Vermont State Police say a preliminary test indicates a Wells woman was extremely impaired before her car traveled downhill in reverse and crashed into a rock.
Police said a preliminary breath test Saturday night indicated the driver's blood-alcohol content was 0.362 percent - more than four times the legal limit.
State Police say Granville Rescue transported 45-year-old Tracy Davies to the hospital because she appeared to be going in and out of consciousness.
Police said they processed Davies on suspicion of driving under the influence of alcohol and that a blood sample has been provided for analysis. The Associated Press couldn't find a phone number for Davies. It was unclear if she had a lawyer.
