A first-offense DUI in South Carolina is a misdemeanor under S.C. Code § 56-5-2930. The penalty depends on your breath or blood result: a $400 fine or 48 hours to 30 days in jail below 0.10; $500 or 72 hours to 30 days from 0.10 to 0.15; and $1,000 or 30 to 90 days at 0.16 and above. A conviction also brings a six-month license suspension, the ADSAP program and, since May 19, 2024, an ignition interlock device for six months for every first offender. DUI cannot be expunged and is not eligible for pretrial intervention. The license side of the case has its own 30-day deadline.
DUI and DUAC: what the State has to prove
DUI (S.C. Code § 56-5-2930) requires proof that your faculties to drive were “materially and appreciably impaired” by alcohol, drugs or both. DUAC (§ 56-5-2933) is the per-se offense: a breath or blood alcohol concentration of 0.08 or more measured within two hours of arrest, with no need to prove impairment. The penalties are identical, the State chooses which charge to pursue, and you cannot be convicted of both for one stop. Jack Frost made these arrests for fourteen years and now prosecutes them for the Town of Summerville, so he knows what the officer must document and where the documentation usually fails.
First-offense penalties under § 56-5-2930
| Breath or blood result | Fine | Jail, or public service in place of the minimum |
|---|---|---|
| Under 0.10 | $400 | 48 hours to 30 days |
| 0.10 to 0.15 | $500 | 72 hours to 30 days |
| 0.16 or higher | $1,000 | 30 to 90 days |
The fine cannot be suspended, and with court assessments and surcharges a $400 fine comes to roughly $992 by the time it is paid, according to the Department of Public Safety. The judge may allow public-service hours in place of the minimum jail time but cannot be forced to. Only prior DUI or DUAC offenses within the previous ten years count toward a second or third offense. A first offense is tried in magistrate or municipal court, where you have the right to a jury.
Everything else a conviction brings
- A six-month driver's license suspension, separate from any administrative suspension for a refusal or a high reading.
- ADSAP. Every DUI conviction requires enrollment in the Alcohol and Drug Safety Action Program within 30 days. The statute caps the cost at $500 for education, $2,000 for treatment and $2,500 in total, and the court can hold you in contempt for not enrolling.
- An ignition interlock device for six months. Act 55 of 2023 made South Carolina an all-offender interlock state on May 19, 2024. Under S.C. Code § 56-5-2941 a first offender needs the device for six months to regain driving privileges, a second offender for two years, a third for three years (four if the third offense falls within five years of the first), and a fourth offender for life. You pay a state-approved vendor to install, monitor and remove it, and the device will not start the car at 0.02 or above. Most websites still describe the old rule, under which first offenders below 0.15 avoided the device; that rule is gone.
- Insurance. An SR-22 filing for three years and premiums that commonly double or triple.
- A permanent record. DUI and DUAC are excluded from expungement (S.C. Code § 22-5-910) and from pretrial intervention (§ 17-22-50). There is no waiting period after which it comes off.
- Professional consequences for CDL holders, nurses, teachers, pilots, service members at Joint Base Charleston and anyone who holds a security clearance or a concealed-weapons permit.
The license track: implied consent and the 30-day deadline
If you refused the breath test or registered 0.15 or higher, the officer took your license on the spot under the implied-consent law (S.C. Code §§ 56-5-2950 and 56-5-2951). You have 30 days to request a hearing before the Office of Motor Vehicle Hearings, and a timely request usually comes with a temporary alcohol license that lets you keep driving while you wait. The hearing is often the first chance to question the arresting officer under oath, and what the officer says there is locked in for the criminal case. Miss the deadline and the suspension simply stands. If the suspension later takes effect, the interlock-restricted license is now the route back to lawful driving.
The video rule, and when a case is dismissed
South Carolina's DUI video statute (S.C. Code § 56-5-2953) requires the stop to be recorded from the moment the blue lights come on through the field sobriety tests, the arrest and the reading of your rights, and requires video of the breath-test room showing the twenty-minute observation period and the test itself. The statute allows only four narrow excuses, each of which the officer must support with a sworn affidavit. Under City of Rock Hill v. Suchenski (2007), an inexcusable failure to record the required parts of the stop requires dismissal, and you do not have to prove the missing footage would have helped you. In State v. Taylor (2022) the Supreme Court narrowed one piece of that rule: when only the Miranda warning is missing from the recording, the remedy is suppression of your statements rather than dismissal of the case. Jack reviews every minute of video against the officer's report because he knows exactly what the recording is supposed to show.
Second, third and felony DUI
Penalties climb steeply. A second offense within ten years carries a fine of $2,100 to $5,100 and five days to one year in jail at the lowest reading, rising to $3,500 to $6,500 and 90 days to three years at 0.16 or more, with a two-year interlock period. A third offense starts at $3,800 to $6,300 and 60 days to three years and tops out at $7,500 to $10,000 and six months to five years. A fourth offense is a felony punishable by one to seven years. Felony DUI, charged when a crash causes great bodily injury or death, carries 30 days to 15 years and $5,100 to $10,100 in fines for injury, and one to 25 years and $10,100 to $25,100 for a death. Second and subsequent offenses are heard in General Sessions court.
How these cases are defended
- The stop. Was there a lawful reason to pull you over? A stop without reasonable suspicion suppresses everything after it, including a checkpoint that did not follow the required procedures.
- The field sobriety tests. Were they administered and scored as the officer was trained, on video, on a suitable surface, with your medical conditions and footwear taken into account?
- The breath test. The twenty-minute observation period, the machine's maintenance and calibration records, the operator's certification and the required video of the test room.
- Blood draws. The warrant, the chain of custody and the lab's procedures.
- The video. What it shows, what it does not, and whether the statute's requirements and affidavits were met.
- The paperwork. Implied-consent advisements, the ticket itself and the officer's report, compared line by line to the video.
- The negotiation. Where the evidence has problems, a reduction to reckless driving or another non-DUI resolution avoids the interlock, ADSAP and the permanent record. No lawyer can promise one; the facts and the video decide.
Court, and one case we cannot take
First-offense DUI charges from Dorchester or Berkeley County sheriff's deputies and the Highway Patrol are tried in the county magistrate's court, and charges from a town police department in that town's municipal court, with a right to a jury trial in each. Higher offenses go to General Sessions. One exception: Jack serves as the Town of Summerville's DUI prosecutor, so the firm does not defend DUI charges brought by the Summerville Police Department in Summerville Municipal Court. If that is your case, call anyway and we will refer you to a defense attorney we trust.
Frost first: if you have not yet requested the administrative hearing, that is the first call. The criminal case can wait a day; the license deadline cannot.

Questions people ask
What is the penalty for a first-offense DUI in South Carolina?
A fine of $400 to $1,000 or 48 hours to 90 days in jail depending on the breath result, a six-month license suspension, the ADSAP program and, since May 2024, an ignition interlock device for six months. With assessments the $400 fine is close to $1,000.
Do I need an ignition interlock for a first DUI in South Carolina?
Yes. Since May 19, 2024, South Carolina requires the device for nearly every DUI or DUAC conviction, including a first offense with a reading under 0.15. The first-offense period is six months, and you pay the vendor's installation and monthly fees.
Will I lose my license after a first DUI?
A conviction brings a six-month suspension. A refusal or a reading of 0.15 or higher triggers a separate administrative suspension the night of the arrest, which you can contest within 30 days.
Can a first-offense DUI be reduced to reckless driving?
Sometimes, particularly when the video, the stop or the breath test has problems. Reckless driving carries six points and a fine but none of the DUI consequences. Whether a reduction is realistic depends on the evidence, and no lawyer can promise one.
Can a DUI be expunged in South Carolina?
No. DUI and DUAC convictions are excluded from expungement, which is one reason the defense matters so much.
Do I have to take the breath test?
You can refuse, but refusal triggers an administrative suspension and can be used at trial. Whether it helped or hurt depends on facts we will review with you.
How long does a first-offense DUI case take in Dorchester County?
Most magistrate and municipal court cases resolve within three to six months; a jury trial can take longer. The license hearing runs on its own schedule.
