Abstract: Manually positioned wheel chocking apparatus are disclosed. In a preferred embodiment, the chocking apparatus includes a track secured adjacent a parking area; a movable chock; and means for temporarily fixing the chock to the track to substantially prevent the chock from moving. The movable chock has a surface which can be selectively positioned within the parking space at a location for engaging a tire of a vehicle. It also includes an extension for operatively engaging the track. The fixing apparatus may optionally comprise a pin sized to mate with a bore in a track or a frictional lock, preferably constructed as an over-center toggle.
