How Drunk Was He? See For Yourself.
The good news? No injuries. The bad news (for this young man, anyway - good for the rest of us)? This young man is in the soup. As reported by the Hunterdon County Democrat (New Jersey):
Police responded to a report of a suspicious vehicle on Route 523 in Readington. The vehicle was found to be in reverse, with the engine running, and when police nudged [Matthew] Kelly  to see if he was awake, the man’s foot slid off the brake pedal and the vehicle rolled backwards into a tree.Yikes. Surely that must have awakened him?
Kelly was still asleep after striking the tree, police said.Police did manage to awaken him, after which he was ...
...charged with careless driving, driving while intoxicated and being under the influence of a controlled dangerous substance.Here's the source.
