ABSTRACT:
An energy-absorbing guardrail terminal has a plurality of beams, extending substantially parallel to one another, and having at least one overlapping end; a plurality of break-away support posts coupled to and supporting the plurality of beams; a plurality of fasteners for coupling the plurality of beams to one or more of the plurality of break-away posts; and an arrangement for creating a substantially square wave of energy absorption during telescoping of the plurality of the plurality of beams during a forceful impact of a vehicle on the energy absorbing-guardrail terminal. The substantially square wave of energy absorption during telescoping may be created by a plurality of openings formed on the plurality of beams that are operable to encounter a plurality of fasteners during a forceful impact by a vehicle on the energy absorbing guardrail terminal. A method of manufacturing an energy-absorbing guardrail terminal is also provided.
