Many people believe that if they have had too much to drink, the responsible choice is to pull over, park, and sleep it off. In many situations, that is far better than driving. But our Charleston DUI defense lawyers regularly hear from people who were arrested for a parked car DUI, either while their car was parked or while they were asleep behind the wheel. In this article, we explain how South Carolina defines driving, the evidence prosecutors use to prove it, and why timing is often the key issue in a parked car DUI case. So can you be charged with DUI in South Carolina if you were parked or sleeping in your car and not actually driving?

Quick Answer: Yes, you can be arrested and charged, but sitting or sleeping in a parked car is not, by itself, DUI in South Carolina. S.C. Code Section 56-5-2930 makes it unlawful to drive a motor vehicle while under the influence, and South Carolina does not have an “actual physical control” law for DUI. Under State v. Graves, the State must prove beyond a reasonable doubt that you moved the vehicle and that you were materially and appreciably impaired when you did. A running engine, lights, or keys in the ignition are not enough on their own, but the State can prove driving through circumstantial evidence, such as a warm engine, where the car was stopped, witnesses, video, or your own statements corroborated by independent evidence.

Can You Get a DUI While Parked in South Carolina?

You can be arrested and charged, but sitting or sleeping in a parked car is not, by itself, a crime under South Carolina’s DUI law. Unlike many states, South Carolina does not make it illegal under its DUI statute to be in “actual physical control” of a vehicle while impaired. Our DUI statute makes it unlawful to drive a motor vehicle while under the influence. That means an officer finding you asleep in the driver’s seat is not enough on its own. The prosecution must prove, beyond a reasonable doubt, that you drove the vehicle while you were impaired.

What Does “Drive” Mean Under South Carolina DUI Law?

South Carolina Code Section 56-5-2930 makes it unlawful for a person “to drive a motor vehicle within this State” while under the influence of alcohol, drugs, or both, to the extent that the person’s faculties to drive are materially and appreciably impaired. The offense of driving with an unlawful alcohol concentration (DUAC) under Section 56-5-2933 uses the same language. It prohibits driving while your alcohol concentration is 0.08% or more.

The South Carolina Supreme Court interpreted the word “drive” in State v. Graves, 269 S.C. 356, 237 S.E.2d 584 (1977). In that case, a highway patrolman found the defendant at about 5:00 a.m. slumped over the steering wheel, asleep, with the engine running and the car in gear. When the officer told him to get out, the car rolled forward and had to be stopped. The defendant smelled of alcohol and appeared impaired, but no one saw him driving, and there was no direct or circumstantial evidence that he had put the car in motion while impaired. The Supreme Court affirmed the reversal of his DUI conviction. The Court explained that “driving” is narrower than “operating,” and that a person must have moved the vehicle to be guilty of driving under the influence. The Court also held that the brief movement that happened when the defendant followed the officer’s instructions was not the kind of driving the statute prohibits.

Graves remains important on this issue. Having the engine running, the lights on, or the keys in the ignition is not, by itself, driving. The question is whether the vehicle was in motion under your control while you were impaired. The State may prove that through circumstantial evidence, even if no one saw the vehicle move.

How Can the State Prove You Were Driving?

The fact that no officer saw your car moving does not end the case. South Carolina courts allow the State to prove driving through circumstantial evidence. In parked car cases, prosecutors commonly rely on evidence such as:

  • You were the only person in or near the vehicle, and you were in the driver’s seat;
  • The keys were in the ignition or in your pocket;
  • The hood or engine was warm, suggesting the car had recently been driven;
  • The car was stopped in a place where no one would ordinarily park, such as a travel lane, an intersection, the shoulder of an interstate, or a drive-through lane;
  • The car had recent damage, or there was evidence of a wreck nearby;
  • A witness called 911 after seeing the car being driven erratically;
  • Security video or dash camera footage showing the car arriving where it was found; and
  • Statements you made to the officer or to others about driving.

The strength of this evidence varies greatly from case to case. A car found in the middle of a road with its engine running tells a very different story than a car parked in a legal space outside your own home or a bar, with the engine off and you asleep in the back seat. A statement admitting that you drove can be considered with independent evidence that corroborates it; the State need not have an eyewitness to your driving.

The following table summarizes common evidence in parked car DUI cases and how the defense may respond to it:

Evidence How Prosecutors Use It Possible Defense Response
You were in the driver’s seat Argues that you were the person who drove the car Sitting in the driver’s seat does not prove the car moved, or that you were the one who moved it
Engine running or keys in the ignition Argues that the car had just been driven Under Graves, a running engine is not driving; people often run the engine for heat or air conditioning while parked
Warm hood or engine Argues that the car was driven recently An engine left running while parked stays warm, so a warm hood may not show when the car last moved
Where the car was stopped A car in a travel lane, intersection, or drive-through lane suggests it was driven there A car in a legal parking space, driveway, or lot where you intended to stay tells a different story
Damage or a nearby wreck Argues that the car was driven and involved in a collision The damage may be old or unrelated to the night of the arrest
911 call or video May show the car being driven and when The identity of the driver and the timing of the driving can be challenged
Your statements May supply proof that you drove and when Statements must be corroborated by substantial independent evidence under the corpus delicti rule

Why Does Timing Matter in a Parked Car DUI Case?

Even when the State can show that you drove at some point, it still has to prove that you were impaired at the time you were driving. This is where many parked car cases are won or lost. Consider a few common situations:

  • Drinking after parking. If you drove to a location sober and then drank in your parked car, or went inside a bar or restaurant and later returned to your car to sleep, your impairment at the time the officer found you says little about your condition when you last drove.
  • Unknown time of driving. If there is no evidence showing when the car was parked, the State may not be able to connect your impairment level to the time you were behind the wheel. A car parked for hours with a cold engine is very different from a car with a hot hood.
  • Breath and blood test timing. Under South Carolina’s implied consent statute, Section 56-5-2950, officers must collect a breath sample within two hours of the arrest, and any additional samples within three hours. Those deadlines run from the arrest, not from the last time you drove. If you had been parked for a long time before the officer arrived, a test result may reflect your alcohol concentration long after you drove, rather than your condition while driving.

Evidence about timing can come from receipts, phone records, witnesses, surveillance video, weather conditions, and the officer’s own observations. An experienced DUI lawyer will closely review the timeline, because a gap between driving and arrest can create reasonable doubt.

What About Statements You Make to the Officer?

In many parked car cases, the most damaging evidence is the defendant’s own words. An officer who knocks on your window may ask questions like “Where are you coming from?” or “When did you get here?” An answer like “I just drove from the bar” may help supply proof of driving that the State otherwise could not establish.

South Carolina follows the corpus delicti rule, which means the State cannot convict you based on your statements alone. Substantial independent evidence must corroborate your statements so that, together with those statements, it supports a reasonable belief that the crime occurred. That independent evidence need not, by itself, prove every element of DUI. Courts have considered facts such as being the only person at the vehicle, having the keys, and a warm engine when deciding whether a statement about driving was adequately corroborated. You have the right to remain silent, and you can politely decline to answer questions about when or where you drove until you have spoken with a lawyer.

Does Implied Consent Apply If You Were Parked?

Under Section 56-5-2950, a person who drives a motor vehicle in South Carolina is considered to have consented to chemical testing if arrested for an offense arising out of acts alleged to have been committed while driving under the influence. The South Carolina Supreme Court has held that the arresting officer does not have to actually see the person driving for implied consent to apply. So if you are lawfully arrested for DUI in a parked car, you will likely be asked to submit to a breath test, and refusing can result in an administrative suspension of your license. You can read more about those consequences in our article, What Happens If You Refuse a Breath Test in South Carolina?

You have the right to request a contested case hearing with the Office of Motor Vehicle Hearings within 30 days of receiving the notice of suspension. One issue at that hearing is whether officers lawfully arrested or detained you. When the evidence of driving is weak, that issue can be an important part of challenging the suspension.

Can Police Charge You With Something Else?

If the evidence of driving is weak, officers sometimes charge other offenses. For example, Section 16-17-530 makes it a misdemeanor to be found on a highway or in a public place in a grossly intoxicated condition, commonly called public disorderly conduct or public drunkenness. The penalty is a fine of up to $100 or up to 30 days in jail, and first-time offenders may be eligible for a conditional discharge with the circuit solicitor’s approval. Depending on the facts, prosecutors may also charge an open container violation. These offenses generally carry less serious consequences than a DUI, which can include jail, fines, a license suspension, and participation in the Ignition Interlock Device Program.

The following table compares DUI with other charges that may come up when police find an impaired person in a parked car:

Charge Statute What the State Must Prove Possible Penalty
DUI S.C. Code Section 56-5-2930 You drove a motor vehicle while your faculties to drive were materially and appreciably impaired by alcohol, drugs, or both For a first offense with an alcohol concentration below 0.10%, a $400 fine or 48 hours to 30 days in jail; the court may allow 48 hours of public service instead of the minimum jail term. Assessments and license consequences may also apply; penalties increase with a higher alcohol concentration or prior offenses
DUAC S.C. Code Section 56-5-2933 You drove a motor vehicle with an alcohol concentration of 0.08% or more The same penalty ranges as DUI
Public disorderly conduct S.C. Code Section 16-17-530 You were found on a highway or in a public place in a grossly intoxicated condition A fine of up to $100 or up to 30 days in jail
Open container S.C. Code Sections 61-4-110 and 61-6-4020 You possessed an open container of beer or wine in a motor vehicle on a public highway or highway right-of-way, or transported liquor in a motor vehicle with its cap or seal opened or broken, outside the permitted compartments Generally, a fine of up to $100 or up to 30 days in jail

Can a Parked Car DUI Be Reduced to Reckless Driving?

Sometimes. When the evidence that you drove, or that you were impaired while driving, has real weaknesses, prosecutors may be willing to reduce a DUI to a lesser offense such as reckless driving, or to dismiss the charge. Whether that happens depends on the facts, the strength of the evidence, your prior record, and the practices of the prosecutor handling the case. A reduced charge still has consequences, so it is important to understand the tradeoffs before accepting any offer. We explain those tradeoffs in our article, DUI Versus Reckless Driving in South Carolina: Should You Plead to Reckless?

Does It Matter Where You Sit or Where the Keys Are?

No South Carolina DUI statute says that sitting in the back seat or keeping the keys out of the ignition protects you from a DUI charge. But because the State must prove that you drove while impaired, these facts can matter a great deal. An officer who finds a person asleep in the back seat of a legally parked car, with the engine off and the keys in a pocket, glove box, or trunk, has far less evidence of driving than an officer who finds a person behind the wheel of a running car stopped in a travel lane.

Keep in mind that sleeping in your car does not undo any driving you did before you parked. If you drove to the place where you were found after you had been drinking, the State may still be able to prove DUI through circumstantial evidence and your statements. The safest choice is always to arrange a sober driver, a rideshare, or a taxi before you drink.

What Are the Common Defenses in Parked Car DUI Cases?

Every case depends on its facts, but some of the most common defenses in parked car DUI cases include:

  • No evidence of motion. Under Graves, the State must prove the vehicle was in motion. A running engine or a person asleep behind the wheel is not enough on its own.
  • No evidence of when you drove. If the State cannot show when the driving occurred, it may not be able to prove you were impaired while driving.
  • Uncorroborated statements. Your statements alone cannot support a conviction without substantial independent evidence corroborating them.
  • Problems with the video. Section 56-5-2953 requires video recording at the incident site, including any field sobriety tests and the arrest, and at the breath test site. Missing or incomplete video can be grounds for challenging the charge, although the statute recognizes exceptions and a missing recording does not always require dismissal.
  • Challenges to the stop or arrest. Officers may approach a parked car and speak with its occupants without necessarily detaining them, but any detention must have a lawful basis, and a DUI arrest must be supported by probable cause. If the detention or arrest was unlawful, the court may suppress evidence gathered afterward.

If you are charged with DUI after being found in a parked car, do not assume the case against you is as strong as the officer suggests. You can find answers to other common questions in our DUI FAQs.
