Utah Oversize & Overweight Permits filed with UDOT for you, 24/7

In Utah, a load over 8 ft 6 in wide, 14 ft high or 80,000 lbs needs a permit from the UDOT Motor Carrier Division, and it has to be in hand before the truck enters Utah, except at the St. George, Echo and Wendover ports of entry. Over 125,000 lbs, only single-trip permits are issued. Send us the load and route: our permit desk quotes the price and files it for you.

Routes and road rules

Where Utah routes add their own rules

The state line, the Wasatch Front and a handful of secondary highways change what a permitted load can do.

  1. Entering Utah

    The permit has to be issued before the truck enters Utah. The exceptions are loads entering at the St. George port on northbound I-15, Echo on westbound I-80 and Wendover on eastbound I-80.

    Any other crossing:The permit comes first, then the state line.

  2. Salt Lake, Davis, Weber and northern Utah County

    Loads over 10 ft wide, 105 ft long or 14 ft 6 in high stay off the road 6–9 a.m. and 3:30–6 p.m. on weekdays, including I-80 mileposts 101–139 and I-84 west of milepost 91.

    SR-201:From I-80 to 7200 West it counts as a freeway for escort rules.

What we check before filing in Utah

  1. Is the load over 125,000 lbs?

    Above 125,000 lbs Utah issues single-trip permits only, so a semi-annual or annual permit will not cover it. We file each move on its own permit.

  2. Lead time for police and superloads

    Utah Highway Patrol escorts are booked at least 48 hours ahead, superloads need 48 hours of authorization and regional authorization can take two weeks. We file early enough to keep your pickup date.

  3. Curfew and holiday hours

    Wide loads lose the weekday rush hours on the Wasatch Front, and holidays start at 2 p.m. the day before. We plan departures around both before you commit to a delivery.
