Abstract: A vehicle braking alert system installed in a vehicle comprises a receiver installed at a head portion of the vehicle for receiving signals from a front vehicle; and transferring the received signals; a transmitter at a rear end of a vehicle for emitting signals to a vehicle behind the vehicle having the transmitter; a braking indicator at a rear side of the vehicle; and a signal processor receiving signals transferred from the receiver for determining to cause the transmitter to emit signals or cause the braking indicator to light up. By above components, when a first vehicle installed with the vehicle braking alert system brakes, the transmitter will emit signals to a second vehicle behind the vehicle and installed the vehicle braking alert system; the second vehicle receives the signals from the first vehicle so as to light up the braking indicator at the rear side thereof to alarm another vehicles.
