Abstract
A crash cushion apparatus broadly comprising a rail assembly, a number of dividers and a number of side panels forming a number of collapsible bays, and a number of crushable tubes. The rail assembly includes a number of anchor plates and a rail. The dividers are longitudinally spaced apart from each other and slidably entrained on the rail. The side panels link the dividers together. The crushable tubes are oriented longitudinally in spaces formed by the collapsible bays and extend between sequentially adjacent ones of the dividers. The dividers entrain the crushable tubes in the longitudinal orientation without the crushable tubes being fixed to the dividers. The dividers are configured to be driven rearward along the rail and crush the crushable tubes to sequentially collapse the collapsible bays.
