The report describes and analyzes an accident involving a schoolbus-type bus which ran off the roadway while attempting to negotiate a right angle turn and vaulted into a farm drainage ditch. The bus came to rest on its left side, partially submerged. Nineteen of the 47 occupants, including the driver, died in the accident. For each fatality, the cause of death was drowning. The National Transportation Safety Board determines that the probable cause of this accident was the failure of the driver to reduce the speed of the bus to that required to negotiate the turn, despite the presence of a turn warning/advisory speed sign. Contributing to this failure was a lack of driver alertness induced by fatigue.
