Other Vehicle Registrations in Colorado

Summary: How to Register Special Vehicle Types in Colorado

For vehicle types other than standard cars and trucks, the registration process can be a little different—including requirements for ATVs, trailers, and boats. Other vehicles are easier, as they utilize standard registration processes; these include recreational vehicles and custom-built cars, though custom vehicles must first apply for a VIN.

This page gives you all the information you need to register your special vehicle and avoid being hit with a fine and other penalties.

ATVs and Snowmobiles in Colorado

Yes, you do have to register your ATV or snowmobile before you head to the back country to enjoy Colorado's great outdoors. In fact, all off-highway vehicles (OHVs) need registration, including dirt bikes, three-wheelers, and dune buggies.

The registration process is a little different to registering your car. Instead of registering through the Colorado Division of Motor Vehicles (DMV), you register through the Parks and Wildlife Registration Unit using a Registration Application (Form APRG09001). Once you've completed the form, you can return it to:

Parks and Wildlife Registration Unit
13787 South Highway 85
Littleton, CO 80125

You may also go to a State Park office or OHV agent. Visit the appropriate website for a complete list of OHV agents or snowmobile agents.

Registration Fees

OHV registration currently costs $25.25 and is valid until March 31st. Snowmobile registration currently costs $30.25 and is valid from October 1 to September 30. Partial year registrations cannot be prorated.

Registration Renewal

The easiest way to renew your registration is online. All you need is the vehicle registration, payment for the appropriate fees, and to print out a temporary permit.

If you're more comfortable without a computer, you can always complete the registration renewal card and send it to the indicated address.

Custom-Built Car Registration

To register your custom-built car in Colorado, you will first need to apply for a vehicle identification number (VIN). First have it inspected by a member of law enforcement. If it passes the inspection, you will be given a Colorado Certified VIN Inspection form (Form DR 2704).

Next, visit your local Colorado DMV office with:

Once you have your VIN, take the Colorado Certified VIN Inspection form (Form DR 2704) to an emissions testing center. It must pass the emissions test before you can register it.

Once this is done, you're ready to have it registered, which is the same process as registration a standard car or truck. Visit our Colorado Car Registration page for steps.

Trailer Registration in Colorado

Colorado does require you to register your trailer. To do this, you need a valid title on it. Some states don't title trailers, so if this is the case you'll want to go to your local county office with documentation that you own the vehicle. A bill of sale works best, but you can always use a Statement of Trailer Ownership (Form DR 2374).

You'll also want to have the following:

  • Vehicle identification number (VIN) verification, if you're coming from out of state.
  • Colorado driver's license.
  • Proof of insurance for the vehicle pulling the trailer.

If you were handy enough to build or assemble your own trailer, it still needs titling. To get your title and registration, you'll use the same procedure as a regular trailer, but you'll also have to complete a Statement of Assembly of Homemade Trailer and Assignment of Trailer I.D. Number (Form DR 2409). In addition, you'll have to provide a bill of sale for all materials used to put the trailer together, such as axles and wheels.

Boats and Small Vessels

There are quite a few people out there who say boats and trailers go hand in hand. Once you've titled and registered your trailer, you'll have to register your boat, too. See our boat registration page for more information.

RVs and Campers in Colorado

Recreational vehicles, motorhomes, and campers all use the same registration processes as standard vehicles in Colorado. You will simply need to be prepared to pay a different fee, based upon the size and empty weight of your RV. Visit our page on Colorado Car Registration for the steps to register your motorhome or RV.

Motorcycles and Mopeds
