South Carolina treats driving under the influence as a serious crime, and the penalties get heavier with every previous conviction. A first offense can mean jail time, a suspended license, and monetary fines. A DUI causing bodily injury or death becomes a felony conviction with decades in prison on the table.
Your Blood Alcohol Content and your number of previous convictions drive what happens next. Touma Law Group is a veteran-owned South Carolina criminal defense firm, and our experienced defense attorneys include former state prosecutors who once handled DUI cases from the other side of the courtroom.
What a DUI Conviction Actually Costs You
South Carolina Law Section 56-5-2930 makes it illegal to drive while materially and appreciably impaired by alcohol, drugs, or both. A separate law makes it illegal to drive with an unlawful alcohol content of 0.08 percent or higher, sometimes called DUAC. Both carry the same penalties, and both get steeper with each previous offense counted within South Carolina’s ten-year lookback period.
- First offense: for a first-time DUI, a $400 fine (near $992 with assessments and surcharges) or 48 hours to 30 days in jail under a 0.10 percent BAC; a $500 fine or 72 hours to 30 days at 0.10 to 0.159 percent; a $1,000 fine or 30 to 90 days at 0.16 percent or higher. Courts can allow community service in place of the jail minimum. Every tier carries a six-month license suspension.
- Second offense: $2,100 to $5,100 and five days to one year in jail, plus a one-year license suspension.
- Third offense: $3,800 to $6,300 and 60 days to three years in jail, plus a two-year suspension (four years if within five years of the first offense). The motor vehicles can be confiscated if the offense falls within ten years of the first.
- Fourth or subsequent offense: a felony charge carrying one to five years of incarceration and permanent license revocation.
Judges generally cannot suspend the mandatory minimum jail time on a third or later offense, so jail time becomes unavoidable at that point. The legal BAC limit for most adult drivers is 0.08 percent. South Carolina applies a zero tolerance standard to intoxicated drivers under 21, so a BAC of just 0.02 percent can trigger a mandatory license suspension, and commercial drivers face a lower threshold of 0.04 percent whether they were driving a commercial vehicle or their own car.

Why Your License is at Risk Before You Ever See a Judge
A DUI arrest triggers two legal processes from a single charge: the criminal justice system in court, and an administrative license action through the DMV. South Carolina’s implied consent law says anyone who drives on state roads has already agreed to a breath, blood, or chemical test once a law enforcement officer has probable cause for DUI.
If you refuse that test, the DMV can suspend your license even if the DUI charge is later reduced or dismissed. A result of 0.15 percent or higher triggers its own separate suspension. Either can end early through the Ignition Interlock Device Program, and you can request a Temporary Alcohol License or a hearing within 30 days of the notice.
When a DUI Becomes a Felony DUI
South Carolina DUI laws treat a DUI differently once it causes serious bodily harm. Causing great bodily injury brings a mandatory fine of $5,100 to $10,100 and prison sentences between 30 days and 15 years. A death raises the fine to $10,100 to $25,100 and the term to one to 25 years. Courts cannot suspend any part of these mandatory sentences.
“Great bodily injury” means an injury creating a substantial risk of death or causing serious, permanent disfigurement or loss of a bodily function. Single-vehicle crashes and other alcohol-related crashes are common ways these felony charges arise.

The Consequences That Outlast the Courtroom
A DUI conviction does not stop at the fine and jail sentence. Every conviction, including a first offense, requires enrollment in South Carolina’s Alcohol and Drug Safety Action Program before your driver’s license can be reinstated. Insurance carriers typically raise rates once a DUI shows up on your record, and many drivers need SR-22 proof of financial responsibility for years afterward.
Nurses, teachers, and other license holders may also face separate review by their professional licensing boards, and commercial drivers face their own disqualification periods on top of any court penalty.
How Officers Build a DUI Case Against You
Most DUI stops start with an ordinary reason: a broken taillight, a lane violation, or a single-vehicle crash. The police officer then documents signs of impairment, asks for field sobriety tests, and requests a breath or blood test under the implied consent law. South Carolina also runs public safety checkpoints that check for license, registration, and signs of drunk driving.
None of this automatically proves guilt. Field sobriety tests can be affected by fatigue and uneven pavement, and chemical tests depend on equipment that must be calibrated correctly. The right defense depends on the evidence, the charge, and the court handling the case.

No. A charge is not a conviction. The prosecution still has to prove impairment or an unlawful alcohol concentration, and the stop, field sobriety tests, and chemical test results can all be challenged.
South Carolina generally counts DUI and DUAC convictions within a ten-year look-back period. Some felony DUI thresholds may look back further, so an attorney should confirm how your record is being counted.
Often, yes. Many drivers can request a Temporary Alcohol License or enroll in the Ignition Interlock Devices Program to keep driving while the case moves forward, but the deadlines are short.
It can. Some professional licensing boards review criminal charges separately from the court case, and commercial drivers face additional disqualification rules through the DMV.
