The Federal Motor Carrier Safety Administration (FMCSA) is granting National Tank Truck Carriers Inc.’s (NTTC) application for a limited five-year exemption to allow tank trailer operators to install a red or amber brake-activated pulsating lamp in the upper center position or an upper dual outboard position on the rear of the trailers, in addition to the steady-burning brake lamps required by federal regulations. FMCSA has determined that “granting the exemption would likely achieve a level of safety equivalent to or greater than the level of safety provided by the regulation.” This exemption is applicable through Oct. 8, 2025.
