Abstract: A vehicular control pedal disabling device having a base member, a generally U-shaped member extending upwardly from the base member, a structural housing through which the U-shaped member slides, and a means to lock the device. A means for producing light can be attached to the device to make it more noticeable to those outside of the vehicle. In the device's operable position, the U-shaped member and the structural housing surround the stem of the control pedal and prevent the pedal's actuation when the device is locked. In one embodiment the structural housing includes a support sleeve, a pedal restricting member, a first guide sleeve, a second guide sleeve and a connecting member. The first guide sleeve is connected to the support sleeve through the pedal restricting member and the first guide sleeve is parallel with the support sleeve. The second guide sleeve is axially aligned with the first guide sleeve so that the U-shaped member can slide through both the first and second guide sleeves.
