A single car crash in Augusta County has left a teenage girl in critical condition. The accident happened on the 1000 block of Dam Town Road around 7:00 a.m.

Virginia State Police say, with no skid marks and no other car, there's no evidence of what caused the girl to crash.

Police speculate the girl may have fallen asleep at the wheel. She was driving on Dam Town Road, struck a tree and wound up on the other side of the road.

The jaws of life were used to remove the 16 year old from the wrecked Toyota. Chains attached to a tree were used to raise the car and allow crews access to the girl.

She was airlifted to the University of Virginia Medical Center.

Police say the road is heavily traveled.

Virginia State Police Master Trooper Kenneth Hyden says, "Unfortunately, this is a main stretch of road from the Fort Defiance High School to the Crimora/New Hope area, where a lot of students drive. Therefore, when you have a lot of students driving their cars, you're going to have a lot of accidents."

Police say, with all the hills, twists and turns in the road, this area has a history of being difficult to navigate.

They say, had the victim been wearing a seat belt, her injuries may not have been as severe.

State police confirm the girl is a student at Fort Defiance High School. They say reckless driving charges may be filed.
