Size, Weight, & Motor Carrier Permitting

Photo of a large load on a trailer being pulled across Interstate 80 in western Utah.

Overweight/Oversize Loads utilizing dual lane trailers (axle widths in excess of 10 feet wide) that do not pass bridge validation require clearance from UDOT Structures Division. Depending upon the length of the route and the number of structures crossed, this clearance may take up to 14 days and should be applied for prior to purchasing your permit.

More information on this process and assistance using the online bridging calculator may be obtained by calling Motor Carrier Customer Service at 801-965-4892.
