On May 9, 1975, a 1972 schoolbus carrying 20 persons crashed through a section of guardrail on the northbound portion of Interstate 5 in Ashland, Oregon. The vehicle fell down a steep slope and rolled about its longitudinal axis before it came to rest in an upright position about 213 feet from the edge of the pavement. Except for one sidepost-roof bow connection, the roof separated from the bus body. Nineteen of the 20 occupants were ejected; 3 were killed and 15 were injured. The only occupant who remained in the bus was not injured.
