Last reviewed July 2026. This guide covers South Carolina law as it stands in 2026, including the ignition-interlock changes that took effect May 19, 2024. It is general information, not legal advice about your case.

If you were arrested for DUI in Rock Hill or anywhere in York County, the criminal charge is often only half the problem. If you refused the breath test — or took it and registered .15% or higher — a separate administrative suspension hit your license immediately, and you have just 30 days from the arrest to challenge it. That deadline runs whether or not you have a court date. This guide walks through both tracks under current South Carolina law: what the State has to prove, what the penalties actually are at each level, the videotape rule that makes South Carolina DUI defense different from almost every other state, and what happens to your license under the 2024 expansion of Emma’s Law. Where it makes sense to talk through how these rules apply to your own arrest, a Rock Hill DUI lawyer can review your case in a free consultation.

DUI, DUAC, and Felony DUI: Three Different Charges

South Carolina splits impaired driving into three distinct offenses, and which one you’re charged with changes the entire shape of the defense.

DUI — S.C. Code § 56-5-2930

The standard DUI statute makes it unlawful to drive while under the influence of alcohol, drugs, or both, to the extent that your faculties to drive are “materially and appreciably impaired.” That word “materially” matters: the State must prove actual impairment, not just that you had been drinking. A breath test is not strictly required for a DUI conviction — prosecutors can build a case on driving behavior, appearance, and field sobriety tests — but if a test shows .08% or more, the jury may infer impairment from the number.

DUAC — S.C. Code § 56-5-2933

Driving with an Unlawful Alcohol Concentration is South Carolina’s “per se” offense: driving with an alcohol concentration of .08% or higher, full stop. Impairment is irrelevant. You could perform every roadside test flawlessly, and the State can still convict on the number alone — provided the stop was lawful and the test was taken within two hours of arrest. The flip side: because the whole case is the number, a DUAC defense attacks the machine and the testing procedure — calibration records, the required observation period, operator compliance — rather than your roadside behavior. One more rule worth knowing: the State cannot prosecute you for both DUI and DUAC from the same incident. It has to pick one.

Felony DUI — S.C. Code § 56-5-2945

When an impaired-driving incident causes great bodily injury or death, the charge becomes felony DUI. The State must prove three things: impairment, a separate violation of law or neglected legal duty while driving (running a light, crossing the center line), and that this act proximately caused the injury or death. That third element is a genuine battleground — if the crash would have happened regardless of anything the driver did wrong, the causation chain can break, even if the driver was impaired. “Great bodily injury” is itself defined narrowly: injury creating substantial risk of death, serious permanent disfigurement, or protracted loss of a bodily function.

South Carolina DUI Penalties in 2026, by Offense and BAC Tier

Since 2009, South Carolina has scaled DUI sentences on two axes: your prior DUI/DUAC history within the last ten years — convictions, guilty pleas, no-contest pleas, and out-of-state equivalents all count — and your BAC tier — under .10%, .10 to .15%, or .16% and above. If you refused the test, the criminal penalty is generally set at the lowest tier (the refusal has separate license consequences, covered below).

The fines below are base statutory fines. Court assessments and surcharges roughly double them or more in practice — a $400 base fine becomes close to $1,000 out the door.

First offense — heard in magistrate or municipal court

Second offense — General Sessions Court

Third offense — General Sessions Court

For a third offense, judges are statutorily barred from suspending the mandatory minimum jail time.

Fourth or subsequent offense — felony

A fourth DUI or DUAC within ten years is a felony: mandatory imprisonment of 1–5 years (under .10%), 2–6 years (.10–.15%), or 3–7 years (.16%+), and permanent revocation of the driver’s license.

Felony DUI involving injury or death

• Great bodily injury: mandatory fine of $5,100–$10,100 and 30 days to 15 years in prison; license suspended for the imprisonment period plus three years.
• Death: mandatory fine of $10,100–$25,100 and 1 to 25 years in prison; license suspended for the imprisonment period plus five years.

The 30-Day License Clock: Implied Consent, Refusals, and the OMVH Hearing

Under S.C. Code § 56-5-2950, driving in South Carolina means you’ve already consented to a breath, blood, or urine test after a lawful DUI arrest. You keep the right to refuse — officers can’t force a conscious driver to blow without a warrant — but refusal has automatic consequences that arrive long before any trial:

• Refuse the test: immediate administrative suspension — six months for a first refusal, nine months for a second refusal within ten years. The refusal itself can also be used against you as evidence at trial.
• Take the test and register .15% or higher: immediate one-month administrative suspension.

Either way, you have exactly 30 days from the arrest to fight it. Here’s the sequence under current rules:

1. Keep the Notice of Suspension the officer handed you — that physical form is also the hearing-request form.
2. Request a hearing with the S.C. Office of Motor Vehicle Hearings (OMVH) within 30 days, with the mandatory $200 filing fee. A federal court confirmed in White v. Shwedo (2020) that this fee cannot be waived, even for indigency.
3. Get a Temporary Alcohol License (TAL): once the OMVH has received your hearing request, a $100 fee at any DMV office obtains the TAL. It restores full, unrestricted driving — no route or hour limits — while the hearing is pending.

Winning the OMVH hearing ends the administrative suspension — but it is completely separate from the criminal case. You can win at the OMVH and still face the criminal charge, and a later conviction brings its own suspension. The two tracks are independent — the outcome of one does not decide the other — which is why they need to be defended in parallel, not sequentially. The administrative record from a refusal case often shapes the criminal defense too.

The Videotape Rule: South Carolina’s Distinctive Defense Lever

S.C. Code § 56-5-2953 requires nearly every DUI arrest in South Carolina to be recorded on video at two places — and the recording requirements are specific enough that violations are a recurring, litigated defense issue:

• At the incident site: recording must begin no later than the officer activating blue lights, and must capture your conduct before arrest, any field sobriety tests, the arrest itself, and the officer reading you your Miranda rights — on camera.
• At the breath-test site: the entire testing procedure must be recorded, including the mandatory 20-minute observation period before the test, the advisement that you’re being recorded, and your right to refuse.

The observation period is a frequent pressure point. SLED protocol requires the officer to actually watch the subject for those 20 minutes — because belching, vomiting, or anything in the mouth can introduce “mouth alcohol” and artificially inflate the reading. When the required video shows the officer doing paperwork or leaving the room instead, the test result itself becomes vulnerable to a motion to suppress.

The statute has exceptions — an officer can submit a sworn affidavit that the camera was inoperable despite reasonable maintenance, that emergency medical treatment made recording impossible, or that other genuine exigencies applied. But where no valid exception exists, South Carolina appellate courts have taken the requirement seriously:

• City of Rock Hill v. Suchenski (2007) — a case that began right here in Rock Hill — where the Supreme Court held that dismissal was the remedy: it threw out the DUAC charge because the videotaping statute was violated and the State had preserved no statutory exception.
• State v. Gordon (2015) held that an eye-movement (HGN) test isn’t legally “recorded” if the driver’s head isn’t visible on the video.
• State v. Taylor (2022) recalibrated the remedy going forward: for an incident-site Miranda recording violation, courts now suppress the tainted evidence (such as post-arrest statements or subsequent test results) rather than automatically dismissing the whole case.

The practical takeaway: the video record — and any gap in it — is one of the first things worth examining in any York County DUI case. It’s objective, it’s mandatory, and it either supports the officer’s account or it doesn’t.

Your License After a Conviction: ADSAP and the Ignition Interlock (2026 Rules)

This is the area where South Carolina law has changed most recently, and where older information on the internet will steer you wrong.

The old “provisional” and “route-restricted” licenses are gone for new DUI cases. For DUI violations on or after May 19, 2024, Act 55 of 2023 eliminated the traditional hardship-license pathways for DUI and implied-consent suspensions. South Carolina is now an “all-offender” ignition-interlock state: whether the suspension comes from a conviction — including a first offense with a BAC under .15% — or from a sustained implied-consent suspension, the route back to driving runs through ADSAP enrollment and an ignition interlock device (IID).

ADSAP — the Alcohol and Drug Safety Action Program

Every DUI suspension, whether from a conviction or a sustained implied-consent suspension, requires enrollment in ADSAP, the statewide assessment and education/treatment program. Enrollment costs a minimum of $500 and can reach $2,500 if the assessment calls for clinical treatment; county providers offer sliding scales, payment plans, and community-service offsets for those who can’t pay. The deadline has teeth: enrollment is required within 30 days of conviction, and missing it risks a bench warrant and a non-compliance flag on your DMV record.

Emma’s Law after Act 55 — who needs the interlock, and for how long

The device is a breathalyzer wired to the ignition; it blocks the start at a .02% reading and requires rolling re-tests while driving. Violations — failed tests, missed calibrations — add points that extend the IID period. Costs fall on the driver: typically $70–$150 for installation and roughly $60–$130 per month in lease and monitoring fees, plus a $30 monthly state fee. Drivers who genuinely can’t afford it can apply for the state’s interlock indigency fund through the Department of Probation, Parole and Pardon Services, with re-application required every 90 days. Once you enter the IID program, you can’t later swap to simply waiting out a hard suspension — the interlock period must be completed.

Special Situations: Under 21, CDL Holders, Out-of-State Drivers, and Drug DUI

• Drivers under 21 (§ 56-1-286): South Carolina enforces zero tolerance at .02% BAC. A first violation brings a 3-month suspension (6 months with a prior alcohol offense in the past 3 years). If police proceed under the zero-tolerance statute, they cannot also prosecute a standard DUI or DUAC from the same incident.
• Commercial drivers: the threshold drops to .04% in a commercial vehicle. A first violation disqualifies the CDL for at least a year — three years if hauling placarded hazardous materials — and even a measurable amount below .04% puts the driver out of service for 24 hours. For anyone who drives for a living, the criminal case is often the smaller half of the problem.
• Out-of-state drivers: South Carolina can’t take a license another state issued, but it will suspend your privilege to drive here and report the case through the interstate compact — after which your home state typically imposes its own reciprocal penalties. Compliance is manageable from out of state: the Interstate ADSAP office can approve an equivalent program near you, and the major interlock vendors operate nationally with devices calibrated to South Carolina’s reporting rules.
• Drug DUI: § 56-5-2930 covers drugs and drug-alcohol combinations, but there is no per se limit for controlled substances. The State must prove material and appreciable impairment, often through Drug Recognition Expert testimony and a blood or urine sample — both of which present their own challenge points.

How a DUI Case Actually Moves Through York County

Where your case is heard depends on who arrested you and what you’re charged with:

• Rock Hill Municipal Court (120 E. Black Street) hears misdemeanor DUI arrests made by Rock Hill city police.
• The York County Centralized DUI Court — Courtroom B at the Moss Justice Center, 1675 York Highway in York — consolidates first-offense DUI and DUAC tickets written by the Highway Patrol, the York County Sheriff’s Office, Fort Mill police, and the multi-jurisdictional task forces. The 16th Circuit Solicitor’s Office staffs it with a dedicated DUI unit.
• The Court of General Sessions, also at the Moss Justice Center, takes every felony DUI and every second-or-subsequent offense.

The typical sequence: processing at the Rock Hill Police Department or the York County Detention Center, a bond hearing before a magistrate within 24 hours at the Moss Justice Center, then — where a refusal or .15%+ test triggered a suspension — the 30-day OMVH window running in parallel with the criminal docket. Discovery is where a DUI defense is usually built — the incident-site and breath-site videos, the SLED maintenance and calibration records for the specific DataMaster DMT machine used, and the officer’s reports all get pulled and measured against the statutes above. York County doesn’t publish case-length statistics, but structurally, summary-court cases can take several months to reach trial posture, while General Sessions cases routinely run more than a year.

One more York County reality: the diversion programs that soften other charges mostly don’t apply here. DUI is statutorily ineligible for Pre-Trial Intervention and the Alcohol Education Program, and the Traffic Education Program excludes DUI outright. That’s precisely why the defense levers — the stop, the video, the testing protocol — carry the weight they do. They’re the ones actually available. An experienced criminal defense attorney who works these courtrooms week in and week out knows which levers fit which case.

Can a South Carolina DUI Be Expunged? (And the Reckless-Driving Question)

No. This surprises almost everyone: a South Carolina DUI or DUAC conviction can never be expunged. Like other motor vehicle traffic convictions, DUI and DUAC fall outside South Carolina’s expungement statutes, so a conviction is permanent — which is exactly why the fight happens before conviction, not after. If your charge is dismissed or you’re acquitted, that’s a different story: under § 17-1-40, the arrest and booking records are eligible for destruction, and our guide to South Carolina expungement covers how that process works.

The other path clients ask about is reducing a DUI to reckless driving (§ 56-5-2920). It happens, but the law constrains it: South Carolina restricts plea reductions in impaired-driving cases, and a solicitor agreeing to a reduction beyond the next-lesser offense must put compelling reasons for it on the court record. Worth knowing even then: reckless driving is also a traffic offense that can’t be expunged — its value is avoiding the alcohol-related conviction and with it the interlock, ADSAP, and the SR-22 high-risk insurance certificate.

What This Means If You’ve Just Been Arrested

Three things matter in the first month, in order: the 30-day OMVH deadline if your license was administratively suspended for a refusal or a .15%+ test (miss it and the suspension simply takes effect), preservation and review of every required video, and understanding which offense — DUI or DUAC — the State is actually pursuing, because the defense follows the charge. The penalties in this guide are what the statutes authorize; what happens in an individual case depends on the evidence, the procedure the officers actually followed, and the arguments made at each step.

South Carolina DUI: Quick Answers

Can a DUI be expunged in South Carolina?

No. DUI and DUAC convictions are permanently ineligible for expungement in South Carolina. Only if the charge is dismissed or you are acquitted can the arrest records be destroyed under § 17-1-40.

What is the difference between DUI and DUAC?

DUI requires the State to prove your faculties were materially and appreciably impaired. DUAC only requires proof that you drove with a BAC of .08% or higher within two hours of arrest — impairment doesn’t matter. You cannot be prosecuted for both from the same incident.

What happens if I refuse the breathalyzer in South Carolina?

Your license is administratively suspended for six months (nine for a second refusal within ten years), and the refusal can be used as evidence at trial. You have 30 days to request an OMVH hearing ($200 fee) and obtain a $100 Temporary Alcohol License that restores unrestricted driving while the hearing is pending.

Is jail mandatory for a first-offense DUI in South Carolina?

The statute sets 48 hours to 30 days for a first offense under .10% BAC, rising to a 30-day minimum at .16% or higher — but for a first offense the judge may allow the minimum to be served as public service hours instead (48 hours, 72 hours, or 30 days depending on tier).

Do first-time offenders need an ignition interlock in South Carolina?

Yes. For violations on or after May 19, 2024, South Carolina requires an ignition interlock device for every DUI/DUAC conviction — including first offenses under .15% BAC — for six months, and the old provisional and route-restricted licenses no longer exist for these cases.

Which court handles DUI cases in Rock Hill and York County?

Rock Hill city arrests go to Rock Hill Municipal Court. First-offense cases from the Highway Patrol, Sheriff’s Office, and Fort Mill police go to the York County Centralized DUI Court at the Moss Justice Center. Felony DUI and repeat offenses go to the Court of General Sessions.
