A Decatur man was trapped in his car after it rolled several times and landed upside down on the side of the road at 4:30 this afternoon on Farm Road 51 just north of Decatur. Ryan O. Dodson, 26, of Decatur was southbound when for unknown reasons he crossed over onto the oncoming lane of traffic and then into a culvert. The vehicle flipped multiple times end over end. After being freed from the wreckage, Dodson was transported by ground ambulance to Denton Regional. He suffered a head injury in the crash, but it did not appear life threatening. No other vehicles were involved and Dodson had no passengers in his vehicle.
