The Wyoming Highway Patrol (WHP) issues oversize and overweight permits under WYDOT Rules Chapter 5, Size and Weight Limitations of Vehicles. These are the numbers we plan every Wyoming load with. Run your exact load and route through our permit tool to see every state on the trip.

Escorts
Wyoming escort requirements
Wyoming sets escorts by width, length and rear overhang, and by the type of highway.
Wyoming escorts by load size
Official sources linked| Load | Escorts |
|---|---|
| 14'W or wider, two lane highways | One front and one rear (WYDOT Rules Chapter 5, Wyoming Highway Patrol, commercial carrier rules) |
| 110'L or longer, two lane highways | One front and one rear (WYDOT Rules Chapter 5, Wyoming Highway Patrol, commercial carrier rules) |
| Any part of the load left of the centerline, two lane highways | One front and one rear (WYDOT Rules Chapter 5, Wyoming Highway Patrol, commercial carrier rules) |
| 15'W or wider, interstates and four lane divided highways | One escort (WYDOT Rules Chapter 5, Wyoming Highway Patrol, commercial carrier rules) |
| Rear overhang of 25' or more | One rear escort on all highways (WYDOT Rules Chapter 5) |
Escort rules come from WYDOT Rules Chapter 5, Section 8, and the Wyoming Highway Patrol escort rules. The Highway Patrol leaves escorts for height, and for length on interstates, to the approving authority, so the permit sets them.
