Abstract:
A warning system and methods for vehicles traveling in tandem. A signal beam of energy is emitted from a leading vehicle and is directed toward the roadway to indicate a safe stopping distance. The signal beam is automatically displaced in response to changes in vehicle speed to indicate a new safe stopping distance. The signal emitter may comprise a lamp for emitting a visible light beam. A signal detector may be provided on the trailing vehicle to detect the energy beam from the leading vehicle.
