Robert J. Penny, 41, of Pantego, was killed this morning when his 18-wheeler, hauling a piece of heavy equipment, ran off of County Road 4599 west of Boyd. According to state troopers, the driver was traveling eastbound about 8 a.m. when he ran off the right side of the road, overcorrected and drove through a fence on the left side. The truck jackknifed, and the driver, who was not wearing a seatbelt, was hurled into the passenger side where he hit his head on an electrical pole by the open window resulting in fatal head trauma.The road is located south of the Texas 114 and Farm Road 51 intersection currently under construction. Penny had just left Cottondale where he was working that morning. Penny’s boss told investigators that the man was probably driving on that road to avoid the construction.
