The Federal Motor Carrier Safety Administration granted a waiver to the National Tank Truck Carriers to allow fleets to install a red or amber brake-activated pulsating lamp in the upper center position or in an upper dual outboard position on the back of tanker trailers, in addition to the steady-burning brake lamps required by federal regulations.
FMCSA granted a similar exemption to tanker fleet Groendyke Transport in April 2019, allowing the carrier to install an amber brake-activated pulsating light in the upper center on the back of tanker trailers in addition to the steady-burning brake lights. Groendyke said over a 30-month period, using the lights reduced rear-end collisions by nearly 34% and eliminated all rear crashes at railroad crossings.
The waiver granted to NTTC allows any carrier using tankers to install the lights. The waiver is effective immediately and is good through Oct. 8, 2025.
