The state of Viriginia has reported good results with highway "crash cushions" installed at 48 locations in the state. Virginia evaluated three types of crash cushions. Crushable plastic barrels containing strategically placed air spaces and varying amounts of sand; hydraulic cushions; and, crushable cartriges made up of crushable concrete cannisters with fender panels. The Virginia evaluation involved 50 crashes into the cushions. 10 were investigated by the police and 40 were hit-and-run. The cushions were installed at the 48 sites for a total of about $500,000. The most costly were the crushable cartriges and the least costly were the sand barrels. The only significant problems were debris scattered by impacts with the sand barrels and occasional "ramping" of vehicles on debris they were pushing ahead of them.
