DUI in South Carolina
State-specific overview · Criminal Law
South Carolina enforces a strict zero-tolerance policy for drivers under 21 and requires mandatory minimum jail sentences for all DUI convictions.
How South Carolina treats DUI
South Carolina prohibits driving with a BAC of 0.08% or higher for drivers 21 and older, but enforces a zero-tolerance policy (0.02% BAC) for drivers under 21 and commercial drivers. All DUI convictions carry mandatory minimum jail sentences: 48 hours for first offense, 5 days for second offense, and 60 days for third offense, with escalating penalties thereafter. The state also recognizes a separate offense for driving under the influence of drugs or a combination of alcohol and drugs. South Carolina's implied consent law requires submission to breath or blood testing, and refusal results in automatic license suspension and enhanced criminal penalties.
The general definition of DUI
Driving under the influence of alcohol or drugs, a serious criminal offense.
DUI stands for Driving Under the Influence and means operating a vehicle while impaired by alcohol, drugs, or both. You can be charged with DUI even if your blood alcohol level is below the legal limit if your driving is noticeably impaired. Penalties vary by jurisdiction and whether it's a first or repeat offense, but typically include fines, license suspension, jail time, and mandatory alcohol education programs. A DUI conviction has lasting effects on insurance rates, employment, and your driving record.
