Accident Report Detail

Long transportation Company, Tractor- Semi-Trailer Collision with Multiple Vehicles

Executive Summary

‚ÄčAbout 7:04 p.m., on August 20, 1976, a tractor-semitrailer descending a steep grade in Valley View, Ohio, collided with 10 automobiles that were stopped at a signalized intersection near the bottom of the grade. Fire ensued. Eight of the 27 automobile occupants died and 15 were injured; the truckdriver sustained minor injuries.

Probable Cause

‚ÄčThe National Transportation Safety Board determines that the probable cause of this accident was the inability of the improperly adjusted and partially inoperative service brake system on the tractor-semitrailer to adequately slow the vehicle as it descended the grade. Inadequate pre-trip inspection by the driver and the lack of required maintenance and inspection by the carrier failed to identify and to correct the unsafe condition of the brake systems. The failure of the road signs to provide advance warning information concerning the length and steepness of the grade and the presence of the signalized intersection, prevented the driver from taking early evasive action.
