HIGHWAY ACCIDENT REPORT. COLLISION OF TUBA CITY SCHOOL DISTRICT SCHOOLBUS AND BELL CREEK, INCORPORATED, TRACTOR-SEMITRAILER, US 160 NEAR TUBA CITY, ARIZONA, APRIL 29, 1985

About 3:14 p.m. on 29 April 1985, a tractor-semitrailer transporting cattle and traveling about 59 mph struck the rear of a stopped schoolbus on U.S. 160. Of the 32 schoolbus passengers, 2 were fatally injured, 4 sustained serious inuries, 4 received moderate injuries, 18 sustained minor injuries, and 4 were not injured. The truckdriver and the schoolbus driver received minor injuries. The National Transportation Safety Board determined that the probable cause of this accident was the truckdriver's chronic fatigue, which adversely affected his ability to avoid a collision with the stationary schoolbus; his chronic fatigue developed from a loss of sleep due to a combination of excessive duty time and a prolonged irregular duty pattern. Contributing to the accident was the failure of Bell Creek Incorporated to properly monitor the truck driver's activities to prevent excessive hours of service.
