A steering wheel has an integral arm D which extends from the rim A of the wheel, and is held in the extended position by a lock C, to prevent the wheel rotating. Access to the nut B holding the wheel to the steering column is blocked, to prevent the wheel being removed. Further, when the arm is extended the steering wheel may become free spinning to prevent the vehicle being steered. Embodiments are described with more than one arm, and in which the wheel rim is split to expand. |
