Wyoming oversize permits are obtained from Ports of Entry by the driver (see phone list at bottom of this page). Driver must call ahead to the Port/Scale at least one hour prior to arrival and obtain a clearance number. Failure to do this will result in up to a $500 fine and 24-hour shutdown. The permit is usually valid for one day or one trip.
One-half hour before sunrise to one-half hour after sunset, including weekends, plus loads not exceeding 10′ wide, and all other dimensions are legal, may travel at night on Interstate highways only with proper lighting.
Holiday travel is usually allowed for loads not requiring escorts, but Ports of Entry are not open, so check with the Port on pre-ordering permit if you wish to run on the holiday.
SEASONAL LOAD RESTRICTIONS: No specific annual restrictions, but they may be imposed as necessary during spring thaw.
The vehicle must have the following characteristics:
Divisible Loads Exceeding 80,000: You can exceed 80,000 gross without a permit on state and Interstate highways as long as you are legal on all axle weights and bridge and you are licensed for at least the amount of your gross weight.
Register for up to 117,000 pounds to permit for that much or more
Loads in excess of these dimensions are considered as superloads.
On Interstate Highways:
On 2-nd Lane Highways:
All oversize loads/vehicles must display Oversize Load on both front and rear. Flags are to be placed on projections extending beyond sides of trailer. Over 4′ of rear overhang must be flagged (daytime) or lighted at night.
