Abstract: A chock for a vehicle wheel comprising a first plate, having a series of swaged down portions to rigidify the plate and to grip a roadway, a second, flexible plate welded at one end to said first plate, and a pin engageable in a hole at the other end of each plate, to deform the flexible plate to a curved shape, which conforms to the shape of a vehicle wheel. The pin can be removed and the chock flattened to a folded condition, with the pin then being placed in a slot in the flexible plate.
