Abstract:
1. A system for providing hazardous road condition warning to a driver of a vehicle and drivers of following vehicles comprising: a temperature sensor for sensing an approximate road surface temperature; a controller interfaced with the temperature sensor for receiving the sensed road surface temperature to detect a hazardous road condition; and an indicator for providing the sensed road surface temperature and hazardous road condition to the driver; a tail light interface, wherein when the hazardous road surface condition is detected the controller automatically produces a tail light signal for activating a vehicle tail light to warn drivers traveling behind the vehicle; and a vehicle engine retardation system interfaced with the hazardous road condition warning system controller for monitoring the engine retardation system and to display retardation system activity to the driver, wherein responsive to the retardation system being used and hazardous road surface conditions are detected the controller automatically produces the tail light signal.
