An apparatus and method for supplementing automotive safety includes a transmitter associated with the traffic safety concerns or conditions such as traffic signals, traffic barricades, or pedestrians. The transmitter is adapted to transmit a signal conveying information indicative of a type or class of traffic safety concern or condition. A receiver is adapted to receive and distinguish the type or class of traffic safety concern or condition. Some type of alarm or display can be connected to the receiver to convey information about the traffic safety concern or condition to a driver. The apparatus and method could also be applied to search and/or rescue missions for persons, animals or objects.
