NATM Debuts 2020 Guidelines for Trailer Manufacturing

NATM News,

The National Association of Trailer Manufacturers (NATM), known as the resource for safety and compliance for the light- and medium-duty trailer industry, has published the 2020 edition of the Guidelines. This massive document takes the guesswork out of meeting federal requirements governing the manufacturing of trailers under 26,000 lbs. GVWR and is a benefit of NATM membership.

Building trailers to meet the federal regulations outlined in the NATM Guidelines is not optional. It is required by law and enforced by law enforcement every day on the nation’s roadways. But it can be very time-intensive for trailer manufacturers to research the numerous federal rules, regulations, standards, and accepted industry practices that govern trailer construction.

NATM addresses this by compiling the Guidelines for Recommended Manufacturing Practices for Light- and Medium-Duty Trailers. The document consists of over 400 pages of laws, regulations, rules, standards, and industry best practices. This information is gathered from resources such as the U.S. Department of Transportation, the Society of Automotive Engineers, Inc., the American Association of Motor Vehicle Administrators, the Recreational Vehicle Industry Association, the Traffic Safety Administration, the Maintenance Council, and the National Electrical Manufacturers Association amongst others. The Guidelines is updated annually by industry experts that stay abreast of changing regulations and who vet the addition of recommendations and best practices.

Members report substantial time savings by utilizing the Guidelines, particularly on the topics of lighting and reflectors, VIN and data plates, gross vehicle weight ratings, and state brake requirements. While the Guidelines focus on U.S. regulations, many may have an interest in Canadian compliance. For more information, visit Transport Canada’s website at

In recent years, the National Highway Traffic Safety Administration (NHTSA) has increased its enforcement activity concerning the compliance of motor vehicle manufacturers, including trailer manufacturers. NHTSA has placed particular concern on meeting tire recordkeeping requirements, which includes both manufacturer records as well as the provision of TIN cards to dealers, distributors, and purchasers. This is only one of the many requirements outlined in NATM’s Guidelines.

NATM assists its trailer manufacturing members in avoiding costly fines and decreasing liability related to trailer compliance through the NATM Compliance Verification Program (CVP). The NATM CVP is an unbiased, third-party audit of the trailer manufacturing process and uses the Guidelines as the backbone for the program. The CVP provides biennial on-site consultations to trailer manufacturers and technical assistance throughout the entire process to ensure companies are manufacturing trailers consistent with Federal Motor Vehicle Safety Standards and other industry best practices.

Once a trailer manufacturer has successfully passed the Compliance Verification Program, the company is able to purchase NATM Decals and market their company’s dedication to fulfilling their safety requirements by participating in an unbiased, third-party audit of their trailers. While participation in the NATM Compliance Verification Program is an additional, voluntary cost for manufacturers, there are economic benefits of participation.

“The first-year sales saw a 20 percent boost and blew past the forecast over three years for the sales improvements for revenue targets for the existing trailer product. We will continue to use up the [NATM] labels we have in stock, and then order more,” said Pete Dixon, Engineer at Karcher North America, Inc., regarding the benefit of being a member of the National Association of Trailer Manufacturers.
