The DUI Law in South Carolina
Drunk driving is charged as DUI in South Carolina, at a blood alcohol level of 0.08 or more.
Driving in South Carolina is consent to a breath or blood test when an officer has cause to suspect DUI; the license case that follows a refusal or a failed test is run by the Department of Motor Vehicles, separately from the criminal case.
For charging and sentencing, South Carolina counts prior offenses within 10 years.
Who Makes DUI Arrests in Union County
The Union County Sheriff's Office and the agencies that report for Union and Jonesville make the DUI arrests in Union County.
The FBI's agency list also places five state agencies and one state police unit in Union County (the arrest records guide names each one); the Highway Patrol in Union County makes the arrests on the state highways.
Together, the two agencies in Union County with all twelve months of 2025 on file reported 609 arrests to the FBI that year, all offenses together; the FBI's count for Union County does not break DUI out.
Booking After a DUI Arrest in Union County
A driver arrested for DUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Union County Sheriff's Office, held about 82 people on an average day in 2021 by the Vera Institute of Justice's count.
The Court Case
A DUI charge from Union County is heard in a Magistrate or Municipal Court; the Solicitor or, in a municipal court, the city's own prosecutor brings it.

South Carolina has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
The court case is only half the record. The Department of Motor Vehicles runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the South Carolina Department of Motor Vehicles keeps the driving record the conviction goes on.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the South Carolina Freedom of Information Act.
- The court file: from a Magistrate or Municipal Court, kept by the Clerk of Court.
- The driving record: from the South Carolina Department of Motor Vehicles.
