Tennessee DUI State Laws

You are here: Home / State Laws / Tennessee DUI State Laws

tennesseeTennessee State Law

Tennessee DUI cases are unique, since there is no pre-trial administrative driver’s license suspension, as there is in many other states. The only driver’s license consequences are the ones imposed by the court.

Tennessee ignition interlocks are court-ordered even for a first time DUI offenders. After serving a period of license suspension or revocation, offenders may be allowed to drive while using the device. After serving twelve months of the revocation period, a second time DUI offender may apply for a restricted license. After two DUIs, offenders do not qualify for restricted licenses, which allow individuals to drive while using an interlock device.

The offender must have the IID serviced by the service provider at least semi-annually. The offender must provide the court with proof of IID installation and proof of periodic maintenance. The offender is responsible for obtaining the documentation from the service provider.
