Monday, there were four roll-over accidents in the northern part of Palo Pinto County. Almost all of those involved did not require medical attention. Monday morning there was a single-vehicle, rollover accident about eight miles north of Graford on Highway 337. "There were five passengers in the truck, but no one sustained any type of injury," said Texas Department of Public Safety Trooper Josh Engleman. "Everyone is being checked out by medical personnel in the ambulances, and all appear to be alright." Graford and Possum Kingdom East EMS units were dispatched to the scene of that accident. He did not say for certain whether the icy roads played a factor in the accident. Additional information on the accident was not available at press time. Near the same area, a truck slid off Highway 337 and rolled down a hill. Once again no injuries were reported. About 12:40 p.m. Monday, there was a one-vehicle rollover on Highway 254 about a mile west of Chaney Lane. No serious injuries were reported in that accident. And about 9:42 p.m. Monday, Graford EMS was dispatched to the scene of another roll over accident on Highway 337 at the top of the hill east of Highway 52.
