The Federal Motor Carrier Safety Administration (FMCSA) has granted an exemption request from Groendyke Transport Inc. that allow the company to install amber brake-activated pulsating lights on the back of its trailers.

Such lights are normally prohibited for non-emergency vehicles. The exemption also preempts state laws that would interfere with operating under its terms in interstate commerce while encouraging states to adopt similar exemptions for intrastate commerce, according to the National Tank Truck Carriers (NTTC) trade group.

โ€œGroendyke demonstrated that installing these lamps on 632 of its trucks reduced their rear-end collisions by 33.7 percent,โ€™โ€™ NTTC said in a press release. โ€œThis eliminated all highway-rail grade crossing rear-end crashes in a 30-month period.โ€™โ€™

FMCSA did not extend the exemption to all similarly-situated motor carriers, despite noting that โ€œlarge trucks are three times more likely than other vehicles to be struck in the rear in two-vehicle fatal crashes.โ€™โ€™

โ€œNTTC celebrates Groendykeโ€™s victory,โ€™โ€™ the organization said. โ€œBut, our twin safety and industry-support missions compel us to officially petition that FMCSA and the National Highway Traffic Safety Administration update the FMCSA standards and allow all motor carriers to achieve similar safety gains.โ€™โ€™
