| 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 to inform the public of such compliance when purchasing equipment.
The NMMA program certifies that the design meets the standards in the NMMA
Trailer Certification Handbook. The manufacturer has the responsibility
of assuring that their production units are manufactured in compliance with
the certified design.
Both the administrative and technical details of this program is incorporated
in the handbook. The trailer certification standards used are based on
those published by the Society of Automotive Engineers (SAE) and in the
Code of Federal Regulations (CFR) Title 49.
Trailers are certified in the areas of identification plates, capacity
ratings, couplings, safety chains, lighting, winches, brakes, registration
procedures, and conspicuity systems.
A manufacturer participating in this program must certify all models
as fitted with all factory supplied equipment on a model year basis.
Inspectors from nationally recognized independent inspection agencies
or NMMA staff visit the manufacturer and physically inspect each trailer
model for compliance to all certification standards.
Trailer manufacturers desiring to participate in this program should
contact NMMA Engineering Standards Department.
