Abstract: A security device for a motor vehicle is disclosed, having a protective curtain made of a material of sufficient area and strength so that the curtain is able to conceal and prevent the unauthorized use of the motor vehicle's control pedals. The curtain also has sufficient flexibility so that it may be adjusted from a substantially-vertical, closed position, where the control pedals of the vehicle are concealed, to a substantially-horizontal open position where virtually unimpeded access to the vehicle's control pedals, and operation of the vehicle, is possible.
