TITLE: FMVSS INTERPRETATION

TEXT: This will acknowledge receipt of the petition by Motor Coach Industries, dated July 22, 1977, for a determination that an apparent noncompliance with Motor Vehicle Safety Standard No. 121 is inconsequential as it relates to motor vehicle safety.

We are preparing a notice for publication in the Federal Register requesting public comment on your petition and you will be notified in due course as to its disposition. The notice will not include reference to the fact that the "continuous warning" signal required by S5.1.5 of Standard No. 121 is an automatic flashing light on MCI vehicles. It is the opinion of this office that either an automatic flashing light or a continuous light will provide a "continuous warning" within the intent of the Standard.
