Wyoming is ATV country as most of the terrain is rough and rugged and just made for your ATV. Wyoming has some unique statutes that apply to ATVers and you should be thoroughly aware of them before riding your ATV.
Your ATV must be 50 inches or less in width and have an unladen weight of 900-lbs or less and have a minimum of three low pressure tires. This fortunately accommodates most modern ATVs and almost ATV you purchase today will more than meet these base requirements for riding your ATV on the roads in Wyoming.
Wyoming has a State ORV Program which has worked in conjunction with the Forest Service, BLM, the Wyoming Game and Fish Department, the Office of State Lands and the Wyoming Division of State Parks and Historic Sites have worked to identify not only roads, but also trails and open areas for you to ride your ATV upon.
The rules for driving your ATV on roads is if the vehicle has a motor vehicle license plate it may be operated upon any roadway in Wyoming and an ORV permit is NOT required. If the vehicle displays only the Wyoming ORV Permit, then it may be operated only upon those road ways enrolled in the State ORV Program. This applies to both residents and non-residents of Wyoming.
Also, you must have a valid driving license in order to operate your ATV or ORV on any of these roads or trails regardless of whether or not you are enrolled in the ORV Program.
While the following are not rules or regulations for riding your ATV in Wyoming, they do ask that you adhere the following ethics when you ride:
1. Do not stir up, rally or drive game animals or birds with your ATV.
2. Do not cross shoulders or embankments maintained by a government entity on your ATV.
3. Do not leave any designated ATV trail on any federally managed lands.
4. Do not unreasonably damage the land, wildlife, or vegetative resources with your ATV.
Knowing these simple rules and good common sense will make for a great time riding your ATV in Wyoming.
