A driving under the influence (DUI) charge in South Carolina generally means law enforcement believes you operated (or were in actual physical control of) a motor vehicle while alcohol, drugs, or a combination of substances materially and appreciably impaired your faculties to operate the motor vehicle. DUI cases move on two tracks at the same time: (1) the prosecution in criminal court (guilt/innocence and criminal penalties) and (2) Administrative consequences related to the Department of Motor Vehicles and the Office of Motor Vehicle Hearings affecting the status of your driver’s license.
What Counts as a DUI in South Carolina
Impairment-based DUI
South Carolina DUI law focuses on whether alcohol and/or drugs impaired your ability to drive to a meaningful degree, not just whether you have been drinking. The State typically tries to prove impairment using driving behavior, field sobriety tests, officer observations, and (when obtained) breath or blood testing.
Is there a legal limit in South Carolina?
From a technical standpoint, there is no legal limit in South Carolina. In other words, there is not an amount of alcohol in your system that automatically convicts you of DUI. However, there are inferences to be made based upon the alcohol believed to be in your system.
S.C. Code Ann. § 56-5-2950 provides that if alcohol concentration is 0.05 or less, “it is conclusively presumed that the person was not under the influence of alcohol;” if alcohol concentration is greater than 0.05 but less than 0.08, “this fact does not give rise to any inference that the person was or was not under the influence of alcohol;” and that if alcohol concentration was 0.08 or more, “it may be inferred that the person was under the influence of alcohol.”
Notwithstanding, remember that State does have to prove that you were under the influence of alcohol, but rather that your faculties to operate a motor vehicle were materially and appreciably impaired.
“Actual physical control” (not just driving)
You do not always have to be seen driving down the road to be charged. A person can be charged if the State claims they were in actual physical control of a vehicle while impaired—often argued in situations involving a parked car, sleeping in the driver’s seat, or having access to the keys.
Implied Consent: Breath/Blood Testing and Refusal
South Carolina’s implied consent laws mean that by driving in the state, you are deemed to have consented to chemical testing (typically breath, sometimes blood/urine depending on circumstances) after a lawful DUI arrest.
If you refuse a requested test, the DMV may impose an administrative suspension based on the refusal, separate from what happens in the criminal case. However, a driver who refuses breath testing and subsequently has his or her license administratively suspended can appeal the suspension within thirty (30) days of receipt of the Notice of Suspension. During the pendency of the appeal, the suspended driver may apply for and receive a temporary driver’s license from the DMV.
Refusal issues are litigated in an administrative hearing with a narrower set of questions than the criminal trial.
DUI “Levels” in South Carolina
South Carolina law increases DUI penalties based on two main factors: whether it is a first, second, third, or subsequent offense, and the driver’s alleged blood alcohol concentration (“BAC”). In general, the higher the BAC and the more prior DUI convictions a person has, the more severe the penalties become.
For a first-offense DUI in South Carolina, penalties can range from a fine and as little as 48 hours in jail or public service work, all the way up to 90 days in jail for drivers accused of having a BAC of .16% or higher. A first offense with a BAC under .10% carries the lowest penalties. A BAC between .10% and .15% increases the mandatory minimum jail time, and a BAC of .16% or greater carries substantially harsher penalties, including up to 90 days in jail and significantly larger fines.
A second DUI offense carries much more serious consequences. Depending on the alleged BAC level, a person can face mandatory jail time ranging from 5 days to 90 days, with maximum prison exposure of up to 3 years. Fines also increase substantially, with thousands of dollars in potential penalties. South Carolina law also limits how much of the fine can be suspended by the court for second-offense DUI cases.
For a third DUI offense, the penalties become even more severe and can include mandatory jail sentences ranging from 60 days to 6 months, depending on the BAC level. Maximum prison exposure increases to as much as 5 years, and fines can reach up to $10,000 for high-BAC cases.
A fourth or subsequent DUI offense in South Carolina is treated as a felony-level offense and carries mandatory prison time. A person convicted of a fourth DUI can face anywhere from 1 to 7 years in prison depending on the alleged BAC level. Unlike lower-level DUI offenses, these cases carry life-changing consequences and require an aggressive legal defense strategy from the outset.
In addition to the possible jail sentences and fines, upon conviction of DUI in South Carolina, the convicted driver must enroll in and successfully complete an Alcohol and Drug Safety Action Program certified by the Office of Substance Use Services. This can cost up to $2,500 dollars.
Are There Alternatives to Jail Time Upon Conviction?
Yes. In some South Carolina DUI cases, there are alternatives to traditional jail time — particularly for first-offense cases and some lower-level second offenses.
For a first-offense DUI, the law specifically allows a judge to substitute mandatory jail time with public service employment (community service). For example, instead of serving the minimum 48 hours, 72 hours, or even 30 days in jail depending on the alleged BAC level, the court may allow the person to complete the equivalent amount of public service work. However, the judge cannot force someone to choose public service over jail time — it is an option that may be offered.
In many cases, defense attorneys also work to minimize or avoid active jail sentences through negotiated plea agreements, reduced charges, treatment programs, alcohol education courses, or by presenting mitigating factors to the court. Factors like a clean record, cooperation, employment history, military service, family responsibilities, or proactive counseling can sometimes help reduce penalties.
That said, as DUI offenses increase in number or involve higher alleged BAC levels, avoiding jail becomes much more difficult. Second, third, and especially fourth-offense DUIs carry mandatory minimum jail or prison sentences under South Carolina law, and judges have far less flexibility to suspend those sentences entirely. However, the judge may provide for the sentence to be served upon terms and conditions as he considers proper including, but not limited to, weekend service or nighttime service in any fashion he considers necessary. In some cases, a skilled lawyer can secure home confinement for the duration of the mandatory sentence.
Common Client Questions About DUIs in South Carolina
What is the penalty for a DUI in South Carolina?

Can you get a DUI on a bicycle in South Carolina?

Practical Takeaways
