Off-Road Use: Registration Requirements

In Colorado, dirt bikes used exclusively off-road are not required to be titled but must be registered with Colorado Parks and Wildlife (CPW). This applies to both residents and non-residents operating on public lands or designated OHV trails.

Registration Details:

  • Colorado OHV Permit: Required for all off-highway vehicles (OHVs) operated on public lands or trails.

  • Out-of-State OHVs: Must also display a current Colorado OHV permit when operating on designated OHV trails or routes.

Helmet and Eye Protection:

  • Under 18: Operators and passengers under 18 are required to wear a DOT-approved helmet.

  • All Riders: Eye protection is mandatory for all riders, regardless of age.

Age Restrictions:

  • Under 10: Prohibited from operating OHVs on public roads.

  • Ages 10–15: May operate OHVs on public roads only under the direct supervision of a person with a valid driver’s license.

Operation on Public Roads:

  • Off-road vehicles, including dirt bikes, are generally prohibited from operating on public roads unless they have been modified to meet street-legal requirements and are registered accordingly. However, many counties and municipalities in Colorado have opened certain roads within their jurisdiction to OHV use.

Lighting Requirements:

  • When operating during low-light conditions, the dirt bike must be equipped with a functioning headlamp and taillamp.
