What are the mandatory penalties for a first DUI in Tennessee?

On Behalf of | Sep 11, 2026 | CRIMINAL LAW - Drunk Driving

A first DUI conviction in Tennessee carries penalties that courts must impose. Under state law, those penalties include jail time, a fine and a one-year revocation. For many drivers, the question is not whether a judge can waive those basic penalties. The real issue is what Tennessee law requires on a first conviction and which added conditions usually follow.

Tennessee law requires jail, fines and a one-year revocation

Tennessee law sets a minimum sentence for a first DUI conviction. That sentence includes at least 48 hours in jail, a fine between $350 and $1,500 and a one-year loss of driving privileges.

Public information on driver licensing and related safety requirements in Tennessee explains the administrative side of revocation and reinstatement.

Additional conditions often follow the core sentence

Beyond the required minimums, Tennessee courts often impose added conditions as part of the case. These include:

  • Alcohol or drug assessment
  • Participation in treatment or education as ordered
  • An ignition interlock device requirement upon license reinstatement

Finishing the criminal sentence does not automatically restore driving privileges. A driver must still complete added steps before becoming eligible to drive again.

Evidence and procedure determine how the case resolves

Required minimums do not mean every first DUI case resolves the same way. The traffic stop, chemical testing, statements to law enforcement and the way local prosecutors handle DUI cases all shape the result. An attorney who handles DUI charges and other driving-related offenses can identify which penalties Tennessee law fixes and whether the state’s proof leaves room for a challenge.
