Test level three (TL-3) is probably the most common as it establishes safety criteria for both small cars and pickups at 60 miles per hour (97 km/h). This category of traffic accounts for the majority of all vehicle traffic in ...
An impact attenuator, also known as a crash cushion, crash attenuator, or cowboy cushion, is a device intended to reduce the damage to structures, vehicles, and motorists resulting from a motor vehicle collision. Impact attenuators are designed to absorb the colliding vehicle's kinetic energy.
