Abstract
An energy absorption device designed to be mounted on the rear of a high elevation vehicle (e.g. a truck, cargo carrier, trailer or semi-trailer). More particularly, a torsional under-ride guard for use with a high elevation vehicle, which torsional under-ride guard reduces the likelihood that another vehicle will under-ride the high elevation vehicle and absorbs some of the impact energy created when another vehicle collides with the torsional under-ride guard.
