A DUI in South Carolina becomes a felony when impaired driving causes great bodily injury or kills another person. Under South Carolina Code 56-5-2945, a felony DUI in South Carolina carries mandatory prison time of 30 days to 15 years when someone is seriously hurt, and 1 to 25 years when someone dies, along with fines up to $25,100, an automatic license suspension, and years of driving with an ignition interlock device after release.1South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2945 It also brings consequences that outlast the sentence: a permanent felony record, the loss of firearm rights, and exposure to civil lawsuits from victims and their families.
What Turns a DUI Into a Felony
A standard DUI is a misdemeanor. It becomes a felony only when an impaired driver causes “great bodily injury” or death to someone else. South Carolina defines great bodily injury as harm that creates a substantial risk of death, causes serious permanent disfigurement, or results in the long-term loss or impairment of a body part or organ.1South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2945 A broken arm that fully heals probably doesn’t meet that bar. A traumatic brain injury, loss of a limb, or organ damage almost certainly does.
The statute reaches impairment from alcohol, drugs, or any combination. The substance can be illegal, prescription, or over-the-counter. If impairment contributed to a crash that caused serious injury or death, the felony charge applies.
Felony DUI is not an intent crime. Prosecutors do not have to prove the driver meant to hurt anyone. They have to prove two things beyond a reasonable doubt: that the driver was impaired, and that the impairment directly caused the injury or death. Being drunk and being in a crash is not enough on its own. There must be a causal link.1South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2945
Prison Time and Fines
Felony DUI sentences are mandatory. A judge cannot swap the prison term for probation or community service.
When great bodily injury results:
- Prison: 30 days to 15 years, mandatory
- Fine: $5,100 to $10,100
When death results:
- Prison: 1 year to 25 years, mandatory
- Fine: $10,100 to $25,100
Sentences are served in the South Carolina Department of Corrections.1South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2945 The fines do not include court costs, fees, or restitution owed to victims, all of which stack on top.
Parole Eligibility
Parole is available, but not quickly. Felony DUI is classified as a violent crime in South Carolina, and a convicted person must serve at least one-third of the sentence or the mandatory minimum portion, whichever is longer, before becoming eligible.2South Carolina Legislature. South Carolina Code Title 24 Chapter 21 Section 24-21-610 On a 15-year great-bodily-injury sentence, that is at least five years before parole is even on the table. Eligibility does not mean release. The Parole Board decides case by case.
After Release
Release often comes with probation and strict conditions: regular check-ins with a probation officer, random drug and alcohol testing, substance abuse treatment, and community service or victim impact panels. A probation violation can send you back to prison.
License Suspension and Ignition Interlock
A felony DUI conviction triggers an automatic license suspension by the South Carolina Department of Motor Vehicles. The suspension remains in effect through incarceration. After release, you must enroll in the Ignition Interlock Device Program and drive on an interlock-restricted license. The device must stay on your vehicle for three years if the conviction involved great bodily injury, or five years if someone died.1South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2945
The interlock requires a breath sample before the car will start and random retests while you drive. Installation and monthly monitoring fees come out of your pocket for the full interlock period.
South Carolina’s implied consent law also matters here. Drivers involved in serious or fatal crashes are required to submit to chemical testing. Refusing triggers a separate administrative suspension of at least six months, which you can end early by enrolling in the Ignition Interlock Device Program.3South Carolina Legislature. South Carolina Code Title 56 Chapter 5 Section 56-5-2950 Refusal does not block a felony DUI prosecution. Officers can still make the case with other evidence, and the refusal itself can be used in court.
ADSAP and Reinstatement
Before full driving privileges can be restored, the DMV requires completion of the Alcohol and Drug Safety Action Program (ADSAP). The program assesses the substance use issues behind the offense and builds an individualized education or treatment plan. The educational component costs $500, and if treatment is required, the total can reach $2,500. Failing to enroll within 30 days of being ordered can result in contempt, and the DMV will not reinstate anything until it receives confirmation of enrollment and completion.4South Carolina Department of Alcohol and Other Drug Services (DAODAS).

You will also need SR-22 insurance, a high-risk policy an insurer files with the state to certify minimum coverage. Expect to carry it for at least three years, with sharply higher premiums.
Consequences That Outlast the Sentence
The collateral damage from a felony DUI often surprises people more than the sentence itself.
Firearm Rights
A felony DUI conviction permanently strips your right to possess firearms under federal law. It does not matter that the felony involved driving rather than violence. Federal law bars anyone convicted of a crime punishable by more than one year of imprisonment from possessing, purchasing, or receiving firearms or ammunition.5Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts Felony DUI in South Carolina carries a maximum of 15 to 25 years, so the ban applies. Violating it is a separate federal felony.
No Expungement
A felony DUI cannot be expunged in South Carolina. DUI convictions of any kind are excluded from expungement eligibility.6South Carolina Judicial Branch. FAQ about Expungements and Pardons The conviction stays on your record permanently. A pardon from the state’s Probation, Parole, and Pardon Services Board is possible, but a pardon ends ongoing penalties without erasing the record.
International Travel
A felony DUI makes you inadmissible to Canada. Canadian immigration treats impaired driving as serious criminality, and entry requires a Temporary Resident Permit or formal Criminal Rehabilitation. Other countries may restrict entry as well.
Employment and Housing
Felony convictions appear on background checks and can block jobs that require a clean record, professional licenses, or security clearances. Many landlords screen for felony convictions. These barriers tend to persist well after release.
Commercial Driver’s License Holders
If you hold a CDL, federal rules add another layer. Using any vehicle to commit a felony means a one-year CDL disqualification for a first offense, three years if the vehicle was carrying hazardous materials, and lifetime disqualification for a second conviction. A state may reinstate a CDL after 10 years and completion of an approved rehabilitation program, but another disqualifying conviction after that makes the lifetime bar permanent, with no further reinstatement.7eCFR. 49 CFR Part 383 Subpart D – Driver Disqualifications and Penalties For anyone whose work depends on a CDL, a felony DUI effectively ends that career for years, if not for good.
Civil Lawsuits From Victims
The criminal case is only half of the exposure. Victims and their families can bring a separate civil lawsuit for money damages. In a wrongful death action, South Carolina law allows a jury to award damages proportional to the injury caused by the death, including pre-death medical costs, funeral expenses, and the loss of the deceased person’s future earnings and companionship.8South Carolina Legislature. South Carolina Code of Laws Title 15 Chapter 51 – Section 15-51-40
South Carolina law also permits “exemplary damages” (the state’s term for punitive damages) in wrongful death cases where the conduct was reckless, willful, or malicious.8South Carolina Legislature. South Carolina Code of Laws Title 15 Chapter 51 – Section 15-51-40 Driving heavily impaired and killing someone is the sort of conduct juries tend to punish aggressively. Civil judgments stand independent of the criminal penalties, so a defendant can be paying court-ordered restitution and a civil judgment at the same time.
How the Case Is Proven and Defended
To establish impairment, prosecutors use breathalyzer results, blood tests, field sobriety tests, officer observations, and witness statements. To prove causation, they often rely on accident reconstruction experts who analyze skid marks, vehicle damage, road conditions, and the sequence of events.
Felony DUI cases are defensible, but the window for building a defense closes fast. Dashcam footage, breathalyzer calibration records, and blood sample chain-of-custody logs need to be preserved early. Waiting weeks to hire counsel can mean key evidence is gone or harder to challenge.
Defenses typically target the two elements the state must prove. On impairment, the defense may challenge breathalyzer calibration, blood draw procedures, or whether field sobriety tests followed standardized protocols. On causation, reconstruction evidence can sometimes show the crash was caused by road conditions, mechanical failure, or another driver’s actions rather than impairment. Constitutional challenges are available when officers violated the driver’s rights during the stop, arrest, or testing.
Where the prosecution’s evidence has gaps, an attorney may negotiate a reduction to a misdemeanor DUI or reckless driving. The gap between a felony conviction and a misdemeanor is enormous: prison time, firearm rights, and a permanent record all turn on it. With mandatory minimums and the reach of the collateral consequences, early legal representation matters.
