Twelve full-scale crash tests were performed at the Department's Highway Safety Test Center to evaluate performance of modifications to the existing cable guiderail breakaway-terminal end. A recent test at Southwest Research Institute using an 1800-lb sedan revealed that in the existing design, cables did not release when a departing vehicle impacted just upstream of the anchor. Three modified anchorage systems were evaluated in accordance with NCHRP Report 230 criteria, with the final design resulting in acceptable performance.
