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.

Tennessee 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 Safety and Homeland Security runs a separate administrative case over the license, which can suspend it before the criminal case is decided, and the Tennessee Department of Safety and Homeland Security keeps the driving record the conviction goes on.
