AbstractA vehicle monitoring apparatus includes a rear video camera mounted on a rear portion of a vehicle, a right video camera mounted on a right sideview mirror, a left video camera mounted on a left-sideview mirror, a mirror-effect circuit connected across two poles of a pair of horizontal deflection coils of a horizontal deflection add oscillation circuit of a television receiver electrically connected to the video cameras for inverting an image or picture orientation to be the same as an orientation of the real subject positioned at a rear side of the vehicle, whereby upon a backing, a rightward turning or a leftward turning of the vehicle a corresponding video camera will be initiated to transmit a "picture" of the subject positioned at the rear side of the vehicle to display a picture on a television placed in the vehicle having a same orientation of the picture as that of the true subject for preventing an accidental collision due to falsely backing or turning of the vehicle for driving safety.
