Tracked ATVs in Colorado: What the State Publishes

Colorado's OHV definition at C.R.S. 33-14.5-101(3) names tracks directly, alongside wheels, as a qualifying means of travel. On our reading that means a rubber-track conversion does not push the machine out of the OHV chapter on account of the tracks. The definition then carves out a list of things that are not OHVs, and the second carve-out is snowmobiles. Colorado defines a snowmobile at C.R.S. 33-14-101(11) as "a self-propelled vehicle primarily designed or altered for travel on snow or ice when supported in part by skis, belts, or cleats." The words "or altered" and "belts, or cleats" are why a tracked quad can arguably land in either category: it is an altered vehicle supported by belts or cleats. The hinge is the word "primarily." A machine on tracks year round for mud, swamp and soft ground does not read as primarily a snow machine; a machine tracked up for the winter is a closer call. Colorado Parks and Wildlife registers both OHVs and snowmobiles and is the office to settle which registration applies.

(3) "Off-highway vehicle" means any self-propelled vehicle that is designed to travel on wheels or tracks in contact with the ground, designed primarily for use off of the public highways, and generally and commonly used to transport persons for recreational purposes. Except as described in subsection (3)(h) of this section, "off-highway vehicle" includes surplus military vehicles as defined in section 42-6-102. "Off-highway vehicle" does not include the following: (a) Vehicles designed and used primarily for travel on, over, or in the water; (b) Snowmobiles;C.R.S. 33-14.5-101(3) (definition and the first two exclusions), Colorado Revised Statutes 2026, Title 33 (Office of Legislative Legal Services) — source · read 2026-09-26

Every OHV operated in Colorado, or merely possessed at a staging area, must be registered and numbered under Article 14.5 unless one of the exemptions applies. Colorado residents get a registration card and two decals; per CPW the cost is $26.25 and both registrations and permits run April 1 through March 31 and are required annually. Non-residents are covered by a narrow statutory allowance rather than a flat bar: C.R.S. 33-14.5-102(6)(b) and (9)(a) let a machine owned by a resident of another state or country operate in Colorado without Colorado registration if it is covered by a valid licence or registration of that state or country AND has not been within Colorado for more than thirty consecutive days; past that, the division issues a nonresident OHV permit, and CPW also requires an OHV Permit for any plated, street-legal vehicle used on designated OHV trails. Other statutory exemptions at 33-14.5-102(6) include government-owned machines, machines used strictly for agricultural purposes, machines used strictly on private property, machines in authorized organized events, and dealer or manufacturer machines used for operator education. If the machine is instead classified as a snowmobile, registration runs under C.R.S. 33-14-102 with CPW, valid October 1 through September 30.

Except as provided in subsection (6) of this section, and except as provided for nonresident-owned and -operated off-highway vehicles in subsection (9) of this section, no person shall operate, nor have in his or her possession at any staging area, any off-highway vehicle within the state unless such off-highway vehicle has been registered and numbered in accordance with the provisions of this article.C.R.S. 33-14.5-102(1)(a) — source · read 2026-09-26

Registering a Tracked Quad sets several named agencies' own class definitions side by side, and shows that they are not written to a common test. It settles nothing for Colorado; what Colorado publishes is directly above.

A registered OHV - tracks included, on the face of the statutory definition - may be ridden on Colorado's designated OHV routes, staging areas, public land roads and designated trails. That is a large network: CPW points riders at the Colorado Trail Explorer (COTREX), which it says covers nearly 45,000 miles of trails, and says OHV user fees of over $4 million annually fund trail maintenance, trailheads and signage. The condition is designation: you must be on a route open to your vehicle type, marked with brown signs with white graphics on state land and identified on Forest Service motor vehicle use maps on national forest. We found no statewide vehicle width limit in Colorado law, so trail-by-trail width and vehicle-class designations set by the federal or local land manager are what actually govern.

All Off-Highway Vehicles must have either a current or valid Colorado Registration Card and two Decals or one Colorado Off-Highway Vehicle Permit to operate in Colorado.Colorado Parks and Wildlife, "Register an Off-Highway Vehicle" — source · read 2026-09-26

OHV use on Colorado's public streets, roads and highways is prohibited by default, but the statute then lists nine situations in which it is allowed - and several of them are the ones riders actually use. A street, road or highway designated open by the state or a state agency is open. Crossings of streets, roads, highways and railroad tracks are permitted under 33-14.5-108.5, as is traversing a bridge or culvert. Local governments may by ordinance or resolution establish OHV routes on city streets and county roads, though never on a state highway system road. Agricultural use, declared emergencies and lawfully conducted special OHV events are also excepted. A violation is a civil infraction with a fifty dollar fine. If the machine is registered as a snowmobile instead, C.R.S. 33-14-110(3)(e) separately allows operation on streets and highways "which are not maintained for winter motor vehicle traffic" - a useful winter permission for a tracked machine if it is in the snowmobile class.

It is unlawful to operate an off-highway vehicle on the public streets, roads, or highways of this state, regardless of the state or other jurisdiction in which the off-highway vehicle is registered or titled, except in the following cases: (a) When a street, road, or highway is designated open by the state or any agency of the state; (b) When crossing streets or when crossing roads, highways, or railroad tracks in accordance with section 33-14.5-108.5; (c) When traversing a bridge or culvert;C.R.S. 33-14.5-108(1) — source · read 2026-09-26

Roads, Shoulders and Crossings separates crossing a road from travelling along one in several named jurisdictions, because most of them do. It settles nothing for Colorado; what Colorado publishes is directly above.

On federal public land in Colorado - and much of the state's riding is on national forest and BLM - state law itself makes the federal travel plan enforceable: it is unlawful to operate a motor vehicle on any federal public land, trail or road unless that land, trail or road is signed or otherwise authorized for such use. The same provision opens with an exception for paragraph (d) of that subsection, and it bars a peace officer from enforcing the rule inside a federal unit until the land manager has actually identified available routes by map, route marker or sign. Separately, C.R.S. 33-14.5-112 requires an off-highway use permit on a highway-registered vehicle from another state that is being used for recreational travel on designated OHV routes. We found no statewide statutory width limit on OHVs in Colorado; width and vehicle-class limits come from the individual land manager's designation.

Except as otherwise provided in paragraph (d) of this subsection (3), it is unlawful for a person to operate a motor vehicle on any federal public land, trail, or road unless the federal public land, trail, or road is signed or otherwise authorized for such use. A peace officer shall not enforce this paragraph (a) within an administrative unit of federal public land until the controlling land management agency identifies whether a route is available for motorized travel by maps, route markers, or signs that are available to the public and provide information to determine whether the route is authorized.C.R.S. 33-14.5-108(3)(a) — source · read 2026-09-26
