OVERSIZE AND OVERWEIGHT PERMITS
The maximum legal vehicle dimensions, loaded or unloaded, that may be operated on Utah highways without special permits:
Height: 14’ measured from level road surface to top of load vehicle
Width: 8’ 6” with or without load. Measured from outside to outside of widest extremities, excluding appurtenant devices.
Length: Semi-Trailer 53’, Double trailer combinations 61’. More lengths in Table 1 of PDF
Oversize and overweight vehicles and loads must obtain a permit before operating within the State of Utah.
BRIDGES AND WEIGHING
Interstate bridges are designed to support a wide variety of vehicles and their loads. To protect the integrity of the bridges, Bridge Formula weight limits were developed.
Currently, the Federal single-axle Interstate weight limit is 20,000 pounds. The tandem-axle weight limit is 34,000 pounds. Use the bridge formula to calculate the weight of your motor carrier to determine what you can legally haul to avoid an overweight citation.
