ATVs must be registered with Colorado Parks and Wildlife. Colorado residents will need to register ATVs, while non-residents simply need a permit. The OHV registration is $25.25 for one year. For Colorado residents registering their ATV for the first time, fill out and send the OHV Registration Form and a proof of ownership of the ATV to the Colorado Parks and Wildlife Registration Unit. However ATVs can also be registered at OHV dealerships and various Colorado Parks and Wildlife office locations. For Colorado residents needing to renew registration, online renewal is available.
