Abstract: A system and method for warning a first vehicle of an approaching second vehicle. The novel system (100) comprises a transmitter system (13) located in the second vehicle (10) for transmitting an electromagnetic signal, and a receiver system (33) located in the first vehicle (20), the receiver system (33) including an antenna (31, 32, 62) for receiving the signal, and a receiver microchip (33) comprising a first circuit (330, 331, 332, 333) for processing the signal and outputting an electronic signal, and a second circuit (334, 339) for generating an audio and/or visual warning signal in response to the electronic signal. In the preferred embodiment, the receiver microchip (33) further includes a third circuit (336, 337, 338) for disabling one or more sound producing sources (44, 54, 35a, 35b) within the first vehicle in response to the electronic signal. In a first illustrative embodiment, the receiver system (33) is implemented as part of a telematics suite or car radio (30).
