Abstract: An electronic encoder/transmitter encodes acoustic and visual signal pulses for transmission to other vehicles. A device transmits alarm signals instantaneously when the vehicle self collides, becomes blocked in the road, or when the vehicle is on a collision course with another vehicle. The device receives signals from sensors and enters a function to send an encoded radio signal via an antenna. A manual switch may also be used. Signals received by the decoder/receiver may be visualized by colored LEDs placed at a front panel. The transmitted signal is sent to all vehicles driving in the immediate area. The present invention includes acoustic and visible pulses to warn of risks and collisions which may happen in a short distance and not be visible between the vehicles. The present invention also includes an alarm placed on all four sides of the vehicle and connected to an automatic hydroelectric brake system for reducing the speed of the vehicle.
