Wyoming Rules on National Forest Ground
Riding an ATV or UTV on Wyoming National Forest ground takes more than finding a track on a map. You need the right Wyoming permit, a route open to your machine, and a plan for closures and land-specific rules. Here’s how to check those details before you unload, and what a permit does—and does not—allow.
Start With the Route, Not Just the Forest
A National Forest is not one continuous riding area. Roads and trails can have different rules depending on their location, season, width limits, and the type of vehicle allowed. A track that looks rideable on a phone map may be closed to motor vehicles, open only to certain classes of machines, or subject to a seasonal restriction.
The key question is not simply, “Can I ride in this forest?” It is, “Is this specific route open to my machine on the day I plan to ride?”
Before your trip, check the current travel-management information for the forest and district you plan to visit. A Motor Vehicle Use Map, often called an MVUM, identifies routes open to motorized use and may show vehicle or seasonal restrictions. Follow the map’s instructions and check for newer closure notices or signs. Conditions and restrictions can change, so a map saved from a previous trip may no longer be reliable.
For an overview of the routes available across the state, see Wyoming’s Enrolled Roads and Trails. For help interpreting the land manager’s map, Reading a Wyoming Travel Management Map explains what to look for.
Match the route to your machine
An open route is not necessarily open to every ATV or UTV. Some trails have width restrictions, and some routes are designated for particular vehicle types. A UTV that is wider than a trail limit may need to stay on a wider route, even if the rest of the group is riding a narrower trail nearby.
Check the machine’s actual width and compare it with the restrictions shown for your chosen route. Do not rely on a model name or a general idea of what counts as a “side-by-side.” If you are unsure how a route’s width limit applies, ask the managing district before you ride. Wyoming’s 50-Inch Trail Limit provides more context on width-restricted routes.
Treat signs and closure notices seriously
A sign at the trailhead or along the route can give important, route-specific information. If a sign says closed, do not assume that an older map or a visible tire track overrides it. Temporary closures may be put in place for safety, maintenance, fire conditions, wildlife, or other management reasons.
If a map and an on-the-ground sign appear to conflict, pause and contact the local land manager rather than guessing. A posted closure can apply to just one segment, but riding around it on an unapproved track is not a safe workaround. Use a route that is clearly open.
Get the Wyoming Permit, Then Check Reciprocity
Wyoming’s off-road vehicle permit is a separate requirement from permission to use a particular National Forest route. A permit does not turn a closed road into an open one, replace a land manager’s authorization, or make a machine street legal.
Check the current Wyoming permit rules for your machine and intended use before riding. The rules can depend on where the machine will be operated and whether the route is part of the state’s enrolled system. Federal land status does not, by itself, answer whether a Wyoming permit is required. Confirm the requirement for your planned route with the appropriate state program or land manager. Wyoming ORV Permits Explained covers the permit system and the questions riders should settle before a trip.
Do not assume a permit, plate, or sticker from another state will satisfy Wyoming’s requirement. Wyoming does not generally treat another state’s registration as a substitute for its own ORV permit. If you are visiting, check Wyoming ORV Reciprocity Rules and Buying a Wyoming Permit as a Visitor before you head to the forest.
| What you have | What it may cover | What it does not establish |
|---|---|---|
| Wyoming ORV permit | The state permit requirement for eligible use, as applicable | That a particular forest route is open |
| Out-of-state registration or sticker | Registration or permission under the issuing jurisdiction | That Wyoming accepts it in place of a Wyoming permit |
| National Forest map | Route designations and restrictions shown on that map | That no newer closure or sign applies |
| A road-legal plate | Road registration, subject to applicable rules | Permission to ride every forest road or trail |
| A rental agreement | Permission to use the rented machine under the rental terms | That the machine’s permit or route access is settled |
Check the decal on a rented or borrowed machine
If you are renting or borrowing an ATV or UTV, ask who is responsible for the Wyoming permit and how you can confirm it is valid. Do not assume that a rental machine’s permit covers every rider, every route, or every type of use. Ask the rental company to clarify what the machine is authorized for and what restrictions apply.
If you are riding a machine owned by someone else, check the decal and the applicable permit rules before leaving the staging area. A receipt or the owner’s assurance may not answer whether the specific machine is covered. See Wyoming Rules for a Rented Machine for questions to settle before taking a rental onto public land.
Follow Forest Rules for Equipment, Noise, and Route Use
The permit is only one part of trip planning. Forest Service rules, route designations, and applicable state requirements can also affect how and where you ride. The details may differ between forests and routes, so verify the rules for your destination rather than treating one trip’s requirements as statewide.
Use only routes open to motor vehicles
Stay on the road or trail that is designated open. Do not cut across meadows, switchbacks, streambanks, or open ground to save time or get around an obstacle. Even a short detour can damage vegetation and soil, and cross-country travel may be prohibited.
This also applies when a route is rough, blocked, or crowded. If you cannot continue safely, turn around or use an authorized alternative. A visible track is not proof of legal access: it could be an old route, an unauthorized shortcut, or a path made by vehicles that should not have been there.
Check width and vehicle restrictions before unloading
Confirm that the entire route is suitable for your machine, not just the first section. A wider UTV may fit on the road to a trailhead but be prohibited on a narrow trail beyond it. If your group has different vehicle sizes, choose a route that all machines may use or arrange a lawful alternative for the machines that cannot continue.
Check for limits applying to vehicle width, class, or other features. If the information is unclear, contact the district office and describe the machine you plan to bring. A route being open to motorized vehicles does not necessarily mean it is open to every ATV and UTV.
Maintain required equipment
Public-land rules may require specific equipment or set operating standards, including requirements related to spark arresters or sound. Check the current rules for the forest and route you will use; do not assume that a machine’s factory equipment automatically meets every applicable requirement.
Keep the machine in sound working condition and avoid modifications that create excessive noise. Carrying a tool kit or spare parts can help with common breakdowns, but it does not make an otherwise noncompliant machine acceptable. For more on equipment expectations, see Wyoming Spark Arrester and Sound Rules and Spark Arresters on Wyoming Trails.
Respect gates, signs, and other users
Follow posted instructions, close gates after passing through when they are meant to be closed, and leave barriers in place. Gates may protect livestock or manage access; their presence does not give riders permission to leave a route or enter land that is closed.
Yield appropriately to other trail users and slow down where sight lines are limited. Dust, noise, and speed can affect people on foot, cyclists, and horseback riders. A courteous pass and a controlled pace are especially important on narrow trails, around blind corners, and near trailheads. Yielding to Horses on a Wyoming Trail has more on sharing routes safely.
Plan for Seasonal Closures and Changing Conditions
National Forest access can change through the year. Snow, spring thaw, wildlife concerns, fire danger, maintenance, and other conditions can close routes or limit use. A route that was open during one visit may be closed on a later trip.
Check current information close to your departure date, then look again for signs when you arrive. This is particularly important when traveling to a high-elevation area or planning to ride early or late in the season. A trailhead may be accessible while the route beyond it remains closed.
Fire restrictions can affect the whole trip
Dry conditions may bring fire restrictions that affect camping, cooking, vehicle use, or access. Restrictions vary, and a fire rule can apply even when the riding route itself remains open. Check the current notices for the forest and any adjacent lands you will use.
Carry only the fuel and equipment you need, secure fuel containers for transport, and avoid parking or stopping where a hot machine could create a fire hazard. If restrictions or conditions change, follow the current instructions rather than relying on what was allowed when you planned the trip.
Weather and surface conditions matter
Forest roads can become difficult or unsafe after rain, snowmelt, or a rapid weather change. Muddy ground is especially vulnerable to damage from repeated vehicle traffic. If a route is deteriorating or your machine is leaving deep ruts, turn back instead of forcing a pass.
Wyoming weather can change quickly, particularly at elevation. Check the forecast, carry clothing for colder and wetter conditions than you expect, and make a turnaround plan. Let someone know where you are going and when you expect to return. Cell service may be limited, so do not rely on a phone connection as your only way to get help.
Keep the route information available
Download or carry the current travel-management map before leaving an area with reliable service. A paper map can be useful if a phone battery runs down, an app fails, or a route is hard to identify. Make sure the map covers the area you intend to ride and includes the relevant route restrictions.
Use maps as a planning and navigation tool, not as a substitute for signs or current closure information. If you are uncertain about a junction, stop in a safe place and confirm your location before continuing. Do not take an unmarked spur simply because it appears to lead toward your destination.
A Practical Pre-Ride Checklist
A few checks before departure can prevent a wasted trip or an avoidable citation. Set aside time for them before loading the machine, rather than trying to sort everything out at the trailhead.
- Identify the exact forest, district, and route. “Riding in the Bighorns” or “going into the Medicine Bow” is not specific enough to confirm access.
- Check the current route map. Confirm that each road or trail is designated open to motorized use and suitable for your machine.
- Look for seasonal and temporary closures. Check land-manager notices close to your trip and obey posted signs on site.
- Confirm the Wyoming permit requirement. Do not assume an out-of-state sticker, plate, or rental arrangement settles the question.
- Verify the machine’s limits. Compare its width and type with the route’s restrictions.
- Review equipment and sound rules. Make sure the machine meets applicable requirements before you arrive.
- Plan for changing weather and limited service. Carry route information offline, bring suitable supplies, and set a turnaround time.
- Ask when something is unclear. Contact the relevant district or permit program rather than treating uncertainty as permission.

Frequently Asked Questions
Does a Wyoming ORV permit let me ride anywhere in a National Forest?
No. A permit addresses a state permit requirement where it applies. It does not open a closed route, authorize cross-country travel, or override a route’s vehicle restrictions. Check the current forest map, closure notices, and signs.
Does an out-of-state permit or registration count in Wyoming?
Do not assume it does. Wyoming generally requires its own ORV permit where applicable, and out-of-state decals or registrations are not a reliable substitute. Confirm the rules before your trip, especially if you are visiting from another state.
Can a UTV use any forest road that is open to motor vehicles?
Not necessarily. A road or trail may have width or vehicle-class limits. Compare the route restrictions with your machine’s actual specifications and check the full route, including any narrower trail sections.
What should I do if the map and a sign disagree?
Treat a closure sign as a reason to stop and verify access. Do not ride past it based on an older map or another rider’s tracks. Contact the local land manager if the current status is unclear.
Can I use a Forest Service road to reach a trail?
Only if the connecting road is open to your machine and riding there is permitted. Confirm that both the access road and the trail are designated for your vehicle type, and check for closures along the full route.
