The Short Answer on Parked Car DUI
A person found in a parked car can face a DUI investigation, but the law still requires driving. California’s main DUI statute makes it unlawful to drive a vehicle while impaired. So a parked car DUI case usually turns on whether the prosecution can prove the person drove.
Vehicle Code section 23152 uses the word “drive” in each of its main subdivisions. Sitting in a car is not the same thing. Yet other facts can show that driving happened earlier.
Facts That Can Suggest Earlier Driving
Officers look for signs that the car moved recently. For example, a warm engine, headlights on or the car stopped in a traffic lane may suggest it. A witness who saw the car moving matters even more.
- Where the car sits, such as a lane, shoulder or parking space
- Whether the engine runs and the keys are in place
- Statements the person made about recent driving
- Witness accounts and video
None of these alone settles the question. Together they may.
A Hypothetical Example
Hypothetical example, invented for illustration: a man leaves a party, feels tired and parks in a grocery lot. He turns the engine off, puts the keys in the glove box and falls asleep in the back seat. An officer later knocks on the window.
Those facts look very different from a car idling in a traffic lane with the driver behind the wheel. Still, the officer will ask when he drove and what he drank before that. His answers may matter more than anything else in the file.
Parked Car DUI and Statements
Statements often carry the most weight. A person who says “I just drove here from the bar” gives the officer evidence of driving and timing. Because of that, the guide on DUI questioning rights covers what people should understand about questions at the scene.
Timing and Test Results
When driving happened earlier, the test result has to connect to that time. Section 23152(b) creates a rebuttable presumption only when a test within three hours after driving shows 0.08 percent or more. So the time of driving matters a great deal.
The article on rising blood alcohol DUI explains why the time of driving and the time of testing can differ.
Sleeping It Off Is Not Risk Free
People sometimes decide to sleep in the car instead of driving home. That choice can avoid driving, yet it can still lead to an investigation. The safest plan is a ride from someone sober.
A parked car DUI case depends heavily on the specific facts. A lawyer reviewing the report and any video can say whether the evidence of driving is strong or weak. The broader guide on delayed DUI arrest situations covers arrests that happen after driving has ended.
