On Sunday, June 9, 2002, about 5:10 a.m. central daylight time, near Loraine, Texas, a 1993 Motor Coach Industries MC-12 motorcoach, operated by Greyhound Lines, Inc., (Greyhound) and occupied by the driver and 37 passengers, was traveling east on Interstate 20 (I-20), on a scheduled route from El Paso, Texas, to Abilene, Texas, at a driver-reported speed of 65 to 67 mph. A truck tractor-semitrailer, consisting of a tractor and a semitrailer leased by DelCar Trucking (DelCar), which was being operated by a driver in training with a codriver in the sleeper berth, was entering the interstate from a picnic area at a driver-estimated speed of 40 mph and proceeding into the eastbound lanes. The motorcoach collided with the rear of the semitrailer near milepost 228 of Interstate 20, pushing the tractor-semitrailer approximately 276 feet. Three passengers on the Greyhound bus, all seated in the front of the bus, were fatally injured. Five passengers and the busdriver were seriously injured. Twenty-four passengers sustained minor injuries, and five passengers were uninjured. The truckdriver sustained a minor injury, and the codriver was uninjured.
