National Highway Traffic Safety Administration January 26, 2018 – Federal Register Recent Federal Regulation Documents

This document denies a petition for rulemaking submitted by Mr. William H. Thompson III requesting NHTSA amend Federal Motor Vehicle Safety Standard (FMVSS) No. 108, Lamps, reflective devices, and associated equipment. Specifically, Mr. Thompson requested we revise the activation process for red and amber signal warning lamps on school buses to require a new intermediate step during which both colors are activated simultaneously and flash in an alternating pattern and that we decouple the process by which lamps transition to the red-only configuration from the opening of the bus entrance door. NHTSA is denying this petition because Mr. Thompson has not identified a safety need to justify making changes he requested, and Mr. Thompson did not provide persuasive quantitative data to show adopting his requested changes would result in a net benefit to safety.
