Executive Summary

Harmon and Sons, Inc. was eastbound on II-70 transporting 13 high school students to their homes in St. Louis, Missouri, from the Parkway North Senior High School. As the schoolbus was approaching the Lucas and Hunt Road exit it went out of control, swerved to the right, and the right front of the schoolbus struck a guard rail, a concrete pedestal and a sign support pillar located adjacent to the right eastbound roadway. The schoolbus body and the steering axle separated from the chassis during the collision. The weather was cloudy and the pavement was dry. The schoolbus did not catch fire. Two students were killed; the schoolbus driver and one student sustained serious injuries and the remaining 10 students sustained minor to moderate Injuries.


Probable Cause

‚ÄčThe National Transportation Safety Board determines that the probable cause of this accident was the operation of the schoolbus at an excessive speed and in a reckless manner by a driver under the influence of alcohol. Contributing to the severity of the accident was the use of a guard rail of insufficient height and stiffness to deflect the schoolbus bodyaway from the concrete pedestal and sign support pillar.
