Didn't see it happen, but it must have only been seconds before I came across it, young lady apparently blacked out and ran off the interstate, we saw the back end of her car sticking out of the trees as we passed. She stated that she'd started feeling woozy and was starting to slow down and get off the interstate and the next thing she remembered was waking up with her car in the trees. No injuries and not a lot of damage to the car. Like most young people these days, she called her dad instead of 911, my wife and I stuck around until her dad got there, after she'd been checked out by the paramedics. She was in the ambulance so I don't think she knows that the state trooper did a quick search of her car checking for any drugs that might have been a factor in her blacking out.
