Does the car have to be moving for me to be guilty of DUI?

No — in Pennsylvania, a vehicle does not need to be in motion for a DUI charge to apply. This is one of the most frequently misunderstood aspects of Pennsylvania’s DUI law, and it has resulted in convictions for drivers who believed they were acting responsibly by sitting in a parked car rather than driving while impaired.

Pennsylvania’s DUI Statute: “Actual Physical Control”

Pennsylvania’s DUI statute, codified at 75 Pa. C.S. § 3802, prohibits an individual from driving, operating, or being in actual physical control of the movement of a vehicle while under the influence of alcohol or a controlled substance. The key phrase is “actual physical control” — a standard that extends well beyond actively driving a moving vehicle.

What “Actual Physical Control” Means

Pennsylvania courts have interpreted actual physical control broadly, focusing on whether the defendant had the capability and power to put the vehicle in motion — not whether they were actually doing so at the time of the encounter with police. Courts consider a combination of factors, including:

• Whether the defendant was in the driver’s seat
• Whether the keys were in the ignition or readily accessible
• Whether the engine was running
• Whether the vehicle was in gear or in park
• Whether the vehicle was on a public highway or private property
• The physical and mental condition of the driver
• Whether there was evidence the vehicle had recently been driven

No single factor is determinative. A person found asleep in the driver’s seat with the engine running and the keys in the ignition is in a very different position than a person asleep in the back seat with the keys in their pocket — though both scenarios have produced DUI charges in Pennsylvania.

Common Scenarios That Lead to Charges

Several real-world situations commonly give rise to DUI charges even without active driving in Pennsylvania:

• Sleeping it off in the car: A person who decides to sleep in their vehicle rather than drive after drinking may be charged if they are in the driver’s seat with the keys accessible and the engine running for heat or air conditioning.
• Pulled over voluntarily: A driver who pulls to the side of the road after realizing they are impaired and turns off the engine may still face DUI charges based on evidence that they drove to that location while impaired.
• Moving a vehicle a short distance: Moving a car from one parking space to another, pulling in or out of a driveway, or otherwise operating a vehicle for any distance can support a DUI charge.
• Keys in the ignition while parked: Sitting in a parked car in the driver’s seat with the engine running — even in a private parking lot — may constitute actual physical control under Pennsylvania law.

Chemical Testing and the Implied Consent Law

Pennsylvania’s implied consent law — 75 Pa. C.S. § 1547 — requires drivers to submit to chemical testing when lawfully requested by a law enforcement officer who has reasonable grounds to believe the person was driving, operating, or in actual physical control of a vehicle while under the influence. A refusal to submit to chemical testing carries penalties equivalent to the highest BAC tier for DUI sentencing purposes and results in an automatic license suspension — regardless of whether the person is ultimately convicted of DUI.

Defending Against Non-Driving DUI Charges

Cases involving parked vehicles and “actual physical control” present distinct defense opportunities. The totality of the circumstances — where the keys were, whether the engine was running, what the defendant’s stated intentions were, and the specific location of the vehicle — all bear on whether the prosecution can establish actual physical control beyond a reasonable doubt. These factual nuances make experienced DUI defense counsel particularly important in non-traditional DUI scenarios.
