Michigan Drunk Driving Case Law
Key Judicial Rulings Defining "Operation" and DUI Standards in Michigan
How Michigan Courts Define "Operating"
In many DUI cases, the central legal question is whether the defendant was actually "operating" the vehicle at the time of the arrest. Michigan case law has evolved significantly, particularly regarding individuals found asleep in stationary vehicles. Krupp Law Offices P.C. leverages over 85 years of experience to apply these precedents to your defense, often identifying grounds for dismissal based on improper definitions of operation.

Lead Michigan Cases
People v. Pomeroy (1984)
The court ruled that a defendant asleep in a motionless car with the engine running but transmission in neutral was not operating the vehicle. This established a critical baseline for "sleeping it off" defenses.
People v. Wood (1995)
In contrast, a defendant asleep at a drive-through with the engine running and the transmission in drive (foot on the brake) was found to be operating the vehicle, as the vehicle was in a position to move immediately.
People v. Burton (2002)
A defendant found asleep in a parking lot with the engine running but lights off was determined not to be operating the vehicle, further refining the "stationary vehicle" standard.
People v. Stephen (2004)
The court found sufficient evidence for OWI where a defendant admitted to driving to a location to sleep, but had struck a parking log while attempting to leave before turning off the engine.
