ATTACHMT: Attached To 1/6/94 Letter From C. N. Littler To Mary Versailles

TEXT: This responds to your letter concerning whether a New York State law addressing the in-use stopping ability of privately owned motor coaches is preempted by Federal law. I apologize for the delay in our response. The New York law states that a vehicle must be capable of stopping "at a rate of deceleration equivalent to a stop within 22.2 feet from a speed of 20 miles per hour." You believe that @103 (d) of the National Traffic and Motor Vehicle Safety Act ("Safety Act") preempts the New York law, sinc e the state law is not identical to Federal motor vehicle safety standard No. 121, Air Brake Systems. Please note that the Safety Act has been codified at 49 U.S.C. 30101 et seq. and that the citation for 103(d) is now 49 U.S.C. @ 30103.

As explained below, Standard No. 121 currently does not have stopping distance requirements in effect; therefore, the New York law is not currently preempted by a Federal safety standard. Nevertheless, the agency has issued a proposal to reinstate stopp ing distance requirements in Standard No. 121. (58 FR 11003, February 23, 1993). If the agency issues a final rule to reinstate stopping distances, then any more stringent requirements in the New York law (addressing the same aspects of performance as Standard No. 121) would be preempted.

Title 49 U.S.C. @ 30103 states:

Whenever a Federal motor vehicle safety standard . . . 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 equipm ent 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.

I hope this information is helpful. If you have any questions about NHTSA's safety standards, please feel free to contact Marvin Shaw at this address or by telephone at (202) 366-2992.
