What Happens if You Get a Second DUI in Tennessee?

 Posted on August 27, 2026 in DUI/DWI/BUI

A second DUI in Tennessee carries much harsher penalties than a first offense. This includes mandatory jail time, a longer license revocation, and higher fines. This can feel especially frightening if you're worried about your job, your family, and what your future looks like now.

If you've been charged in 2026, talk to our Anderson County DUI defense lawyer. He can help you understand what you're up against and explain your defense options.

How Does Tennessee Define a Second DUI Offense?

Under Tennessee Code Annotated Section 55-10-401, a person commits DUI by driving while under the influence of alcohol, drugs, or certain other intoxicating substances. The law also prohibits driving with a blood or breath alcohol concentration of 0.08 percent or higher in most cases.

Under Tennessee Code Annotated Section 55-10-405, a prior DUI generally counts toward repeat-offender penalties when the prior violation occurred within 10 years of the current violation. The timing and type of any prior convictions therefore matter when determining whether a new DUI will be treated as a second offense.

What Mandatory Jail Time Comes With a Second DUI?

Under Tennessee Code Annotated Section 55-10-402, a second DUI carries a sentence of at least 45 days and up to 11 months and 29 days. However, Tennessee law provides a treatment option in some cases. After serving at least 17 days in jail or a workhouse and completing a substance abuse assessment, a judge may order qualifying treatment as a condition of probation.

Successful participation in an approved treatment program can provide credit toward the remaining period of confinement. This means a second DUI still carries a serious mandatory sentence. But not every person must necessarily serve the entire 45 days physically in jail.

How Long Will Your License Be Revoked for a Second DUI in TN?

A second DUI conviction means your license gets taken away for two years. That's much longer than the one-year revocation you'd get for a first DUI.

You might be able to get a restricted license during this time. To use one, Tennessee generally requires you to install and keep an ignition interlock device in your car. You'll also need SR-22 insurance and meet other requirements to qualify.

What Defenses Are Available for a Second DUI Charge in Tennessee?

Several defense strategies may apply depending on your specific situation. Common defenses include:

• Challenging whether the traffic stop was legally justified
• Questioning the accuracy or administration of field sobriety tests
• Disputing the reliability of breath or blood test results
• Reviewing whether your prior conviction actually qualifies as a valid predicate offense under Tennessee law

Errors or irregularities in how that prior case was handled can sometimes affect how your current charge gets treated. That’s why a careful review of each of these areas is important, and we can help.

Can You Avoid the Mandatory Minimum Jail Time for a Second DUI in TN?

This depends heavily on the specific facts of your case. If your attorney can successfully poke holes in the state's overall case, this may lead to a reduced charge that doesn't carry the same mandatory minimum sentence.

This is why building a strong defense against the charge itself often matters more in a second offense case than focusing solely on sentencing arguments.

What Should You Do if You're Facing a Second DUI Charge?

Acting fast can make a difference in protecting your defense. Stick to basic information when talking to police, and don't say anything beyond that. Ask for copies of any field sobriety test recordings or dashcam footage. Then reach out to a defense attorney as soon as you can to go over your case.
