  • Method for slowing the progress of a vehicle
    Patent number: 7021859
    Abstract: A safety apparatus for stopping vehicles which depart from the side of a track, has a pool of liquid which extends along and to the side of the track. The pool increases in depth with increasing distance from the track up to a predetermined maximum depth. A crash barrier stops any vehicle which fails to be arrested by the liquid. The pool can be filled and emptied using a pump. A layer of gravel in the pool can be substituted as the vehicle arrest medium by pumping the pool empty. Different depth of liquid can be selected, using the pump. The liquid is preferred to be water, which can be found from rainwater runoff from the track. Such runoff can be pumped away. The invention can be used on both sides of a track.
