TITLE: FMVSS INTERPRETATION

TEXT: This responds to Lucas Industries' November 1, 1977, request that the upcoming passive restraint requirements of Standard No. 208, Occupant Crash Protection, be amended to provide alternative compliance by means of installation of active lap and shoulder belts equipped with an ignition interlock system.

Section 125 of the National Traffic and Motor Vehicle Safety Act (the Act) provides in relevant part that "No Federal motor vehicle safety standard may . . . provide that a manufacturer is permitted to comply with such standard by means of . . . any safety belt interlock system." (15 U.S.C. 1410b(b)(1)). It is the agency's opinion that this provision operates as a strict prohibition on amendments of Standard No. 208 that would have the effect of permitting compliance by provision of an ignition interlock system. This opinion is confirmed by Conference Report language on @ 125 which states:

No matter what procedure is followed, the conference substitute prohibits the re-establishment of the safety belt interlock system or continuous buzzer as a mandatory or optional motor vehicle safety standard. H.R. Rep. 93-1452, 93rd Cong. 2d Sess at 45 (1974).

In view of this statutory prohibition, Lucas Industries' request for amendment of the upcoming requirements of Standard No. 208 cannot be considered by the agency.

SINCERELY,

Lucas Industries Inc

Subject Petition - Passenger Car Occupant Restraint

The Lucas Electrical Company Limited of Great Britain is, like ourselves, a subsidiary of Lucas Industries Limited.

Lucas Electrical, supported by us, feel that there should be an option to the passive restraint systems mandated in the early 1980's. We believe that, for some people, lap and shoulder belts with ignition interlock would provide a more acceptable alternative to the passive restraint systems presently being planned, and we ask that this option be considered.

A copy of the Lucas Electrical statement is attached.

Passive Restraint Systems - USA

Now that a regulation has been published requiring progressive introduction of passive restraint systems on new vehicles, it seems to us that the seat belt - ignition interlock system should be reconsidered.

This system had the blessing of NHTSA in terms of safety, who were unsuccessful in their attempts to prevent its withdrawal as a legal requirement in the USA. However, now that passive restraints can be anticipated the reasons for withdrawal of the interlock vanish, based as they were on avoiding the imposition of a requirement which was unpopular in some quarters. Should such a system be re-introduced, there would be no question of imposing it, and free choice could be exercised by any prospective buyer.

Thus, bearing in mind the undoubted safety potential of such a system, we propose that it be re-introduced based on the original technical requirements of NHTSA.
