Wyoming ATV laws split cleanly in two: any ATV ridden on the state’s designated off-road trails needs a $15 annual ORV decal, and any ATV ridden on public roads must be titled and registered as a multipurpose vehicle, insured, and operated by a licensed driver. Everything else, including equipment, age limits, helmets, and penalties, flows from which of those two categories you’re in, and sometimes both apply to the same machine.
The $15 Trail Decal for Off-Road Riding
Every ATV used on Wyoming’s designated off-road recreational vehicle trails has to carry a trail user registration decal, usually called an ORV permit. It costs $15 and is valid for one calendar year.1Justia. Wyoming Code 31-2-703 – Required User Registration Fee; Disposition of Fees; Duties of Department of State Parks and Cultural Resources You buy it through a registration selling agent appointed by the Wyoming Department of State Parks and Cultural Resources, and the numbered decal has to be displayed on the vehicle.2Justia. Wyoming Code 31-2-702 – Registration Selling Agents; Application for Trail User Registration Decal; Affidavit Required if Vehicle Serial Number Not Visible; Penalty
Residents and non-residents pay the same $15. Wyoming does not recognize ORV registrations from other states, so if you’re hauling a quad in from Colorado or Montana, buy a Wyoming decal before you ride. The decal only covers designated trail use. It does not stand in for road registration.
Making an ATV Street-Legal
To ride on public streets or highways, your ATV has to be registered as a multipurpose vehicle. Wyoming defines an MPV as a motor vehicle designed for four or more wheels, with an unladen weight between 300 and 3,000 pounds, and a permanent upright seat or saddle at least 24 inches from the ground.3Wyoming Department of Transportation. Multipurpose Vehicles Most ATVs and side-by-sides fit.
Every MPV owner must get a title for the vehicle whether they ride on roads or not. Registration and plates are required only if you actually operate on public streets or highways.4Wyoming Department of Transportation. Multipurpose Vehicle Frequently Asked Questions Fees are set at the county level. Registering as an MPV does not replace the $15 ORV decal if you also ride designated trails.
One hard limit: MPVs cannot be operated on interstate highways. On other public roads, if your MPV can’t reach the posted speed limit, you must stay on the far right edge of the roadway and display either a reflectorized flag or a slow-moving vehicle emblem. MPVs designed for speeds under 25 mph always need a slow-moving vehicle emblem.5Justia. Wyoming Code 31-5-124 – Off-Road Recreational Vehicles; Multipurpose Vehicles; Limitation on Use; Equipment
Anyone driving an MPV on public roads needs a valid driver’s license. Instructional (learner’s) permit holders can operate one, but every restriction on that permit still applies, including the requirement to have a licensed adult present.4Wyoming Department of Transportation.

Required Equipment
What your machine needs on it depends on where it’s running.
On Designated Trails
Every ATV on a public street, road, or trail has to have an adequate braking device operated by hand or foot. Between a half hour after sunset and a half hour before sunrise, you need functioning headlights and tail lamps.6Justia. Wyoming Code 31-5-1601 – Operation on Highways On state or federal lands, two more items are mandatory: an approved spark arrestor and a muffler keeping noise at or below 102 decibels measured at 20 inches in a stationary test.7Wyoming Legislature. Off-Road Recreational Vehicles Requirements Spark arrestors exist to prevent wildfires, and riding without one on federal land can draw both state and federal citations.
On Public Roads as an MPV
The bar is higher for road use, and the exact list depends on vehicle width. For an MPV wider than 50 inches: two headlights (one per side), two tail lamps, two rear reflectors, two stop lamps, a muffler, brakes, at least one mirror, and a horn. For an MPV 50 inches or narrower: one headlight, one tail lamp, one rear reflector, one stop lamp, a muffler, brakes, at least one mirror, and a horn.8Wyoming Department of Transportation. Multipurpose Vehicle Information Checklist
Turn signals are not on the state’s MPV equipment list, which surprises a lot of riders. Local ordinances can add to the state checklist, so check with your county before you assume it’s final.
Age and License Rules
Because road use requires a driver’s license, and Wyoming issues its first license at 16, anyone under 16 effectively cannot ride an ATV on streets or highways. For limited agricultural road crossings, a minor operating an ORV must have a valid driver’s license with a motorcycle endorsement.5Justia. Wyoming Code 31-5-124 – Off-Road Recreational Vehicles; Multipurpose Vehicles; Limitation on Use; Equipment
For off-road trail riding, state statute sets no specific minimum age. Federal land managers like the U.S. Forest Service and BLM can impose their own age and supervision rules on lands they administer, and the Wyoming State Trails Program encourages youth participation in ATV safety training based on ATV Safety Institute guidelines. If you’re putting a kid on a machine, verify the rules for the specific land you’ll be riding before you go.
Helmets and Safety Gear
Adult ATV riders in Wyoming are not required to wear helmets. Riders and passengers under 18 must wear an approved helmet whenever operating on roads under the ORV provisions.9Wyoming State Parks. ORV Requirements That rule tracks road use for agricultural operations under W.S. 31-5-124.
There is no statewide mandate for goggles, gloves, or other protective equipment. The Wyoming State Trails Program advises all operators and passengers to wear helmets regardless of age.
Where You Can Ride
Wyoming has an enormous amount of public land open to ATVs, but public land does not mean ride anywhere. Access depends on who manages the land and what designations apply.
National forests allow ATVs only on trails and roads specifically designated for motorized use. Seasonal closures are common, typically to protect wildlife during calving or nesting and to prevent trail damage in spring mud season. The Bureau of Land Management generally permits ATV use on existing roads and trails but prohibits cross-country travel in ecologically sensitive areas. State parks maintain designated ORV riding areas with their own rules, and some state trust lands used for grazing or conservation restrict motorized access entirely. County and municipal governments can add further restrictions, so what’s legal in one county may draw a citation in the next.
Roads and travel routes enrolled in the state ORV program require only the $15 decal. If you ride on a public road that is not designated for ORV travel and is not enrolled in the program, your ATV must be street-legal with a license plate and the full MPV equipment: headlamp, tail light, brake light, red rear reflector, horn, and a left-hand rearview mirror.9Wyoming State Parks. ORV Requirements This is where a lot of riders get crossways with the law, assuming the ORV decal covers any road they encounter.
Trespassing on Private Land
Wyoming prints a trespass warning right on every ORV decal. Trespassing on private property while riding an off-road vehicle is a criminal offense punishable by up to six months in jail, a fine of up to $750, or both.10Justia. Wyoming Code 31-2-704 – Payment of Fees; Issuance of Numbered Decal; Trespass Warning Printed on Decal In country where public and private boundaries aren’t always obvious from a trail, a GPS unit with land ownership data is cheap compared to the citation.
Insurance
Wyoming does not require insurance for ATVs used only off-road. Once you register as an MPV for street use, you must carry minimum liability coverage of $25,000 per person for bodily injury, $50,000 per accident for bodily injury involving two or more people, and $20,000 for property damage.11Justia. Wyoming Code 31-9-405 – Liability Policy Defined Letting that coverage lapse can bring fines and registration suspension.
Even for trail-only riders, insurance is worth a look. Standard auto policies usually exclude off-road vehicles unless you specifically add coverage, so if you damage property or injure someone on a trail, you’re personally on the hook. Some private landowners and organized events require proof of insurance as a condition of access, and lenders almost always require it on financed machines.
Penalties
Operating an ATV on a designated trail without the ORV decal, or violating trail operation rules, is a misdemeanor carrying a fine of up to $100.2Justia. Wyoming Code 31-2-702 – Registration Selling Agents; Application for Trail User Registration Decal; Affidavit Required if Vehicle Serial Number Not Visible; Penalty That’s a lot compared to the $15 the permit costs, and enforcement patrols popular riding areas.
Riding on public roads without proper MPV registration, plates, and required equipment can bring citations. Specific fines vary by county and the violation. Repeat problems can affect your ability to register vehicles down the line.
Wyoming’s DUI statute applies to any vehicle, and ATVs are not an exception, whether you’re on a trail or a road. A first offense is a misdemeanor punishable by up to six months in jail, a fine of up to $750, or both, with driver’s license suspension and, depending on blood alcohol level, a six-month ignition interlock requirement on your vehicles. Penalties climb with repeat offenses, and a fourth DUI within ten years becomes a felony.12Justia. Wyoming Code 31-5-233 – Driving or Having Control of Vehicle While Under Influence of Intoxicating Liquor or Controlled Substances Being on an ATV rather than in a car does not soften any of it.
