Colorado ATV laws require every off-highway vehicle to be registered with Colorado Parks and Wildlife before it touches public land, set minimum equipment standards, restrict riding to designated routes, and hand counties broad authority to add their own rules on top. Annual registration is $26.25, and the state uses “off-highway vehicle” (OHV) as an umbrella term that covers ATVs, dirt bikes, side-by-sides, and UTVs.
Registration and Permits
Any OHV on public land, a designated trail, or even a staging area has to carry a current Colorado registration or a Colorado OHV permit. Registration runs April 1 through March 31 and costs $26.25, which includes a $1.25 search-and-rescue surcharge. First-time registrants submit proof of ownership with the application and receive two decals and a registration card. On a four-wheel ATV, the decals go in a visible spot on each side of the front fenders.1Colorado Parks and Wildlife. Register an Off-Highway Vehicle
Out-of-state riders skip registration but must buy a non-resident OHV permit before riding.2colorado.gov.

Already have a street-legal plated vehicle like a Jeep or truck that you want to run on OHV trails? You still need a separate Colorado OHV permit for it.
Equipment Your ATV Must Have
Colorado sets minimum mechanical standards for every OHV on public land, and CPW rangers routinely check compliance on trail patrols.
- A braking system operable by hand or foot that meets the state’s deceleration standard.3Colorado Secretary of State. 2 CCR 405-5 – Chapter P-5 Off-Highway Vehicle Regulations
- A properly maintained muffler. Noise output must stay within the limits set by C.R.S. 25-12-110, so an aftermarket exhaust that pushes past the legal ceiling can draw a citation.3Colorado Secretary of State. 2 CCR 405-5 – Chapter P-5 Off-Highway Vehicle Regulations
- A U.S. Forest Service-approved spark arrestor, installed and working, with a permanent “qualified” or “approved” stamp. Given the wildfire risk, enforcement takes this one seriously.3Colorado Secretary of State. 2 CCR 405-5 – Chapter P-5 Off-Highway Vehicle Regulations

Where You Can Legally Ride
On federal land, motorized travel is limited to routes specifically designated for OHV use. The U.S. Forest Service publishes Motor Vehicle Use Maps (MVUMs) for each national forest, and those maps are the legal authority on which trails are open, what vehicle types are allowed, and when seasonal closures apply. Riding off a designated route or entering a wilderness area with a motorized vehicle is a federal violation. The Bureau of Land Management similarly designates routes and areas on its land as open, limited, or closed.
On state land, CPW manages access through designated trail systems. State wildlife areas and state trust lands have their own access rules and are generally not open to recreational OHV riding.
Riding on County Roads
Colorado law generally prohibits operating an OHV on public streets, roads, and highways. The same statute carves out exceptions: counties and municipalities can pass ordinances opening specific city streets or county roads to OHV traffic, though no road on the state highway system can be designated as an OHV route.4Justia. Colorado Code 33-14.5-108 – Off-Highway Vehicle Operation Prohibited on Streets, Roads, and Highways You can also cross a paved road or highway at a right angle to connect trails, and traverse bridges and culverts.
Each county writes its own rules for riding on its roads. Some require a valid driver’s license and liability insurance. Others add helmet mandates for riders under 18, eye protection, speed limits, and lighting requirements. Requirements can differ sharply between neighboring counties, so check the specific county ordinance before you ride.
Age and License Rules
Colorado does not require a driver’s license to operate an OHV on designated backcountry trails. The state sets age-based rules instead. Riders 10 through 15 can ride on public land under the direct supervision of a licensed driver. Riders 16 and older can operate independently. Children under 10 are not permitted to operate an OHV on public land.
Those minimums are the floor. Once you move onto a county road opened by local ordinance, the rules tighten. Many counties require every operator to hold a valid driver’s license regardless of age, which effectively pushes the minimum to 16 there. Parents are legally responsible for what minors do behind the handlebars and can face citations if a child is riding without proper supervision.
Local Rules That Layer on Top
Colorado gives counties and municipalities broad authority to add safety mandates beyond state law. A local ordinance can require any of the following for OHV operation within its jurisdiction:5Colorado General Assembly. Off-Highway Vehicles
- A driver’s license for all operators.
- Liability insurance. There is no statewide OHV insurance mandate, but individual counties do impose one.
- Helmets for riders 18 and younger.
- Eye protection such as goggles, sunglasses, or prescription glasses.
- Seatbelts and child restraints in side-by-sides and UTVs equipped with them.
- Occupant limits.
A rider crossing several counties on one trip can hit different rules along the way. Checking ahead saves a citation you didn’t see coming.
DUI and Right-of-Way
Colorado’s DUI statute applies to all vehicles, not just cars and trucks. Operating an OHV while under the influence carries the same consequences as a DUI on a highway, including arrest, fines, and potential loss of your standard driving privileges.6Justia. Colorado Code 42-4-1301 – Driving Under the Influence – Driving While Impaired – Driving With Excessive Alcoholic Content – Definitions – Penalties The statute separates “driving under the influence” from the lesser “driving while ability impaired,” but both are criminal offenses. A remote trail is not outside the reach of enforcement; CPW rangers and county sheriffs patrol OHV areas and conduct sobriety checks.
Right-of-way rules also carry legal weight. OHV riders must yield to non-motorized users, including hikers and people on horseback. When you meet horses on the trail, shut off your engine and let them pass.
Accident Reporting
An OHV accident that causes at least $1,500 in property damage, an injury requiring hospitalization, or a death must be reported within 48 hours.7Colorado Parks and Wildlife. Off-Highway Vehicle and Snowmobile Registrations and Permits The report goes to a law enforcement agency (Colorado State Patrol, the county sheriff, or the local police department where the accident happened) and to CPW. CPW asks you to complete its OHV/Snowmobile Accident Reporting Form and send it to the OHV/Snowmobile Program Manager.
Failing to report a qualifying accident is a class 2 petty offense with a $75 fine.7Colorado Parks and Wildlife. Off-Highway Vehicle and Snowmobile Registrations and Permits The fine is small, but a missed report can complicate things later if injuries worsen or a liability dispute develops. When you’re unsure whether damage clears the $1,500 threshold, report it.
