Two types of guide rail end terminals were constructed and evaluated according to the American Association of State Highway Transportation Officials' (AASHTO's) Manual for Assessing Safety Hardware (MASH). The guide rail end terminals are used with weak-post, box beam guide rail systems by the New York State Department of Transportation (NYSDOT). Nine full-scale vehicle crash tests were performed in accordance with either Test Level 3 (TL-3) or Test Level 2 (TL-2) requirements using both standard and modified impact locations and test conditions for the 1100C [1,100-kg (2,425-lb)] passenger car and the 2270P [2,268-kg (5,000-lb)] pickup truck. One test was run on the Type II box beam end terminal, six tests were performed on the Type IIA end terminal on flat ground, and two tests were performed on the Type IIA end terminal installed in a ditch. The Volume I report contains the research results and discussion. The Volume II report contains the appendices.
