Parts and Accessories Necessary for Safe Operation; Application for an Exemption From Grote Industries, LLC

This notice advises the public of new information that FMCSA believes is relevant to the application from Grote Industries, LLC (Grote) for an exemption from the requirement that exterior lighting devices on commercial motor vehicles (CMVs) be steady-burning. If granted, the exemption would allow motor carriers to operate CMVs equipped with auxiliary warning lamps controlled by Grote's Rear-End Collision Warning (RCW) system. Following publication of the Agency's notice seeking comment, Grote provided additional information to FMCSA staff concerning the design and operation of the RCW system, including the color and activation sequence of the auxiliary warning lamps, the interaction between the RCW and brake-activated warning functions, system operation on combination vehicles, and the operation of the radar detection system. FMCSA is making this supplemental information available in the docket and provides an opportunity for public comment.
