System for warning of traffic incidents, especially the approach of emergency vehicles, comprising a radio transmitter adapted to be positioned in a first vehicle, e.g. an emergency vehicle, and a radio receiver adapted to be positioned in a second vehicle. Said transmitter is adapted to emit radio frequency pulses within a chosen frequency range, at chosen intervals being substantially longer that the duration of the pulses, and said receiver is adapted to receive radio signals within said chosen frequency range and to detect the occurrence of said pulses, the receiver also comprising means for visually or audibly indicating the detection of said signals.
