Tennessee DUI Laws
Administrative: This happens immediately if your blood alcohol concentration (BAC) is .08 or over or if you refuse a test. If you fail your breath test, your arresting officer will take your license and issue a notice of revocation. This is your temporary driving permit, which allows you to drive for 10 days. You can challenge your suspension within those 10 days. If you do not choose to challenge your suspension, or if the hearing is not decided in your favor, the revocation stands. If this is your 1st or 2nd offense, you may be eligible for a restricted license.
This occurs if you are convicted in court or plead guilty to DUI. A Tennessee 1st offense DUI conviction carries penalties that include fines, jail time, license suspension and installation of an ignition interlock at your expense. More details on DUI offenses and penalties can be found on the Tennessee Department of Safety and Homeland Security website.
