What You Need to Know About Trailer Registration
Every state requires trailers that are towed on public roads to be registered through the state motor vehicle agency, typically the DMV. This covers a wide range of trailers: boat trailers, utility trailers, cargo trailers, car haulers, enclosed trailers, and more. Travel trailers (RVs) and fifth wheels are also required to be registered but may have separate fee schedules.
Trailer registration fees are typically based on the trailer's gross weight rating (GVWR) or actual weight. Light utility trailers and small boat trailers typically register for $15 to $35, while heavier trailers may cost $50 to $100 or more. Most states offer multi-year or permanent registrations for trailers, which can save time and reduce the hassle of annual renewals.
In addition to registration, trailers must have proper lighting (brake lights, turn signals, running lights), reflectors, and license plate illumination. Trailers over a certain weight may be required to have brakes, safety chains, and in some states, a separate brake controller inspection. Operating an unregistered trailer on public roads can result in fines similar to those for unregistered motor vehicles.
Some states offer permanent trailer registration for trailers that do not change ownership often - paying a higher one-time fee in lieu of annual renewals. This can be a cost-effective option for boat trailers, utility trailers, and other trailers you plan to keep long-term.
