Boca Raton, Fl - PM Technology today announced that it has received a patent for an automotive safety system that may have significant value in reducing the frequency and severity of front to back collisions caused by emergency braking and driver inattention. The system consists of micro-electronic circuitry which causes vehicle hazard warning lights to automatically activate under circumstances of rapid deceleration and to remain activated until normal vehicle operation is resumed. In this manner, motorists are provided with the earliest possible warning of excessive slowing by vehicles in front of them and reaction times in applying their own brakes or taking other evasive action are greatly reduced.
