Dear Mr. Vandiver:

This responds to your letter in which you request information on Federal seat belt regulations. I apologize for the delay in our response. Your letter raises the issue of whether Federal law requires a person who is not a manufacturer, distributor, dealer or repair business and who installs temporary benches in the bed of a used pickup truck to equip each seating position with a seat belt. As discussed below, the answer is no.

By way of background information, the National Highway Traffic Safety Administration (NHTSA) is authorized to issue Federal motor vehicle safety standards applicable to the manufacture and sale of new motor vehicles and items of motor vehicle equipment. NHTSA has exercised this authority to establish Federal Motor Vehicle Safety Standard No. 208, Occupant Crash Protection (49 CFR 571.208), which specifies performance requirements for the protection of vehicle occupants in crashes. Standard No. 208 required model year 1988 pickup trucks to have a Type 2 (lap/shoulder) seat belt assembly at each forward-facing front outboard designated seating position, and either a Type 1 (lap) or Type 2 seat belt assembly at all other designated seating positions.

NHTSA's safety standards apply only to new motor vehicles and new motor vehicle equipment. Since the benches were installed in the pickup bed after the first purchase of the vehicle, Standard No. 208 does not apply directly to those benches. However, 49 U.S.C. 30122(b) applies in the case of used as well as new vehicles. That section reads as follows:

A manufacturer, distributor, dealer, or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable safety standard prescribed under this chapter unless the manufacturer, distributor, dealer, or repair business reasonably believes the vehicle or equipment will not be used (except for testing or a similar purpose during maintenance or repair) when the device or element is inoperative.

Section 30122(b) does not affect modifications made by vehicle owners to their own vehicles. Accordingly, looking at the specific factual situation identified by your letter, modifications made by a contractor who has been provided a vehicle for the contractor's sole use and operation are not subject to the provisions of this section .

As I am sure you are aware, however, individual States have the authority to regulate modifications that vehicle owners may make to their own vehicles and the operation of these vehicles. We offer no view on the impact of such State laws or whether they would apply to the operation of vehicles off of public roadways. Therefore, you should determine if any state laws govern this particular modification. In addition, while Federal law does not apply to a modification an individual makes to his or her own vehicle, NHTSA urges vehicle owners to exercise care when installing new seats, and to install seat belts for each seating position.

I hope you find this information useful. If you have any further questions, please feel free to contact Otto Matheke in NHTSA's Office of Chief Counsel at (202) 366-2992.

Sincerely,

John Womack
Acting Chief Counsel
