Following a 30-month study that ended last year, Groendyke Transportation learned that the addition of a relatively simple, pulsating amber brake light reduced rear-end collisions by roughly 34%.
The Oklahoma-based hazmat hauler had received an exemption from the Federal Motor Carrier Safety Administration (FMCSA) to mount the light on the back of 632 of its tanker trucks, and in two-and-half-years they saw a 33.7% drop in rear-end crashes along with the elimination of all railroad crossing rear-end accidents.
A reduction like that in accidents caught the attention of safety experts at the FMCSA which is now expected to grant an exemption for amber pulsating brake lamps on all tank truck carriers.
