Abstract
The operator of a third vehicle trailing a second, host vehicle is alerted of a potentially hazardous deceleration of a first vehicle forward of the host vehicle. The road-speed of the first vehicle is ascertained by the host vehicle. Any significant deceleration of the road-speed of the first vehicle is determined. A luminous signal is provided to the third vehicle by the host vehicle when such significant deceleration has occurred. According to some methods a radar device carried by the host vehicle may be used to determine the relative speed between the first and second vehicles.
