The accused was charged with care or control of a motor vehicle while impaired and operating a vehicle with a blood alcohol level over 80 milligrams.
He was found slumped over the steering wheel of a parked car with the engine running.
The accused conceded impairment but argued he lacked care or control because there was no realistic risk of danger.
The court acquitted the accused, finding that the vehicle was safely parked, the emergency brake was engaged, and there was no risk of accidental transmission engagement.
