Accident Report Detail

Median Crossover, Collision, and Fire, U.S. Highway 75

Executive Summary

‚ÄčOn September 20, 2004, about 4:29p.m. central daylight time, a 1999 Freightliner truck tractor, in combination with a 1997 Trailmobile dry van semitrailer, traveling northbound on U.S. Highway75 (US75), in the city of Sherman, Grayson County, Texas, crossed the median and collided with a 2000 Ford Expedition sport utility vehicle (SUV) and a 1990 Ford F150 pickup truck traveling southbound on the same road. A postaccident fire ensued. The Freightliner was driven by a 45-year-old man en route from Dallas, Texas, to Kansas City, Missouri. The weather was cloudy, and the roadway was dry.

Probable Cause

‚ÄčThe National Transportation Safety Board determines that the probable cause of the September 20, 2004, median crossover accident near Sherman, Texas, was the Freightliner driver's startle response consisting of a sudden and sharp over control maneuver to the left in an unnecessary reaction to vehicles that were traveling a safe distance ahead of the truck, caused either by the driver's significant lack of sleep, which resulted in a brief period of sleep or attention loss while driving, or by the driver's attempted or imminent use of a wireless device, which distracted him from his driving duties. Contributing to the severity of the accident was the use of a pickup truck cargo area bed to transport passengers despite its lack of any occupant restraint system.
