Vehicle mounted crash attenuator

Abstract

A crash impact attenuator for deployment on a construction vehicle includes an energy-absorbing portion, having a backup frame adapted to join the crash impact attenuator to a vehicle, and a sign holder frame extending upwardly from the backup frame. The sign holder frame is adapted to support a first informational sign. Two upwardly extending support posts extend from one of the backup frame and an energy-absorbing portion frame, for supporting a second informational sign forwardly of the sign holder frame, so that the second informational sign is behind the sign holder frame from an approaching motorist's point of view. The support posts may be raised to a display position, with the second informational sign thus being positioned above the sign holder frame, and may further be lowered to a stowed position, so that the second informational sign is positioned behind the sign holder frame.
