Oversize/Overweight Permits

The Class A oversize/overweight permits are issued for vehicle and load combinations that are within specific size and weight limits. The load must be nonreducible. The Class A permit is issued for a single trip or 30 days. Class A permits are issued only for travel on state routes.

Permits for use of other than state routes are procured from the proper local authority. Please see our routing contacts below for more information. For the city of Phoenix, see the Phoenix Police Department's oversize/overweight load permits.
