Arizona oversize permit rules
What Arizona charges for a single-trip OS/OW permit, the limits that trigger one, and the escort thresholds — read from the state’s own publication. This rule has been in effect since 2026-06-24; we last read the source on 2026-07-06.
Oversize permit
$15–$40
The load has to fit inside a tier on every dimension at once — width and height and length. Exceed any one of them and it falls to the next tier up.
Overweight permit
From $75
Priced per load rather than at a flat rate.
A load that is both oversize and overweight pays this fee only, not both.
+ $20 Permigo service fee per permit, state fees at cost.
Legal limits
Exceed any one of these in Arizona and you need a permit for this state.

Arizona prices a single-trip permit as by dimensional envelope. The load has to fit inside a tier on every dimension at once — width and height and length. Exceed any one of them and it falls to the next tier up.
| Band | State fee |
|---|---|
| Within 14'0" wide × 16'0" high × 120'0" long | $15 |
| Within 18'0" wide × 18'0" high | $30 |
| Anything larger | $40 |
Escort requirements
Thresholds by road class. Where two classes differ, the road you are actually on governs.
