The report describes a study of run-off-road, over embankment, and guardrail accidents together with their respective accident severities. Results indicate that guardrail for the protection of roadside development is not justified unless the accident potential is high and the consequences of involvement are very large. On-site review of 775 over embankment accidents was used to obtain data on embankment height and slope. These data and accident severities were used in multiple regression analyses to develop an equal severity curve for comparing the severity of striking guardrail with the severities of going over embankments having various combinations of slopes and heights.
