Smart Cushion

The World’s Only Speed-Dependent Crash Attenuators


The Smart Cushion® crash attenuator is a revolutionary, speed-dependent product that varies stopping resistance during an impact. The Smart Cushion™ crash attenuator allows lighter and slower-moving vehicles to have longer ride down distances and lower ride down g-forces.


Unlike fixed-resistance attenuators, the Smart Cushion® attenuator does not reach maximum stopping resistance unless a vehicle is traveling at the maximum design speed. This fully re-directive, non-gating, bidirectional, impact attenuator was designed for maximum safety and reusability, as well as outstanding durability before, during, and after an impact.


The SLED is designed to shield the end of all permanent and temporary portable barrier shapes including concrete, steel, and plastic. SLED's unique design incorporates four internal steel cables which help envelop the impacting vehicle, reducing the possibility of secondary accidents. The SLED End Treatment does not require foundation anchor bolts to be attached to the road or bridge deck. The complete crash cushion can be installed quickly, with as little as one pick up truck and two workers on compacted dirt, gravel, decomposed granite, asphalt, or concrete.
