Abstract
A crash attenuator includes a crash cushion having a front end, a rear end, and a trailer hitch component disposed adjacent the front end. The trailer hitch component is capable of being secured to a mating hitch component located on the towing vehicle, such that hitch components are capable of being rotated relative to each other about a substantially vertical axis. The crash attenuator further includes at least one wheel supporting the crash cushion. The wheel is rotatable about a substantially horizontal axis and is spaced rearwardly from hitch component. One or more tethers are positioned on opposite sides of the hitch component and are moveable relative to one or more guides connected to the crash cushion.
