Crash cushion's main function is to absorb the kinetic energy cased by vehicle collisions and to protect the safety of the passengers.

Crash cushion with soft energy absorbing structure front, then increases sequentially its hardness, so that increases its capability of energy absorption.

When vehicles crash energy-absorbing triangular crash pad straightly, bracket will slide along the guide rail, Waveform slab shrinks and folds, absorbs collision energy so that make the vehicle safely stop.

When vehicles side crash, the guide rail will restrain crash pad lateral movement, guardrail will expand deformation to absorb collision energy, but also plays a good role in guiding vehicle turn to the correct direction of travel.
