A control pedal disabling device includes a housing having a side opening or notch for receiving a pedal assembly component. The opening has a forward surface for bearing against the underside of a pedal assembly component. A rod is slidably mounted to the housing. The rod is movable across the opening to trap the pedal assembly component in the opening. The rod is also movable forwardly from the housing to bear against a vehicle floor, thereby preventing movement of the pedal assembly component toward the vehicle floor.
