TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your letter of July 31, 1973, concerning the effect of our Standard 208 on State laws requiring vehicles to be equipped with seat belts.

Section 103(d) of the National Traffic and Motor Vehicle Safety Act, 15 U.S.C. 1392(d), reads:

Whenever a Federal motor vehicle safety standard established under this title is in effect, no State or political subdivision of a State shall have any authority either to establish, or to continue in effect, with respect to any motor vehicle or item of motor vehicle equipment any safety standard applicable to the same aspect of performance of such vehicle or item of equipment which is not identical to the Federal standard. . . .

Standard 208 (49 CFR 571.208) permits passenger cars to be manufactured under any one of several options for occupant crash protection. One of these options is "complete passive protection", under which the vehicle must undergo a series of rigorous crash tests, in which instrumented dummies without belt restraints show force levels that would not create serious injury to a human occupant in most cases. Manufacturers are not required by the standard to have seat belts at any position that meets the requirements of this option.

The NHTSA considers that Section 103(d), quoted above, clearly renders void any State laws or regulations to the extent that they would require a vehicle to be equipped with seat belts at seating positions that comply with the complete passive protection option. Any State requirements that are not "identical" to these of an applicable standard are preempted by that section, under basic Constitutional principles of the supremacy of Federal law.

I am enclosing some information on the efficacy of air cushion restraints, as you requested. We are pleased to be of assistance.

Sincerely,

Enclosure

ATTACH.

OFFICE OF THE ATTORNEY GENERAL

July 31, 1973

Lawrence R. Schneider, Esquire -- Chief Counsel, NHTSA

Dear Mr. Schneider: This is in reference to a recent telephone conversation with Mr. Dick Dyson in respect to the projected program of General Motors Corporation to market one hundred thousand automobiles equipped with "air bags" instead of safety belts.

As you know, a number of states have statutes requiring that all passenger cars or other motor vehicles registered after certain dates shall be equipped with safety belts. Chapter 357, Acts of Assembly of 1962, embodied in @ 46.1-309.1, Code of Virginia (1950), as amended, requires all motor vehicles registered in this State designed and licensed primarily for private passenger vehicular transportation on the public highways, and manufactured for the year 1963 or subsequent years, to be equipped with safety lap belts or a combination of lap belts and shoulder straps or harnesses. In 1968 an amendment was added which requires that "Passenger motor vehicles registered in this State and manufactured after January 1, 1968, shall be equipped with lap belts or a combination of lap belts and shoulder straps or harnesses as required to be installed at the time of manufacture by the Federal Department of Transportation."

In view of the last quoted amendment, it seems clear that the safety belt requirements for such vehicles in this State are dependent upon the requirements of the Federal Department of Transportation. Further, I am aware of the premise of over-riding power in the case of conflict between State and Federal law. For the benefit of this and other states in further clarifying this situation, however, it is requested that you render an opinion on the question of validity of State laws requiring that vehicles be equipped with safety belts. In this, your attention is directed to Public Law 89-563, 89th Congress, S. 3005, September 9, 1966, and Motor Vehicle Safety Standard No. 208. Any additional information on the efficacy of "air bags" as opposed to safety belts would be most helpful.

Respectfully yours,

A. R. Woodroof -- Assistant Attorney General
