Abstract
An auxiliary protection device is attached to the rear of a semitrailer wh resists the tendency of passenger vehicles to go under a trailer upon impact in order to provide an increased measure of safety. In addition, the device to will absorb energy incrementally so as to minimize vehicle damage at low speeds but have sufficient energy absorption to safely prevent incursion at moderate speeds. The device can be moved to a retracted position to allow the trailer to back up a ramp or into a plane with the protection device retracted so as to avoid injury to the ramp.
