Mr. Haynes Explains: Can I Get a DUI in Tennessee If I Was Parked or Asleep in My Car?

Yes.

In Tennessee, you do not have to be driving down the road to be charged with DUI. The statute does not only punish “driving.” The actual language is that a person may not “drive or be in physical control” of a motor vehicle while under the influence, with a blood alcohol concentration of .08% or more, or with a .04% BAC or more in a commercial motor vehicle. That law applies not only on public roads, but also on streets, alleys, shopping centers, trailer parks, apartment complexes, and other places generally frequented by the public.

That means a DUI can happen in a gas station parking lot, a grocery store parking lot, an apartment complex, or on the side of the road. The car does not necessarily have to be moving.

The Big Question: Were You in “Physical Control” of the Vehicle?

The phrase to focus on is physical control.

People often ask this question like this:

“Can I get a DUI if I was not actually driving?”

The answer is: maybe. It depends on the facts.

The leading Tennessee case is State v. Lawrence. In that case, the defendant was found asleep in his truck. The truck was parked completely in a public road. The motor was off. The defendant was alone. The keys were in his pocket. The Tennessee Supreme Court upheld the DUI conviction and said Tennessee courts should look at the totality of the circumstances to decide whether a person was in physical control of the vehicle.

The Court listed several factors that matter:

• Where the person was located in relation to the vehicle;
• Where the ignition key was located;
• Whether the motor was running;
• Whether the person, but for being intoxicated, had the ability to direct the use or non-use of the vehicle; and
• Whether the vehicle was capable of being operated or moved.

So the question is not simply, “Was the car moving?” The question is whether the State can prove that the person had enough control over the vehicle to count as being in physical control.

These Cases Used to Turn Heavily on “Where Are the Keys?”

For years, one of the biggest questions in these parked-car DUI cases was simple:

“Where were the keys?”

Keys in the ignition? Bad fact.

Keys in your pocket while you are sitting behind the wheel? Also a bad fact.

Keys on the passenger seat? Still potentially a bad fact.

Keys in the trunk? Safer bet.

But “safer bet” does not mean “guaranteed safe.” Tennessee uses a totality-of-the-circumstances test. The key location matters, but it is not the only thing that matters. The court can also look at whether you were in the driver’s seat, whether the vehicle was operable, whether the engine was running, where the car was parked, whether the car was blocking traffic, whether anyone saw you drive, and whether there is circumstantial evidence that you had driven there while impaired.

The Tennessee Supreme Court in Lawrence specifically rejected an overly technical rule where the case turns only on whether the defendant had the key in a certain place. The Court said the total circumstances matter, not just one fact.

Push-to-Start Cars Make This Problem Worse

Modern cars have made this issue more complicated.

In older vehicles, putting the keys in the trunk might have been a much stronger fact for the defense. If the keys were not in the ignition, not in your pocket, and not within easy reach, then the State had a harder time arguing that you could immediately start the car and drive away.

But many newer vehicles have push-to-start systems. With those vehicles, the key fob does not have to be in the ignition because there is no ignition key in the old-fashioned sense. Depending on the vehicle, the car may start if the fob is close enough.

That means “I threw the keys in the trunk” may not help as much if the car can still be started with the push of a button.

The better question is not just “Where were the keys?” The better question is:

Could the person realistically start, move, or direct the use of the vehicle?

That is why these cases are so fact-specific.

A Recent Tennessee Case Shows Why the Key Issue Still Matters

In State v. Joshua Morris, decided by the Tennessee Court of Criminal Appeals in 2026, the defendant was found asleep in the driver’s seat of a vehicle parked in front of a convenience store. The engine was not running. Officers saw keys on the passenger seat, but there was an issue over whether the officers had confirmed that those keys actually belonged to that vehicle.

The case had a complicated procedural history involving implied consent and collateral estoppel, so it was not a clean “not guilty because the keys were not proven” decision. In fact, the Court of Criminal Appeals reversed the dismissal of the DUI indictment and sent the case back for further proceedings.

But the case is still useful because it shows that these details matter. If the State cannot prove the keys belonged to the vehicle, or cannot prove the vehicle could be started or moved, that may become an important defense issue.

Sleeping It Off in the Driver’s Seat Is Risky

A lot of people think they are doing the responsible thing by deciding not to drive and sleeping in their car.

Morally, that may be better than driving drunk.

Legally, it can still create a DUI problem.

If you are drunk, sitting in the driver’s seat, with access to the keys, in a vehicle that can be driven, the State may argue that you were in physical control of the vehicle. That is true even if the engine was off. That is true even if the car was parked.

The safer choice is to not get behind the wheel at all. Call someone. Use a rideshare. Sleep somewhere else. Have a sober person take the keys. Do not sit in the driver’s seat with the ability to start the vehicle.

What About Police Walking Up to a Parked Car?

Another major issue in parked-car DUI cases is whether the officer had the right to walk up, make contact, block the vehicle, order the person out, or continue detaining the person.

This is where the community caretaking exception comes in.

Police officers are not only criminal investigators. They also check on people who may be hurt, unconscious, passed out, stranded, or creating a safety hazard. Tennessee recognizes that an officer may sometimes approach or seize a vehicle under the community caretaking exception, even without ordinary reasonable suspicion of a crime.

The leading Tennessee case is State v. McCormick. In that case, the Tennessee Supreme Court held that the community caretaking doctrine can justify a warrantless seizure of a vehicle if the State proves two things:

First, the officer had specific and articulable facts that objectively showed a community caretaking action was needed, such as a person needing help or a public safety threat.

Second, the officer’s actions and the scope of the intrusion were reasonably restrained and tailored to that caretaking need.

In McCormick, the officer found a vehicle around 2:45 a.m. partially in the roadway, blocking much of a grocery store entrance. The engine was running. The lights were on. The defendant was slumped over the steering wheel. The Tennessee Supreme Court held that the officer’s welfare check was valid under the community caretaking exception. Once the officer smelled alcohol and saw an open beer bottle, the case moved from welfare check to DUI investigation.

The Community Caretaking Exception Has Limits

The community caretaking exception is not a magic wand. Police do not get unlimited authority just because they say, “I was checking on someone.”

The State still needs facts. Real facts. Specific facts. Not just a hunch.

A recent Tennessee case, State v. Jansen L. Smith, shows the limitation. In that case, officers were dealing with a report involving a disturbance and possible concern for a female passenger. The Court of Criminal Appeals held that the later detention went too far. The court emphasized that government intrusions must be based on particularized facts, not general assumptions. The court reversed the DUI conviction, vacated it, and dismissed the charge because the detention exceeded the proper scope and duration of the stop.

That case matters because it shows the line between a legitimate safety check and an unlawful detention.

An officer may be allowed to check on someone.

But once the welfare concern is resolved, the officer cannot simply keep fishing unless new facts create reasonable suspicion or probable cause.

Federal Courts Have Also Put Limits on Community Caretaking

Federal law matters too because DUI stops and seizures involve the Fourth Amendment.

In Caniglia v. Strom, the United States Supreme Court made clear that community caretaking is not an open-ended license for police to search or seize anywhere they want. The Court held that the community caretaking doctrine does not justify warrantless searches and seizures in a home the same way it may apply in the vehicle context. Vehicles and homes are treated differently under the Fourth Amendment.

The Sixth Circuit, which covers Tennessee, has also limited the doctrine. In Taylor v. City of Saginaw, the Sixth Circuit said the community caretaking exception applies only in narrow situations involving public safety, and it does not give the government refuge from the warrant requirement unless delay is reasonably likely to result in injury or ongoing harm to the community.

In Clemons v. Couch, the Sixth Circuit applied Caniglia and held that an officer could not justify a warrantless home entry by relying on the community caretaker exception. The court also repeated that, even where the doctrine might apply, there must be a real concern that delay would likely cause injury or ongoing harm.

For parked-car DUI cases, the takeaway is this: community caretaking is still alive in the vehicle context, but it has limits. The officer’s actions must match the safety concern. If the officer goes beyond that without reasonable suspicion or probable cause, there may be a suppression issue.

So Can You Get a DUI While Parked or Asleep?

Yes.

You can be charged with DUI in Tennessee even if the officer never saw the car moving.

But these cases are often defensible because they turn on details:

• Where were you sitting?
• Where were the keys?
• Was the engine running?
• Was the vehicle operable?
• Could the car start with a push button?
• Were you on a public road or in a public parking lot?
• Did anyone see you drive?
• Was the officer’s initial contact legal?
• Did the welfare check turn into an unlawful detention?
• Did the officer have reasonable suspicion or probable cause?

The answer depends on the facts.

If you were charged with DUI after being found parked, asleep, or passed out in a vehicle, the case needs to be reviewed carefully. These are not always straightforward DUI cases. Sometimes the fight is over physical control. Sometimes the fight is over whether the officer had the right to detain you. Sometimes the fight is over whether the State can prove the vehicle could actually be started or moved.

A parked-car DUI is still a DUI. But it may also have defenses that do not exist in a normal traffic-stop DUI case.
