Crash cushions or impact attenuators are installed to shield the blunt ends of safety barrier systems. Crash cushions are designed to decelerate an end-on vehicle impact over a short distance and feature energy absorbing cartridges or components. They are designed for attachment to concrete barriers and guardrail systems or may be installed as a standalone system to shield isolated hazards including large poles or sign support structures.
Some crash cushions are classified as non-gating providing redirection of an errant vehicle when impacted at an angle at the nose of the system.
