Colorado Permit Rules on Designated Trails

A Colorado OHV permit is easy to mistake for an all-access pass. It isn’t. The permit or registration generally covers the machine’s required paperwork for public-land riding; it does not tell you whether a particular trail is open, wide enough, or legal for your vehicle. This guide explains how the rules work on designated trails and what to check before unloading or setting off.

What a permit does on a designated trail

In Colorado, “designated” matters. A trail is not automatically open to motorized use just because it appears on a map, has tire tracks, or connects to a road. The land manager determines which routes are open to motor vehicles, which vehicle types may use them, and whether seasonal or temporary restrictions apply.

The permit or registration is a separate requirement. It generally shows that an OHV has the required Colorado registration or nonresident permit for use on public lands. It does not grant permission to ride a closed route, cross private land, ignore a seasonal gate, or take a vehicle onto a trail that is too narrow for it.

For most riders, the practical sequence is:

1. Identify the land manager and the route you plan to ride.
2. Confirm that motorized travel is allowed on that route.
3. Check vehicle limits, seasonal dates, closures, and any local rules.
4. Make sure the machine has the right Colorado registration or permit.
5. Display and carry the required documents as directed.
6. Follow signs and closures on the ground, even if a map or app appears to show the route as open.

A permit and a route map solve different problems. The permit addresses the machine’s authorization or registration status. The map and current land-manager information help establish where you may ride. A valid permit cannot make an unauthorized trail legal.

What counts as a designated route

A designated route is one the responsible agency or local authority has identified for motorized use. Depending on the area, it may be called a trail, road, route, or motor vehicle route. The exact term is less important than the official designation and its restrictions.

On federal land, use the relevant route information from the land manager. For Forest Service roads and trails, a Motor Vehicle Use Map can be an important source for vehicle access and seasonal information. On BLM land, check the applicable route map, area rules, and posted restrictions. State, county, and municipal routes may have their own rules and maps.

A route may be open to one type of machine but not another. Restrictions can involve width, vehicle class, or a route’s intended use. A narrow trail suitable for a dirt bike or a machine within a posted width limit may not be legal for a full-size side-by-side. The same area can also contain routes with different rules, so don’t assume that one open trail means every connecting route is open.

For help reading agency maps and seasonal information, see Reading a Colorado Motor Vehicle Use Map and Reading Seasonal Dates on an MVUM. If you are using an app, treat it as a planning tool rather than the final authority. Compare what it shows with current official maps and signs.

A permit is not a trail pass

Riders sometimes hear “you need a permit for the trail” and assume there is one trail-specific fee that gives access. In many cases, the relevant requirement is an OHV registration or permit for riding on public land. Separately, a trailhead, park, recreation area, or special event may have additional rules or charges.

The distinction is useful:

Question	What answers it
Does the machine have the required Colorado paperwork?	Colorado OHV registration or the applicable nonresident permit
Is motorized travel allowed on this particular route?	Current map, route designation, land-manager rules, and signs
Can this machine use the route?	Vehicle-type and width restrictions, plus route-specific limits
Is there a separate area or parking requirement?	The rules for the park, trailhead, recreation area, or local jurisdiction
Is riding allowed today?	Current closures, seasonal dates, fire restrictions, and posted orders

When planning a trip, check each question rather than relying on a single permit, map app, or sticker.

Which Colorado paperwork applies to your machine

Colorado’s basic paperwork path depends partly on where the machine is based and whether it is registered in Colorado. Residents and visitors should not assume that the paperwork they use at home automatically satisfies Colorado’s requirements.

For a Colorado-based OHV, the usual path is Colorado OHV registration. For a visiting machine, a Colorado nonresident OHV permit may be required for public-land riding. A permit’s current terms, validity, eligibility, and display requirements should be confirmed with Colorado Parks and Wildlife before the trip.

The distinction between a vehicle registration and an OHV permit can be confusing, particularly for machines that have plates or paperwork from another state. A machine can be registered elsewhere and still have a Colorado requirement when it is used on Colorado public land. Check the guidance for your exact vehicle and circumstances rather than treating an out-of-state registration as a universal substitute.

Rider or machine situation	What to check before riding
Colorado resident using an OHV on public land	Colorado OHV registration requirements and current display rules
Visitor bringing an ATV, UTV, or dirt bike	Colorado nonresident permit requirements, including how the permit must be displayed
Machine registered in another state	Whether that registration changes or satisfies any Colorado permit requirement; do not assume it does
Plated or street-legal machine entering an OHV route	Permit requirements for that vehicle and the route’s own access rules
Machine used only on private property	Whether public-land paperwork rules apply to the planned use, and whether the property owner allows access
Rental machine	Which paperwork is supplied by the rental business and what remains the rider’s responsibility

For the resident process, start with Registering an OHV in Colorado. Visitors can compare the options in Colorado Non-Resident OHV Permit Explained and Which Colorado Permit an Out-of-State Rider Buys. If the machine has an out-of-state plate, see Why Plated Vehicles Still Need a Colorado Permit and Colorado Rules for Out-of-State Street-Legal Machines.

Out-of-state registration and plates

An out-of-state plate can make a vehicle legal to operate on certain roads, but it does not automatically settle every OHV permit question. Colorado may have a separate requirement for riding a machine on public lands, including designated routes. The exact answer can depend on how the vehicle is classified, the kind of registration it carries, and where it will be operated.

This is where riders can get caught by an assumption. “It’s registered at home” and “it’s legal on this Colorado trail” are not the same statement. Before the trip, ask the relevant agency whether the machine needs a Colorado nonresident permit, and confirm whether the route permits that vehicle type. If it is a plated side-by-side or other vehicle with mixed road and off-highway use, check both the permit question and the route’s access rules.

Do not rely only on a seller’s statement, an old forum post, or the fact that another rider was not stopped. Requirements and local access conditions can differ by area and change over time. Colorado Parks and Wildlife can clarify permit questions; the land manager or local authority can answer route questions.

Permits for borrowed and rented machines

Borrowing a friend’s machine does not necessarily remove the permit requirement. Ask the owner what registration or permit is in place, whether it is valid for the planned use, and whether you can verify the display and paperwork before leaving. A sticker alone may not answer every question, so check the underlying documents when there is any doubt.

With a rental, ask the rental business directly whether the machine’s Colorado paperwork is current and included for the route you plan to ride. Also ask whether the rental is restricted to particular trails or areas. Rental paperwork does not make a route open if the route is closed or unsuitable for that machine.

For broader guidance, see Permits for a Borrowed Machine, Does a Colorado Rental Include the OHV Permit?, and Colorado OHV Rules for First-Time Visitors. If you are taking a vehicle provided by a guide or outfitter, confirm what the operator handles and what you are expected to carry.

How to verify that a designated trail is open to your vehicle

A common planning mistake is checking only the permit and the trail’s name. Before you ride, verify the route itself, the vehicle limits, and the conditions that apply on your planned date. A trail can be legally open but still inappropriate for your machine or group.

Start with the land manager. Identify whether the route is on national forest, BLM, state, county, municipal, or private land. Then find the official map or access information for that jurisdiction. If the route crosses more than one type of land, check each segment. A route may change status at a boundary, and road access rules can differ from trail rules.

Next, look for conditions that may affect access:

• Vehicle type or width: A route may exclude larger machines even when smaller OHVs are allowed.
• Seasonal restrictions: A route may open or close at set times, or remain closed until conditions improve.
• Temporary closures: Fire danger, construction, storm damage, wildlife protection, or trail work may trigger a closure.
• Local ordinances: A county or town may regulate roads differently from the public land next to them.
• Private property: A map line may pass near or through private land; public access should not be assumed.
• One-way or special-use rules: Some routes may have direction, event, or operating restrictions.
• Posted signs: Field signs and closure gates can provide the most immediate notice of a restriction.

A GPS track is not proof of permission. User-submitted tracks may show a route that is now closed, was never open to the public, or is legal only for certain machines. Even an accurate app can lag behind an emergency closure. Use it to navigate only after you have confirmed that the route is open.

Check every part of a route, not just the destination

A route description may name a well-known trail or pass, but reaching it can involve county roads, forest roads, trail connectors, or local streets. Each segment can have separate rules. If you plan to ride from a campground to a trailhead, for instance, the campground’s access road may not have the same status as the trail system itself.

This matters especially when a route passes near a town. Some communities allow OHVs on specified streets, while others restrict or prohibit that use. A trail map might show a connection to town without explaining every local rule. Check the local ordinance and posted signs before riding through. For road-use context, see Which Colorado Roads Allow OHVs and Finding Your Colorado County’s OHV Ordinance.

If you are linking multiple routes, plan the full ride from staging area to return point. Confirm each connector, crossing, and town segment. A legal trail at the far end does not make an illegal road connection acceptable.

Use maps, signs, and current notices together

No single source is perfect for every decision. A practical approach is to compare:

1. The official map or route information for the land manager.
2. Current closure notices and seasonal rules.
3. Signs and gates at the trailhead or junction.
4. Local requirements for any roads or town segments.
5. Your machine’s dimensions and configuration.

If sources appear to conflict, do not treat the most permissive version as the answer. A posted closure or agency order should be taken seriously, even if an older map still shows the route. When the status is unclear, call the responsible office before traveling to the trailhead.

A simple paper copy of your planned route can help when a phone loses service. Keep it current and mark the relevant route numbers, access points, and alternate turnarounds. If you order a waterproof map sleeve or a compact paper map through Amazon, use it as a backup to official route information—not as proof that a trail is open. Save a map offline on your phone as well, but remember that offline maps may not include newly announced restrictions.

Displaying and carrying the required paperwork

Buying the correct permit is only one part of compliance. Follow the current instructions for how it must be displayed, and keep any required registration or permit record available while riding. Requirements can differ between resident registration and a nonresident permit, so do not copy another rider’s setup without checking that it applies to your machine.

A decal should be placed where the official instructions specify and where it remains visible. Avoid covering required information with a protective film, accessory, or mounting device unless the instructions allow it. Clean and dry the mounting surface before applying an adhesive decal, and check that it has not peeled off after washing or dusty rides.

Keep the associated paperwork protected from water and abrasion. A small sealed pouch in a secure, accessible part of the machine can help, provided it does not interfere with controls or safety equipment. A zip document pouch bought through Amazon may be useful for a registration card or permit record, but it should not obscure the decal or replace any required display method.

For machine-specific instructions, see Where to Stick an OHV Decal on a Four-Wheel ATV, OHV Decal Placement on a Side-by-Side, or Colorado Sticker Placement on a Dirt Bike. If a sticker is damaged or missing, check Replacing a Damaged Colorado OHV Decal before your next public-land ride.

Keep the documents easy to find

A ranger or other enforcement officer may ask about the machine’s registration or permit. Keep the relevant record accessible without rummaging through unsecured bags on a trail. If more than one person in a group is carrying documents, make sure each rider knows which machine the paperwork belongs to and where it is stored.

For a group ride, do not assume that one person’s permit covers everyone’s machines. Check the requirements for each machine. If you are organizing several vehicles, make a simple list of machine identifiers, permit status, and the person responsible for each document. A printed checklist kept with the trip plan can prevent a last-minute scramble at the staging area.

A small clear document sleeve from Amazon can make it easier to separate paperwork for multiple machines, especially when a group is traveling in dusty or wet conditions. Label each sleeve clearly and avoid leaving original documents exposed in an unattended vehicle.

Common mistakes and a pre-ride checklist

The mistakes below often come from treating paperwork, route access, and vehicle capability as one issue. They are separate checks, and each can determine whether the ride is legal and manageable.

Common mistakes

• Assuming a permit opens every trail. It does not override route closures, width limits, land boundaries, or town rules.
• Assuming a plate replaces all OHV paperwork. Ask whether the specific machine and use require a Colorado permit.
• Relying on an old map. Seasonal dates and closures can change; confirm the current information.
• Following a track without checking access. A GPS line is not an official authorization.
• Ignoring vehicle width. A route may be open to some OHVs but not a wider UTV or side-by-side.
• Treating a road and a trail as interchangeable. They can have different rules even when connected.
• Assuming a borrowed machine is already covered. Verify the paperwork before riding.
• Continuing past a closure sign because the route looks passable. Physical access does not mean legal access.
• Confusing public-land permits with private-land permission. A permit does not give you the right to cross someone else’s property.
• Assuming a rental company has handled every detail. Confirm what is supplied and where the rental is allowed to go.

For private-property use, the rules may differ from public-land riding, but property permission remains a separate issue. Start with Colorado OHV Registration for Machines Kept on Private Land and Written Permission Before Riding Private Land if your trip includes private property.

A practical pre-ride checklist

Before leaving home or the rental counter, confirm:

• The machine has the required Colorado registration or nonresident permit for the planned use.
• The decal is displayed according to current instructions.
• Required paperwork is available and protected.
• The route is officially designated for motorized travel.
• The route allows your machine’s class and width.
• Seasonal dates and temporary closure notices have been checked.
• Every connector, road crossing, and town segment has been reviewed.
• Private-property access is authorized.
• The group knows where the route begins and ends and has a turnaround plan.
• You have an offline map and a backup route reference.
• The machine is suitable for the terrain, weather, and trip length.

If one answer is uncertain, pause and resolve it before riding. A short call to the responsible agency can prevent a wasted drive, an avoidable citation, or a trip that puts the group on a route it cannot safely or legally use.

Colorado’s designated trails offer very different experiences, from wide public roads to narrow high-country routes. The dependable approach is to treat permits as necessary paperwork, not as proof that every trail is open. Verify the machine’s permit status, check the route with the land manager, and follow current signs and closures once you arrive.
