The DUI Law in Mississippi
Drunk driving is charged as DUI in Mississippi, at a blood alcohol level of 0.08 or more.
Driving in Mississippi 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 Public Safety, separately from the criminal case.
Who Makes DUI Arrests in Union County
The Union County Sheriff's Office and the agencies that report for New Albany, Myrtle and Blue Springs make the DUI arrests in Union County.
The FBI's agency list also places one more agency in Union County: New Albany Commercial Transportation Enforcement Division (state agency).
Together, the three agencies in Union County with all twelve months of 2025 on file reported 310 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 63 people on an average day in 2019 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at unioncoms.com/sheriff. The Union County inmate search guide covers the jail in full.
The Court Case
A DUI charge from Union County is heard in the Justice Court or a municipal court; the District Attorney or, in a municipal court, the city's own prosecutor brings it.
The court records page SearchSystems verified for the county is at courts.ms.gov.
Mississippi 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 Public Safety runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Mississippi Department of Public Safety Driver Service Bureau 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 Mississippi Public Records Act.
- The court file: from the Justice Court or a municipal court, kept by the Circuit Clerk for criminal and civil cases and the Chancery Clerk for divorces, estates and land records.
- The driving record: from the Mississippi Department of Public Safety Driver Service Bureau.
