Every DUI charge has an element people forget about: the prosecution has to prove you were actually driving. When no officer saw the car move, that is not always easy, and it is one of the first things I look for. I am Joel Brand, and the no-driving defense quietly wins more cases than people expect.
Driving has to be proven beyond a reasonable doubt
Under Vehicle Code 23152, the state must show you drove the vehicle. This is a separate element from intoxication, and it has to be proven beyond a reasonable doubt just like everything else. California law generally requires evidence of volitional movement of the car, however slight. Merely sitting in a stationary vehicle is not, by itself, driving. The seminal California case on this point, Mercer v. Department of Motor Vehicles, made clear that "driving" ordinarily requires evidence that the vehicle actually moved under the driver's control, not merely that the driver was capable of moving it or intended to. That single requirement is the foundation of the entire defense.
Why officers so often miss the driving
A great many DUI arrests happen after the driving is over. Police arrive at the scene of a single-car accident with no witnesses. They find someone pulled over on the shoulder. They respond to a parking lot, a driveway, or a report of a person asleep behind the wheel. In all of these situations the officer never personally observed the car in motion. That gap matters, because the officer's first-hand observation of driving is usually the strongest proof the state has, and without it the prosecution has to stitch the element together from circumstantial pieces.
When the defense comes up
It comes up most often when someone is found parked or asleep in a parked car, or after an accident that no officer witnessed. If the only proof that you were driving is circumstantial, an admission, the warmth of the hood, your position in the car, the keys in the ignition, the prosecution's case can be far weaker than it first appears. Each of those clues has innocent explanations: a person can sit in a warm car without having just driven it, can move to the driver's seat for warmth, or can have pulled over responsibly and stopped driving precisely because they knew they should not continue.
The danger of admissions
In the absence of an eyewitness, the case often rises or falls on what you said. "I only drove a little way," or "I was just heading home," can hand the prosecution the very element it could not otherwise prove. This is one of the clearest illustrations of why it is so important not to volunteer information at a stop. When an admission is the only evidence of driving, I examine closely how it was obtained, whether it was accurate, whether Miranda applied, and whether it can be challenged or excluded. The corpus delicti rule also matters here: a conviction generally cannot rest on your statement alone without some independent evidence that the crime occurred.
The accident with no witness
Single-vehicle accidents are a common setting for this defense. The officer arrives to find a car off the road and a driver nearby, but no one saw the crash or who was at the wheel, and critically, no one can establish when the driving happened. If there is any meaningful gap between the driving and the chemical test, the rising or falling BAC over that interval can mean the state cannot prove your blood alcohol while you were actually driving, which ties the no-driving issue to the rising BAC defense.
Pulling over is not a confession
I often see cases where the client did the responsible thing. They realized they should not be driving, so they pulled into a lot or onto the shoulder, turned off the engine, and waited it out or fell asleep. Then an officer found them and arrested them for DUI. The frustrating irony is that the safe choice becomes the basis for the charge. But these are frequently the most defensible cases, because if the prosecution cannot prove when, or whether, the car moved while the person was over the limit, the driving element is genuinely in doubt. Deciding not to drive should not be treated as the crime of driving.
Keys, ignition, and "control" myths
People often believe that simply having the keys, or sitting in the driver's seat, or having the engine running for heat, is automatically a DUI. In California, that is not the law. Unlike some states that criminalize being in "actual physical control" of a vehicle, California generally requires proof of actual movement. So the keys in the ignition and the engine idling for warmth, without evidence the car was driven, do not by themselves establish the driving element. This is a crucial distinction that even some officers get wrong at the scene.
How I attack it
I scrutinize who actually saw the car move, the reliability of any statements you made, and whether the circumstantial evidence really proves driving beyond a reasonable doubt. I pull the dispatch records and any witness accounts, pin down the timeline, and test whether the officer simply assumed driving rather than proving it. If the element is not solidly established, the charge is vulnerable to reduction or dismissal, and it is also a powerful issue at the DMV hearing, where the question of driving must also be addressed. Even when the driving cannot be entirely defeated, raising serious doubt about it gives me real leverage to negotiate the charge down to a wet reckless or to push for a dismissal of the most serious counts.
