MARYLAND TURNED-DOWN GUARDRAIL TERMINAL. FINAL REPORT

Since the late 1960's the Maryland State Highway Administration has used the turned-down terminal on its guardrails. In the late 1960's the California Division of Highways and Southwest Research Institute conducted several tests which indicated this turned-down terminal could potentially launch an impacting vehicle and cause it to roll over. A relatively simple method of modifying the turned-down end guardrail terminal has been developed which will eliminate or greatly minimize the probability of a vehicle ramping and rolling over. Two different designs were developed and evaluated by full-scale vehicle crash tests.
