross
Single – 20,000

ROUTINE PERMIT LIMITS
Tandem – 46,000*
Tridem – 51,450–53,974*

*(Tandem and Tridem weights may vary depending on axle spacing’s, and axle width. For example, a tridem with 9′ of axle spacing (4′-6″ + 4′-6″) and 8′ axle width gets 51,450).
Note: A “Class C Tridem Permit” can now be obtained to allow 59,168 pounds at 9′ of Tridem axle spacing (57,960 at 8′, 60,000 at 10′). However, this is only for travel on Interstates 10, 19 and 40, and for the portions of SR68 and US93 connecting I-40 and the Nevada line. Any other (including detour) routes will disqualify you.
Over 14′ wide, 16′ high, 120′ long and 250,000 requires a “Class C”. A route survey may be required.
over 120′ – one or more escorts.
Overhang: Front or Rear over 20′ – one escort.
over 14’– 1 or more escorts.
Some restricted routes require two escorts over 12′ wide and a few for over 10′ wide.
Height: over 16′ – one or more escorts.
MISCELLANEOUS: Bulldozer blades and arms over 14′ wide (measured at right angles to the trailer axis) shall be detached and hauled in a manner to not create a safety hazard. Dozer blades shorter than 14′ wide may be hauled without being detached provided the dozer is firmly supported. If buckets, blades, counterweights, etc., are easy to remove, they must be removed, but can be hauled with the load. Blade can be detached and hauled with the dozer on same trailer if the load would be overweight with or without the blade, but it must be stated on the permit. On wide loads, side mirrors must extend far enough to avoid view being blocked by the load.
SIGNS, FLAGS & LIGHTS: All overwidth vehicles or loads exceeding 9′ in width shall display “Oversize Load” signs. All overwidth loads and vehicles must be flagged with red flags 12″ square or larger on extremities. Any front or rear overhang must be flagged or lighted. Up to 10′ overhang may travel at night, but must be lit and flagged. There are no sign or flag requirements for overheight only or overweight only loads.
Note on Overweight Permits in AZ: Arizona scales expect permit weights to be very close to actual weights and dimensions. You can buy the permit at the scales to avoid problems, or else make sure you are ordering accurate weights!
