Abstract

The signal has a range restricted to the distance at which it is required to warm the driver of an approaching vehicle, with reference to the direction of the approaching traffic. The signal is used to initiate an audio and/or visual indicator to warn the driver. This vehicle the emits a similar radio signal to that received, so as to warm the vehicle behind, which in turn relays the signal to following traffic.
