The Idaho State Police are investigating a vehicle roll-over Sunday that left the driver hospitalized. A 27-year-old man from Thayne was eastbound in a Ford pickup on US Highway 26 when he failed to negotiate a curve near the state line, left the road and rolled. The vehicle came to rest on its driver side just off the roadway. The man, whose identity has not been released, was not wearing a seatbelt and was ejected during the incident. He was transported to a local hospital via air ambulance. There is no immediate word on his condition. The Idaho State Police was assisted by the Wyoming Highway Patrol and Alpine EMS.
