Most people associate DUI arrests with traffic stops or erratic driving. However, California DUI laws can apply in situations where no officer actually witnessed a person driving. Individuals have been charged after being found asleep inside a parked vehicle or stopped on the side of the road with no direct evidence that the car was moving.
These cases can carry serious legal consequences, and the legal issues involved are often more complex than many people realize.
In this guide, we explain how California law defines “driving” under DUI statutes and how a California DUI defense attorney can help if you have been charged without being seen behind the wheel.
What Counts as “Driving” Under California DUI Law?
California Vehicle Code § 23152(a) makes it unlawful for a person under the influence of alcohol or drugs to drive a vehicle. Vehicle Code § 23152(b) separately prohibits driving with a blood alcohol concentration (BAC) of 0.08% or higher, with stricter limits applying in certain situations.
Both statutes depend on one critical element: driving.
In Mercer v. DMV (1991) 53 Cal.3d 753, the California Supreme Court held that “driving” requires proof of volitional movement of the vehicle. This means prosecutors must show that the vehicle actually moved, even if only a short distance.
Unlike some states that use an “actual physical control” standard, California generally requires evidence of movement rather than simply proving a person was sitting inside the vehicle while intoxicated.
However, prosecutors may rely on circumstantial evidence to prove movement occurred, even when no officer directly observed the vehicle being driven.
Can You Be Charged With a DUI While Parked or Sleeping in Your Car?
Potentially, yes. Being asleep in a parked car does not automatically prevent prosecutors from filing DUI charges in California. While the prosecution still must prove that you drove while impaired, they often attempt to establish this through indirect or circumstantial evidence.
Law enforcement officers commonly look for signs suggesting the vehicle was recently operated. Factors prosecutors frequently rely on include:
- A warm or running engine at the time of contact
- Keys in the ignition or the vehicle powered on
- The driver positioned behind the wheel with the seat adjusted for driving
- The vehicle’s location, such as on a roadway or in a position inconsistent with being parked from the outset
- Witness statements or surveillance footage
- Admissions made during police questioning
Even without direct proof of driving, prosecutors may argue that the surrounding circumstances strongly suggest the vehicle was driven while the driver was impaired.
Why These DUI Cases Can Be Challenging
DUI cases involving parked or stationary vehicles are often highly fact-specific. The prosecution may rely heavily on assumptions and circumstantial evidence rather than direct observations.
For example, prosecutors may attempt to argue:
- The vehicle was recently driven because the engine was warm
- The driver intended to continue driving
- The individual pulled over after already driving under the influence
An experienced California DUI defense attorney can challenge these assumptions and examine whether the evidence actually establishes movement beyond a reasonable doubt.
