INFINITI pioneered Lane Departure Warning on the 2005 INFINITI FX, designed to help address the National Highway Traffic Safety Administration's (NHTSA) findings that showed more than half of all traffic fatalities were due to some type of lane departure. INFINITI then expanded and enhanced its warning system with the world's first Lane Departure Prevention system on the 2008 INFINITI M, which helps the driver bring the vehicle back into the lane of intended travel.
