South Carolina DUI Laws and Penalties: What You Need to Know
Last Updated on January 12, 2026
The moment you see flashing blue lights in your rearview mirror, everything changes. Within minutes, you’re facing questions about drinking, field tests on the side of the road, and paperwork full of terms that carry lifelong consequences.
South Carolina doesn’t treat impaired driving lightly. Even a first arrest can mean jail time, thousands in fines, and license restrictions that affect your job, your family, and your future. In fact, SCDPS reported over 16,000 DUI arrests in South Carolinalast year, showing how common these cases are and how seriously the state enforces its laws.
At theLaw Offices of Lori S. Murray, we’ve seen firsthand how confusing South Carolina DUI laws can feel when you’re in the middle of a case. Knowing the statutes isn’t just about understanding the BAC limit, it’s about knowing what happens after an arrest, what penalties really look like in practice, and how recent law changes reshape your options.
This article walks you through the statutes, the penalties for first-time and repeat offenders, what refusal means under implied consent, when DUI becomes a felony, and how these cases impact daily life.
What Do South Carolina DUI Laws Say?
Under SC Code §56-5-2930, DUI is defined as operating a vehicle while under the influence of alcohol, drugs, or any intoxicant “to the extent that the person’s faculties to drive a motor vehicle are materially and appreciably impaired.” This doesn’t require you to be fully intoxicated, impairment that affects safe driving is enough for a charge.
South Carolina applies strict limits:
- For drivers 21 and older, the legal BAC is .08% or higher.
- For commercial drivers, the limit is .04%.
- For drivers under 21, the standard is even lower: .02% or more can lead to a license suspension under the state’s zero-tolerance policy.
Separate from DUI, the state also recognizes Driving with an Unlawful Alcohol Concentration (DUAC) under §56-5-2933, which focuses only on BAC levels at or above .08, regardless of visible impairment. Both laws are prosecuted aggressively, and either can affect your record for years.
SC DUI Laws and Penalties for First, Second, and Third Offenses
The punishment for DUI in South Carolina is shaped by both your BAC and your prior record. Under §56-5-2940, penalties escalate with every conviction, and the 2024 “All Offender Law” now requires ignition interlock devices for every conviction, even first offenses.
First Offense DUI South Carolina
For a first offense, the law sets a range of 48 hours to 30 days in jail and fines starting around $400. If your BAC was under .10, penalties may be lighter; if it was .16 or higher, expect the upper end of sentencing and mandatory interlock installation. Your license will be suspended for six months, and you’ll have to complete the Alcohol and Drug Safety Action Program (ADSAP) before reinstatement.
Second Offense DUI South Carolina
A second offense raises the stakes: fines rise into the thousands, jail can run from 5 days to a year, and your license is suspended for two years. At this point, an ignition interlock device isn’t optional, it’s mandatory before you can get back on the road.
Third / Repeated Offense DUI South Carolina
By the third offense, the consequences become life-altering. Jail time can reach 3 years, fines top $10,000, and your license can be revoked permanently if the offense falls within ten years of your first. Judges and prosecutors view third-time offenders as repeat risks, and sentences reflect that.
These numbers are more than lines in the statute. They determine whether you can keep your job, whether you need to arrange rides for your children, and whether your professional license survives after court.
Felony DUI Charges Under South Carolina Law
While most DUIs are misdemeanors, South Carolina law turns them into felonies when an accident leads to great bodily injury or death. Under §56-5-2945, the penalties are severe:
- If another person suffers great bodily injury, the sentence is 30 days to 15 years in prison, plus fines between $5,000 and $10,000.
- If someone dies, the range becomes 1 to 25 years in prison, with fines up to $25,000.
The statute defines “great bodily injury” as any injury creating a substantial risk of death, serious permanent disfigurement, or protracted loss of a bodily function. This means even a single crash caused while impaired can transform a first-time misdemeanor into a felony carrying decades in prison.
Implied Consent and Refusing a Breathalyzer in SC
Many people assume refusing a breath test is the safe move. South Carolina’s implied consent law (§56-5-2950and§56-5-2951) says otherwise. By driving in the state, you’ve agreed to submit to chemical testing if lawfully arrested. Refusal triggers its own punishments:
- A first refusal leads to a 6-month license suspension.
- A sample showing .15 or higher BAC results in at least a 1-month suspension, even without a conviction.
- You have 30 days to request a hearing with the Office of Motor Vehicle Hearings (OMVH) to challenge the suspension.
During that time, you may qualify for a Temporary Alcohol License, allowing limited driving. If you lose the hearing, you’ll face longer suspension but may opt into the ignition interlock program, where each month counts as credit toward your suspension.
Refusal isn’t a free pass. Under SC DUI Laws and penalties, saying no to a breath test brings its own six-month license suspension for a first refusal and can be used by prosecutors as evidence that you were impaired. On the other hand, taking the test could produce results that limit your defense options later.
Because both choices carry consequences, the safest step is to speak with a defense attorney before deciding how to respond. At the Law Office of Lori S. Murray, our DUI attorney, walks you through these decisions so you understand exactly what’s at stake in that moment.
What Happens During a DUI Arrest in South Carolina
Here’s how a DUI case usually unfolds. You’re stopped for suspicion, maybe weaving, maybe a broken taillight. The officer approaches, smells alcohol, and asks questions about where you’ve been. You’re asked to step out of the vehicle and complete field sobriety tests.
If the officer believes you’re impaired, you’re arrested and taken to a breath testing site. Under§56-5-2953, South Carolina requires video recording of the traffic stop and the breath test procedure. This footage becomes evidence for both sides. If the breath test shows impairment or you refuse, you’ll be booked, processed, and given paperwork listing your charges, license suspension details, and court date.
It’s intimidating, and for many, it’s their first time in handcuffs. But every step has rules, and mistakes by officers can affect the outcome later.
Defenses Against DUI Charges in South Carolina
No two DUI cases are alike, and neither are the defenses. Some focus on whether the stop itself was legal, without probable cause, the case may collapse. Others center on the testing process: Breathalyzers must be properly calibrated, and medical conditions can mimic impairment symptoms.
The video required under South Carolina DUI laws can also expose officer errors in field sobriety tests or Miranda warnings. In some cases, negotiations with the Solicitor’s Office may reduce a DUI to reckless driving, which can spare your record from long-term damage.
While defenses vary, the takeaway is clear: DUI charges are not unbeatable, but they require detailed review and quick action. Speaking to your DUI lawyer as soon as possible is critical.
Long-Term Consequences Beyond DUI Penalties
South Carolina DUI penalties extend far past fines and jail. Insurance premiums rise sharply after a conviction, sometimes doubling or tripling. Employers in fields like healthcare, trucking, or education may terminate contracts or deny promotions. Professional licensing boards can impose sanctions.
Travel can even be restricted, some countries, like Canada, deny entry to travelers with DUI convictions. For parents, the stigma can affect custody negotiations. For young people, it can derail college or career plans.
These are the parts of SC DUI laws you won’t see in the statute books but feel just as heavily.
FAQs About SC DUI Laws and Penalties
Can a DUI be expunged in South Carolina?
No. Under §56-5-2930, a DUI conviction cannot ever be erased from your criminal record. If the charge is reduced to something else like reckless driving and later dismissed, that different charge may qualify for expungement. But once a DUI conviction is entered, it is permanent. That’s why the outcome of your case before conviction is so important.
How long does a DUI stay on your record in SC?
On your criminal record, a DUI is permanent. For driver’s license purposes, the DMV counts a DUI for 10 years when deciding suspensions or repeat penalties. This “lookback” period means even one conviction can raise your insurance costs and affect license eligibility for a decade, while employers and schools can still see the criminal record long after that.
Can I get a hardship license after a DUI in SC?
Since May 2024, South Carolina changed its rules with the “All-Offender Law.” The old provisional license for a first DUI is gone. Instead, many drivers now have to enter the ignition interlock program to keep driving. You may qualify for a Temporary Alcohol License (TAL) right after arrest, and later drive with an interlock device while your case or suspension plays out. It’s stricter, but it gives you a way to stay on the road legally.
