Each of a plurality of motor vehicles is equipped with a transmitter (1) and a receiver (2) for transmitting and receiving electromagnetic or pressure waves, detector devices (30-40) arranged to output electrical signals indicative of predetermined travelling conditions of the motor vehicle, signalling devices (6) for providing the user with perceptible messages or signals, and an electronic processing and control unit (3). The latter is arranged to assume automatically a first mode of operation when the detector devices (30-40) indicate the occurrence of one of the said travelling conditions; in this case the unit (3) automatically activates the transmitter (1) which transmits signals of a first type containing information indicative of the travelling condition detected; a second mode of operation when the receiver (2) picks up signals of the first type emitted by the transmitter (1) of another motor vehicle, in which case the unit (3) activates automatically the transmitter (1) to transmit signals of a second type, the information content of which includes the information content of the signals of the first type picked up by the receiver (2). The processing and control unit (3) is also arranged to activate the signalling devices (6) automatically each time the receiver (2) picks up signals of the second type in order to provide the user with signals or messages corresponding to the information content of the signals of the second type picked up by the receiver.
