The DUI Law in Tennessee
In Tennessee the offense is DUI, and the limit is 0.08.
Driving in Tennessee 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 Safety and Homeland Security, separately from the criminal case.
For charging and sentencing, Tennessee counts prior offenses within 10 years.

Booking After a DUI Arrest in Knox 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 Knox County Sheriff's Office, held about 1,310 people on an average day in 2024 by the Vera Institute of Justice's count and has a jail page SearchSystems verified at sheriff.knoxcountytn.gov, phone 865-281-6700.

The Court Case
The District Attorney General files the charge, and the case is heard in the General Sessions Court.

The court records page SearchSystems verified for the county is at criminalcourt.knoxcounty.org/docket-search, phone (865) 215-2375. That page belongs to a lower court, the General Sessions Court, not to the Knox County Circuit and Chancery Courts.
Tennessee 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 Safety and Homeland Security. The driving record, kept by the Tennessee Department of Safety and Homeland Security, carries the result of both.
The Records a DUI Leaves
- The arrest report: from the agency that made the arrest, under the Tennessee Public Records Act.
- The court file: from the General Sessions Court, kept by the Circuit Court Clerk and the Clerk and Master.
