Overview
South Carolina has one of the more complex DUI penalty structures in the country, with penalties that vary based on both BAC level and number of prior offenses. The state uses a 10-year lookback period for DUI enhancements, and a fourth DUI offense is a felony regardless of when prior offenses occurred (lifetime lookback for felony threshold). South Carolina is notable for its 'implied consent' video recording requirement — officers must videotape the administration of breathalyzer tests and field sobriety tests, and failure to do so can result in suppression of evidence. The state's 'Emma's Law' (2014) expanded mandatory IID requirements significantly for first offenders with high BAC levels.

Implied Consent Law
Under S.C. Code § 56-5-2950, any person operating a motor vehicle in South Carolina is deemed to have consented to chemical testing of breath, blood, or urine when an officer has probable cause for DUI. South Carolina is unique in requiring officers to videotape the DUI stop, field sobriety tests, and breathalyzer administration — a failure to record can result in suppression of evidence and potential case dismissal.
Refusal penalties: First refusal: 6-month license suspension (may obtain temporary alcohol license for 30 days). Second refusal: 9-month suspension. Third or subsequent refusal: 12-month suspension. The refusal triggers an administrative hearing with the SCDMV. A refusal does not result in criminal penalties by itself, but it can be introduced as evidence at the DUI trial. Under Emma's Law, an IID-restricted license is available for refusal suspensions.
Aggravating Factors
| Factor | Impact |
|---|---|
| BAC of 0.10% to 0.159% (elevated tier) | Increased mandatory minimum jail time and higher minimum fines at each offense level compared to standard BAC |
| BAC of 0.16% or higher (highest tier) | Significantly increased mandatory minimums: 30 days (1st), 90 days (2nd), 6 months (3rd). Higher minimum fines. Mandatory IID under Emma's Law. |
| Child passenger under 16 in vehicle | Separate felony charge of child endangerment; DUI penalties enhanced; potential SCDSS involvement |
| Causing great bodily injury or death while DUI | Felony DUI resulting in great bodily injury: up to 15 years prison with mandatory 30-day minimum. Felony DUI resulting in death: up to 25 years prison with mandatory 1-year minimum. |
| Driving on DUI-suspended license | Separate misdemeanor: first offense 30 days to 6 months jail; second offense 60 days to 1 year; subsequent offenses 6 months to 3 years. Vehicle may be confiscated. |
| Prior felony DUI conviction | Lifetime lookback for felony threshold; any 4th DUI offense is a felony regardless of the time elapsed between prior offenses |
DUI with Injury
Classification: Felony
Felony DUI resulting in great bodily injury (S.C. Code § 56-5-2945) carries a mandatory minimum of 30 days and up to 15 years in prison, plus fines and license revocation. Felony DUI resulting in death carries a mandatory minimum of 1 year and up to 25 years in prison. If the offender's BAC was 0.16% or higher, mandatory minimums are enhanced further. Restitution to the victim is mandatory. The offender's license is permanently revoked for vehicular DUI death.
Underage DUI
Drivers under 21 with a BAC of 0.02% or above but below 0.08% face a 3-month license suspension for a first violation and a 6-month suspension for subsequent violations through the SCDMV. This is an administrative penalty, not a criminal charge. If the underage driver's BAC is 0.08% or above, full criminal adult DUI penalties apply. Underage drivers may also face separate charges under South Carolina's underage possession of alcohol laws.
Diversion Programs
Program: Pre-Trial Intervention (PTI) / ADSAP
South Carolina's Pre-Trial Intervention (PTI) program may be available for first-time DUI offenders in some judicial circuits, though availability varies significantly by county. The state's primary alternative is the Alcohol and Drug Safety Action Program (ADSAP), which is mandatory for all DUI convictions and provides assessment, education, and treatment. Successful ADSAP completion is required for license reinstatement. Some circuits also offer DUI Court programs for repeat offenders.
Eligibility: PTI availability for DUI cases varies by judicial circuit and solicitor's office. Where available, it is typically limited to first-time offenders with no prior criminal history and BAC below 0.10%. The defendant must consent to enrollment and comply with all conditions. ADSAP is not a diversion program per se — it is mandatory for all DUI convictions — but its completion requirements effectively function as rehabilitative conditions.
How Long a DUI Stays on Your Record
A DUI conviction remains on your South Carolina driving record for at least 10 years and on your criminal record permanently. The SCDMV maintains DUI records indefinitely for felony lookback purposes. South Carolina allows expungement of first-offense DUI convictions under S.C. Code § 56-5-2990 if: it was a first offense, the person was not convicted of any other DUI offense during the 10-year lookback, and the conviction did not involve death or great bodily injury. Second and subsequent DUI convictions and felony DUI are not eligible for expungement.
