Parts and Accessories Necessary for Safe Operation; Metronet Application for Exemption

FMCSA requests public comment on an application from Metronet for an exemption from the requirement that all exterior lighting devices be steady burning. The exemption would allow Metronet to use Grote Industries LLC's (Grote) amber brake-activated pulsating lamp on its commercial motor vehicles (CMVs), including pickup truck service vehicles not covered by the exemption FMCSA previously granted to Grote, in addition to the steady-burning brake lamps required by the Federal Motor Carrier Safety Regulations (FMCSRs).
