Utah Oversize & Overweight Permits for Heavy Haul
Utah permit rules, legal limits and escort triggers, and how we book heavy haul carriers for moves in and through the state.
Quick answer
Do I need a permit to move an oversize load in Utah?
A permit is needed once a load goes past 8 ft 6 in wide, 14 ft high or 80,000 lbs. UDOT's Motor Carrier Division issues permits online or at ports of entry: $30 for an oversize single trip and $60 for oversize and overweight up to 125,000 lbs, with a per-mile charge above that. Single trip permits run up to 96 hours.

Heavy haul and oversize freight in Utah
Utah's heavy freight funnels through the Wasatch Front: I-15 runs from St. George through Salt Lake City and Ogden to Idaho, I-80 crosses from Nevada through Salt Lake City and Parleys Canyon toward Wyoming, and I-70 and US-6 cross the east. Mining equipment, data center and construction projects along the Wasatch Front, and loads moving between California and the Mountain West keep heavy haul trucks busy. We book carriers for moves within Utah or through it.
Utah's rules turn on two things: the Wasatch Front and the canyons. Loads over 12 ft wide stay off the highways around Salt Lake City, Ogden and northern Utah County at weekday rush hours, and canyon routes such as Provo, Logan and Little Cottonwood carry far tighter limits than the Interstates. We check UDOT's list of restricted secondary highways before quoting any move that leaves the freeway.
What are the legal size and weight limits in Utah?
Under the oversize load regulations in Utah, a load above any of these limits needs a state oversize or overweight permit.
| Width | 8 ft 6 in |
|---|---|
| Height | 14 ft |
| Semitrailer length | 53 ft |
| Gross weight | 80,000 lbs |
| Single axle | 20,000 lbs |
| Tandem axle | 34,000 lbs |
Limits are set by Utah Code 72-7-402 and 72-7-404. Utah's legal height is 14 ft, and longer combination vehicles run only by permit on approved freeway routes.
Who issues Utah oversize permits?
UDOT's Motor Carrier Division issues permits through its online permit system or at any of its eight ports of entry, which sell single trip, semi-annual and annual permits. A single trip permit runs up to 96 continuous hours, and permits must be bought before entering Utah except at three border ports on I-15 and I-80.
Loads over 17 ft wide, 17 ft 6 in high or 300,000 lbs go to the division's superload team, are processed only on weekdays, and can take up to 14 days because each UDOT region's permit office reviews the route.

Worked example: per-mile charges on heavy Utah loads
UDOT's own fee table prices a 150,000 lb load traveling 150 miles at $130 under the per-mile formula, and a 300,000 lb load going 50 miles at the same $130. The charge is capped at $540 however heavy or long the move, and escorts are paid separately.

Seasonal weight limits in Utah
Utah has no frost law. Any highway authority can restrict weights after an engineering inspection finds weather damage, effective while signs are posted, and UDOT can put seasonal limits on individual permits. Winter is handled through the weather and traction rules: larger permitted loads stop on snow or ice, and when UDOT activates traction requirements, heavy vehicles need traction devices on their drive tires.
