You might think that sleeping off a night of drinking in your car protects you from a DUI charge. In South Dakota, however, you can face a DUI not only for driving while impaired but also for having “actual physical control” of a vehicle.
What does “actual physical control” mean?
Actual physical control can apply even when a vehicle is not moving. The central question is how your position, access to the controls and surrounding circumstances affected your ability to operate the vehicle in its ordinary manner.
Courts may consider details such as:
- Whether you are sitting in the driver’s seat
- Whether the vehicle is operable
- Whether you can reach the vehicle’s controls
- Whether the keys are accessible
- Whether the engine is running
- Whether someone else can control the vehicle
Rather than treating any single detail as conclusive, the court evaluates how these circumstances collectively reflect your ability to control the vehicle.
Can the engine be off?
Yes. An engine that is off does not automatically rule out actual physical control, and the keys do not necessarily have to be in the ignition. What matters more is your position and ability to control and operate the vehicle when officers found you.
Does anyone have to see you drive?
No. The state does not have to prove that you actually drove the vehicle if it can establish actual physical control. It also does not have to show that you specifically intended to drive. The focus remains on your position, access to the vehicle and ability to operate it under the circumstances.
Why the details matter after a parked-car DUI arrest
A parked-car DUI charge can depend on details that may not seem important at first, including where you were found, who had access to the vehicle and what officers observed. Those facts can shape how the state evaluates the charge.
Understanding which facts matter can help clarify how South Dakota law applies to a parked-car DUI. A legal review can also help assess the strength of the state’s claim of actual physical control.
