The DUI Law in Georgia
Drunk driving is charged as DUI in Georgia, at a blood alcohol level of 0.08 or more.
Driving in Georgia 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 Driver Services, separately from the criminal case.
For charging and sentencing, Georgia counts prior offenses within 10 years.
Who Makes DUI Arrests in Marietta
The Cobb County Sheriff's Office, the Cobb County Police Department and the agency that reports for Marietta (filed by the FBI as Marietta Police Department) make the DUI arrests in and around Marietta.
The FBI's agency list also places these agencies in Cobb County: Kennesaw State University (campus police); Cobb County Board of Education (other agency); the State Patrol at Marietta (state police); the State Patrol at Marietta makes the arrests on the state highways.

Booking After a DUI Arrest in Marietta
A driver arrested for DUI and kept in custody goes to the county jail, whichever agency made the arrest. The jail, run by the Cobb County Sheriff's Office, held about 2,140 people on an average day so far in 2026 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at cobbsheriff.org/inmates/adult-detention-center/custodial-information, phone (770) 528-8975. The Marietta inmate search guide covers the jail in full.
The Court Case
The District Attorney files the charge, and the case is heard in the State Court, or the Probate Court in counties without one.
The District Attorney's page SearchSystems verified is at cobbcounty.gov/district-attorney, phone (770) 528-3080.
The court records page SearchSystems verified for the county is at cobbcounty.gov/magistrate-court/magistrate-court-judicial-records-s..., phone (770) 528-8900. That page belongs to a lower court, the State Court and Magistrate Court, not to the Cobb County Superior Court.
Georgia has no single public index of every trial court case; each court's records are looked up through that court.
The License Case
A DUI arrest starts two cases: the criminal one above and an administrative one over the license, run by the Department of Driver Services. The driving record, kept by the Georgia Department of Driver Services, carries the result of both.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Georgia Open Records Act.
- The court file: from the State Court, or the Probate Court in counties without one, kept by the Clerk of Superior Court.
- The driving record: from the Georgia Department of Driver Services.
