ABSTRACT:
When a post 10 is hit by a car in the direction indicated by arrow 42 the post moves a restricted amount in the direction of that arrow and that movement causes a support member 34 to be lifted up to raise the front wheels of the car off the ground. A plate 58 is secured to the underside of the support member 34 and, during raising of the support member 34, the plate passes over a series of notches 56. However, the plate 58 abuts those notches 56 to prevent the support member 34 moving downwardly again.
