The National Marine Manufacturers Association has developed a trailer certification program to help boat trailer manufacturers comply with established industry standards and federal safety regulations, and to help inform the public of such compliance when purchasing trailers. Trailers are certified in the areas of identification plates, capacity ratings, couplings, safety chains, lighting, winches, brakes, registration procedures, and conspicuity systems.
Inspectors visit the manufacturer and physically inspect each boat trailer model for compliance to all certification standards.
A manufacturer participating in this program must certify all models as fitted with all factory supplied equipment on a model year basis.
