DATE: March 17, 1994

FROM: Eric T. Stewart -- Engineering Manager, Mid Bus

TO: Office of Chief Counsel, NHTSA

TITLE: Reference: Amendment to FMVSS 571.217 published in the Federal Register November 11, 1992 (Docket 88-21 notice No. 3)

ATTACHMT: Attached to letter dated 4/1/94 from John Womack to Eric T. Stewart (A42; Std. 217); Also attached to letter dated 7/7/93 from John Womack to Thomas D. Turner

TEXT:

The background to this amendment indicates that the "final rule requires a minimum of 1 inch wide retro-reflective tape ...." (page 49421). The actual amendment reads that the retro-reflective tape is to be "a minimum 3 centimeters wide". (page 49425) (CFR571.217 S 5.53(c)). These two dimensions are not the same since 1.00 inch is equal to 2.54 centimeters.

I believe that the intent of this rule making was to make the retro-reflective tape 1.00 inch wide and an error has taken place in converting the dimension to metric units. I am requesting written clarification indicating how wide NHTSA wants the retro-reflective tape around the outside perimeter of a school bus emergency door.

If you have any questions, please call me at (419) 221-2525.
