Oversize & Overweight Provisions

Utah Administrative Rule R909-2-8

General Oversize or Overweight Provisions

Obtaining Oversize/Overweight Permits

Before moving a vehicle or load which exceeds legal dimensions as outlined in Utah Administrative Rule R909-2-4 “Legal Size Vehicle Dimensions” a permit must be obtained and carried in the vehicle for inspection by law enforcement personnel.

The permit may be in paper or electronic format.

The appropriate permit for oversize vehicles and loads must be obtained prior to operating within the State of Utah, except when entering on I-15 (St. George Port of Entry), Westbound I-80 (Echo Port of Entry) and Eastbound I 80 (Wendover Port of Entry).

Prior to operation in the State of Utah, permits may be purchased online with a major credit card at:

Permits are issued on a single trip, semi-annual or annual basis.

Because of additional processing requirements, loads exceeding 17′ 6″ in height, 17′ in width, or have a gross weight over 300,000 lbs. will only be processed during Monday through Friday from 8 a.m. to 5 p.m. (Mountain Standard Time), and may take up to 14 Days for approval.

Dual Lane Trailers


Overweight/Oversize Loads using dual lane trailers (over 10 feet wide) that do not pass bridge validation require clearance from the UDOT Structures Division. Review times are dependent upon the length of the route and the number of structures crossed. This clearance can take a minimum of 14 business days, or longer, and should be applied for prior to purchasing the permit.
UDOT Structures Division approvals are for a single trip only. Carriers utilizing the same configurations/equipment are required to obtain a new approval prior to each move by the UDOT Structures Division to ensure that ongoing inspections and maintenance have not caused a change in bridge condition since the prior move. The approval process on repeat configurations/equipment and routes should take reduced time than the original clearance.
For more information on this process and/or assistance using the online bridging calculator, contact Motor Carrier Customer Service at (801) 965-4892.
