On 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.
