An impact attenuation system which uses vertically standing, hollow, cylindrical energy dissipators (16, 18) having ellipti- cal shaped cross sections. The cylindrical energy dissipators (16, 18) can be used in connection with prior art impact attenuation systems which used round cylinders. In one application, the protected structure is a truck (12) and the system is attached to the truck (12) by a series of brackets (32). A brace (34) is pivotally attached to the bracket (32) and a plate (36) is attached to the brace (34). One or more elliptical cylinders (16, 18) are attached to the plate such that the minor diameters of the elliptical cylinders run substantially parallel to the plate and the major diameters of the elliptical cylinders (16, 18) run substantially perpendicular to the plate. A radial slit (50) is cut out of the rear most cylinders (18) proximate to the top and the bottom. The slits (50) are arcuate and extend substantially about the back half of the rear-most cylinder (18).
