HIGHWAY ACCIDENT REPORT: COLLISION OF WINNEBAGO MOTOR HOME WITH BRIDGE COLUMN NEAR MONROE, MICHIGAN, JULY 1, 1975
On July 1, 1975, at 10:35 a.m.,e.d.t., a Winnebago motor home traveling south on Interstate 75 ran off the highway and crashed near Monroe, Michigan. The motor home left the roadway, struck the end section of a guardrail, then struck a concrete bridge column, and caught fire almost immediately. The fire which destroyed the vehicle was fed by two 40-pound propane tanks which became detached from the vehicle. Of the 10 vehicle occupants, the driver and a passenger, neither of whom was wearing a seatbelt, were injured when they were ejected through the front of the vehicle. Seven persons perished in the subsequent fire and one was injured but escaped from the vehicle unassisted. The National Transportation Safety Board determines that the probable cause of the accident was the driver's failure to change lanes properly. The escape of propane from the two disconnected gas tanks added to the intensity of the vehicle fire. The Safety Board made recommendations concerning the use of seatbelts, motor home appliances, and propane supply systems.
