Deputy Chad Scott lost control of his vehicle while traveling along Pulley Town Road between Fowler and Mitchell Mill roads around 6:20 p.m., troopers said. Scott was responding to a call at the time, but troopers were not sure what type of call.
The patrol car went off the right side of the road, and Scott over-corrected, sending the car over the center line and off the left side of the road. The car then went into a ditch and flipped over, troopers said.
Scott complained of abdominal pain and was taken to WakeMed, officials said. He was treated for minor injuries and released.
Pulley Town Road was closed for about an hour while the accident scene was cleared.
The state Highway Patrol continued to investigate the wreck Thursday night.
