<p>An FM radio warning system for preventing a second traffic accident is provided to prevent accidents of succeeding vehicles by generating a radio emergency signal at a first traffic accident. An impact sense unit(10) senses the magnitude of impact and outputs an electrical signal to a control unit(11). A warning unit(13) outputs repeatedly a sound message signal of "danger of accident" to an FM radio channel and transmits an emergency radio code signal related to an emergency lamp(16) of a vehicle of a reverse mode. The warning unit turns on automatically emergency lamp of the vehicle when a driver does not turn off a cutoff switch. The warning unit outputs an SOS signal as emergency signal by sounding a horn(14) after a predetermined period.</p> |
