TEXT:

This responds to your letter of December 1, 1993, in which you asked whether two trailers on which are mounted specialized equipment would be classified as motor vehicles. We are sorry we were unable to respond by your requested date of December 14, 1993.

You stated that the trailers in question were manufactured in Greenville, TN in 1991 and Shipped to a company in Canada which is no longer in business. A transportable soil remediation plant was mounted on the trailers, but they have not been used or moved since their delivery. You stated that you now expect to import the trailers with their mounted equipment into the U.S. for use as a transportable soil remediation plant. You stated that the trailers will not be registered and will be moved only with permits because the anticipated projects for the equipment are long term and "the trailers will hardly see the road in their lifetime." You stated that the trailers will be inspected before they are moved to assure their safety, and that you will assure the safety of the equipment on the road while transporting it from Vancouver, Canada to your shop in San Diego, CA. You enclosed with your letter a certificate of origin, pictures of the trailers with the equipment mounted thereon, a letter from the company that originally purchased the trailers, and a letter from the manufacturer of the trailers.

By way of background information, the National Traffic and Motor Vehicle Safety Act of 1966, 15 U.S. Code S1381 to S1431, as amended (Safety Act), authorizes the National Highway Traffic Safety Administration (NHTSA) to issue Federal Motor Vehicle Safety Standards applicable to new motor vehicles or new items of motor vehicle equipment manufactured or imported for sale in the U.S. The term "motor vehicle" is defined in the Safety Act as:

(A)ny vehicle driven or drawn by mechanical power manufactured primarily for use on the public streets, roads, and highways, except any vehicle operated exclusively on a rail or rails.

NHTSA has interpreted that language as follows. Vehicles that are equipped with tracks or that are otherwise incapable of highway travel are clearly not motor vehicles. In addition, vehicles designed and sold solely for off-road use, such as airport runway vehicles and underground mining devices, are not considered motor vehicles, even though they may be operationally capable of highway travel. Vehicles that have an abnormal body configuration that readily distinguishes them from other highway vehicles and that have a maximum speed of 20 miles per hour are not considered motor vehicles, nor is equipment that uses the highways solely to move between job sites and which typically spends

extended periods of time at a single job site. Those vehicles or equipment are not considered motor vehicles because their intended use of the public roads is intermittent and incidental to their primary off-road use.

Based on your representations that your trailers will be utilized on long-term off-road projects, they would not be classified as motor vehicles. Therefore, they would not be subject to the U.S. Federal motor vehicle safety standards nor the import requirements of 49 CFR 591.5. That determination, however, does not mean that the trailers would necessarily be exempt from state motor vehicle requirements, especially the states through which you intend to transport the equipment from Vancouver to San Diego. For information on state laws in that regard, you may contact the American Association of Motor Vehicle Administrators, 4200 Wilson Boulevard, Suite 600, Arlington, VA 22204, (703) 522-4200.

I hope this information is helpful to you. Should you have any further questions or need additional information, please feel free to contact Walter Myers of my staff at this address or at (202) 366-2992.
