FMCSA takes comments on radar-triggered rear warning lights through Nov. 19
FMCSA is taking comments through Nov. 19 on Grote Industries' request to let trucks use rear lamps that pulse amber when radar senses a fast-closing vehicle.
What happened
FMCSA published new details on Oct. 20 about Grote Industries' request to let trucks use rear warning lamps that pulse when radar senses a vehicle closing fast from behind. Grote now says the lamps pulse amber for up to four seconds and do not turn steady red; any steady red comes from braking. Comments on the new details are due Nov. 19.
Why it matters
Federal rules generally require exterior lamps on trucks to burn steady, so this kind of warning needs an exemption. CVSA had raised concern that following drivers could read steady red as braking. If granted, the five-year exemption would allow carriers to use the system, not require it.
