Abstract
A system adapted to provide a warning to a vehicle operator of nearby hazards, e.g., that a nearby vehicle has been in a collision or is otherwise inoperable. Embodiments include a detector operable to detect a hazard, a transmitter to transmit a warning signal, a receiver to receive a transmitted warning signal, and a display to warn the operator of an approaching vehicle of the hazard. Some embodiments incorporate feedback from a vehicle's airbag deployment circuitry to provide a trigger effective to broadcast the warning signal. The operator of an approaching vehicle may be provided with a visual and/or an audible warning signal, e.g., via a cellular telephone. Certain embodiments provide such warning to approaching vehicles via the transmitted warning signal and a display and/or speaker carried in the approaching vehicle. Audible and visual warnings may be transmitted directly from the crashed vehicle.
