This report identifies factors which might be related to vehicles going over the roadway embankment, locations of over-embankment accidents, and roadway/roadside characteristics where these accidents occur. Recommendations which might reduce the potential for over-embankment accidents are provided. The scope of this research was limited to rural 2-lane conventional highways. It was determined that only 11% of the over-embankment accidents occurred at concentrated locations (less than 0.5-mile apart). Most of these locations had numerous curves with little or no shoulders and trees or water in the roadside environment. Countermeasures that might reduce the potential for over-embankment accidents in general include installing new guardrail near cut-slope areas and burying guardrail into the cut-slope, providing additional signing and striping, improving the shoulder, installing rumble strips, installing audible edge stripes, or cleaning up the roadside environment to provide a clear recovery area. Individual locations should be investigated to determine whether a safety project is warranted and to determine what countermeasures, if any, should be applied.
