The crash happened at 12:48 p.m. along the 15400 block of Clear Spring Road.
The Washington County Sheriff's office said the driver of a 2004 Jeep Grand Cherokee, traveling southbound on Clear Spring Road, lost control of the vehicle, and flipped over. They said the vehicle came to a rest in the upright position.
The 49-year-old male driver was flown to Meritus Medical Center for treatment. Deputies said he was not wearing a seat-belt at the time of the crash.
Speed appears to be the reason for the accident, deputies say.
