The invention is a proactive collision avoidance system. The system comprises a first paired set of a transmitter effective for transmitting a radio signal and a receiver effective for receiving a radio signal from a limited distance, a means for preventing the receiver in the first paired set from receiving the radio signal transmitted by the transmitter in the first paired set while permitting the receiver in the first paired set to receive a radio signal transmitted by a transmitter in a second paired set, and a means in electrical communication with the receiver in the first paired set for generating a perceptible signal upon receipt of the radio signal from the second paired set.
