RE: A. Lameier 513-684-3915

Dear Mr. Lameier:

This is in response to your letter requesting clarification concerning the classification of a Davey mobile compressor. You state that the manufacturer of the compressor indicates that the wheeled compressor need not comply with Standard No. 108, Lamps, reflective devices and related equipment, because the compressor is not a trailer. Based on the information provided with your letter, we believe that the compressor is not a motor vehicle and is therefore not subject to the requirements of Standard No. 108 or any other Federal motor vehicle safety standards.

By way of background, our agency is authorized, under the National Traffic and Motor Vehicle Safety Act of 1966 (Safety Act; 15 U.S.C. 1381 et seq.) to issue safety standards applicable to new motor vehicles and items of motor vehicle equipment. The National Highway Traffic Safety Administration (NHTSA) does not approve motor vehicles or motor vehicle equipment. Instead, the Safety Act establishes a "self-certification" process under which each manufacturer is responsible for certifying that its products meet all applicable safety standards.

A "trailer" is defined at 49 CFR /571.3 as "a motor vehicle with or without motive power, designed for carrying persons or property and for being drawn by another motor vehicle." The mobile compressor shown in the brochure enclosed with your letter appears to be designed for carrying property (the compressor) and for being drawn by a motor vehicle. The answer to your question of whether this compressor is a trailer, then depends on whether the compressor is a "motor vehicle" within the meaning of the Safety Act. Section 102(3) of the Safety Act (15 U.S.C. 1391(3)) defines a "motor vehicle" as

any 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.

We have interpreted this language as follows. Vehicles such as forklifts and mobile construction equipment which are sold primarily for off-road use, but which incidentally use the public roads to travel from one job site to another, are not considered motor vehicles. On the other hand, vehicles which regularly use the public roads and stay off-road for only limited periods of time are motor vehicles and are subject to our safety standards.

The agency has previously concluded in a July 1, 1980 letter to Mr. E.C. Elliott (copy enclosed) that his company's portable air compressors were not motor vehicles, based on statements that these devices spend the bulk of their useful lives on construction sites and are seldom drawn over public roads by mechanical power. If the Davey portable compressors are used in the same fashion as the compressors discussed in the July 1, 1980 letter, we believe that the Davey compressors were properly classified by the manufacturer as something other than a "motor vehicle". This means that the Davey compressors are not subject to any of the Federal motor vehicle safety standards.

I hope this information has been useful. My apologies for the delay in responding to your letter.

Sincerely,

Erika Z. Jones Chief Counsel
