This is an in-depth guide to Colorado Low-Speed Vehicle (LSV) and Boat Registration Laws. We created this guide to help you understand Colorado’s registration requirements for vehicles that operate on both land and water.
Street-legal registration and operating rules for low-speed vehicles vary by state and local jurisdiction and may change. This information is general guidance only. Confirm current requirements with your state DMV and local authorities before registering or operating your WaterCar on public roads.
Is Colorado medium-speed vehicle friendly? No state law currently in place.
Under current NHTSA regulations, a Low-Speed Vehicle (LSV) is a four-wheeled motor vehicle with an attainable speed of more than 20 miles per hour but not more than 25 miles per hour on a paved level surface, and a gross vehicle weight rating of less than 3,000 pounds.
The federal standard (FMVSS No. 500, 49 CFR 571.500) requires low-speed vehicles to be equipped with headlamps, stop lamps, turn signal lamps, taillamps, reflex reflectors, parking brakes, rearview mirrors, windshields, seat belts, and a 17-digit vehicle identification number (VIN).
An LSV is NOT a golf cart. A golf cart is generally designed for speeds of 20 mph or less, is not federally regulated as a street vehicle, and in most states cannot be titled or registered for on-road use. Manufacturers self-certify compliance with the applicable federal safety standards. Registration and road access are separate questions for state and local authorities.

USCG guidance distinguishes state registration from federal documentation. Registration and display requirements depend on the vessel and the state of principal use. Check the state boating authority’s current requirements.
The Hull Identification Number (HIN) identifies the vessel and is separate from the road vehicle’s VIN. Use the hull identification and manufacturer’s ownership records when preparing the vessel application. The issuing agency determines how the HIN is verified.
Boat registration is handled by different agencies depending on the state – it may be the DMV, a Department of Natural Resources, a Fish & Wildlife agency, or a Parks & Wildlife department. Registration terms and renewal schedules vary; use the responsible agency’s current schedule.
Colorado DMV describes low-speed electric vehicles as approved for limited on-road use. Most are titled and registered as Tax Class C vehicles with passenger plates through the county motor vehicle office. Registration does not settle permission to use a specific route; check the state and local operating rules for the roads and crossings you plan to use.

Register the boat with Colorado Parks & Wildlife. Provide the HIN and proof of ownership and pay the fee; CPW issues the registration and numbers.
