Is Wisconsin medium-speed vehicle friendly? No state law currently in place
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 license and registration required? For LSVs, yes. A Low-Speed Vehicle must be titled, registered, insured, and operated by a licensed driver in nearly every state. For boats, yes. A motorized vessel must be registered with the state’s marine or boating agency before it can be used on public waterways.
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.
Find out more information on federal standards for low-speed vehicles at the NHTSA Low-Speed Vehicle page.
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.
WisDOT handles LSV title and registration by mail using the MV14 application; local DMV service centers cannot process these applications in person. Its checklist includes ownership documents and a photo of the federal certification label. Use the current application and fee instructions for your transaction. WisDOT permits LSVs on local or county roads posted 35 mph or less. Connecting highways have a 25 mph limit unless the municipality allows up to 35 mph. Numbered-state-highway crossings require a limit of 35 mph or less and traffic signals. LSVs cannot travel on or cross controlled-access highways. Check the intended route and current local rules.

Register and title the boat with the Wisconsin DNR through the Go Wild portal (online) or by mailing Form 9400-193 (Boat Registration & Titling Application) with the MCO and proof of 5% use tax paid. The DNR issues a 3-year registration (expires March 31) and title ($5).
