Abstract

An anchorless crash cushion apparatus having a plurality of interconnected water-filled crash cushion elements and a non-water filled forward-most cushion element includes vehicle capture structure resisting upward tilting of a frontally impacting vehicle and ramping of the frontally impacting vehicle and stabilizing structure resisting relative rotation between the crash cushion elements in both vertical and lateral planes during vehicle impact. External elongated deformable structural members extend along the sides of the crash cushion elements and bend outwardly away from the crash cushion elements during frontal vehicle impact.
