How do penalties differ for underage DUIs compared to adult DUIs?
Answer:
The consequences depend on the driver’s age, the charge, and the court with jurisdiction. South Carolina’s under-21 licensing procedure uses a 0.02% alcohol threshold, but that is separate from proving criminal DUI. Juvenile proceedings can also involve different dispositions from adult criminal cases.
Legal clarification — October 16, 2026: The under-21 0.02% threshold concerns administrative licensing under § 56-1-286; it does not automatically establish criminal DUI. Age and traffic-court jurisdiction rules also affect which court handles a younger driver’s case.
Comparing underage and adult DUI consequences requires looking at more than the driver’s alcohol reading. The driver’s age, the alleged offense, and the court handling the case all matter.
South Carolina has an administrative licensing procedure for drivers under 21 with an alcohol concentration of 0.02% or more. That threshold does not automatically establish a criminal DUI offense or simply replace the alcohol-related inference rules used in a criminal prosecution.
For younger drivers, the court’s jurisdiction also needs careful review. Juvenile proceedings differ from adult criminal prosecutions, and traffic matters have particular jurisdictional rules. Being under 21 does not by itself mean a case belongs in family court.
Where a case proceeds through the juvenile system, possible dispositions can include supervision, programs, or placement, depending on the law and the individual circumstances. Juvenile proceedings can still have serious consequences even though they differ from adult criminal court.
A DUI defense attorney can identify the applicable court, distinguish licensing issues from the criminal charge, and explain the options available in the individual case.
