Will You Go to Jail for a First DUI in Tennessee?
A first DUI conviction in Tennessee carries a mandatory minimum jail sentence of 48 consecutive hours. If your blood alcohol concentration (BAC) was 0.15% or higher, the minimum increases to seven consecutive days. The law allows a sentence of up to 11 months and 29 days, although the outcome depends on the charge, the evidence, and the circumstances of the case.
Being arrested for DUI is not the same as being convicted. Prosecutors must prove the charge, and the evidence may raise questions about the traffic stop, the officer's observations, or the reliability of chemical testing. Before assuming jail time is unavoidable, it is important to understand what the state can actually prove.
What Are the Penalties for a First DUI in Tennessee?
A first-offense DUI is generally a Class A misdemeanor. If convicted, a driver may face:
- Jail: At least 48 consecutive hours, or seven consecutive days if the BAC was 0.15% or higher.
- Fines: $350 to $1,500, plus applicable court costs.
- Driver's license revocation: Generally one year.
- Alcohol and drug education: Required assessments, programs, or treatment as applicable.
- Ignition interlock: Requirements that depend on the circumstances and the type of driving privileges sought.
- Probation: Possible supervision and conditions in addition to any required incarceration.
Additional penalties may apply when a child was in the vehicle or when the incident involves other criminal charges. Tennessee's DUI sentencing rules are found in Tennessee Code §§ 55-10-402 and 55-10-403.
Does Everyone Convicted of a First DUI Serve Jail Time?
Tennessee law establishes mandatory incarceration for a first DUI conviction, but not every person arrested for DUI is ultimately convicted of that offense.
The distinction matters. A DUI charge may be dismissed if the prosecution cannot establish the required elements or if important evidence is excluded. In other cases, negotiations may lead to a different charge, depending on the evidence and the prosecutor's position. Neither outcome is automatic.
Even when a DUI conviction occurs, the length and conditions of the sentence require careful review. An attorney can explain which statutory requirements apply and whether any lawful sentencing alternatives are available.
What Happens After Your First DUI Arrest?
After an arrest, you will receive information about your charge and court appearance. The case may involve several stages, including reviewing the evidence, appearing in court, discussing possible resolutions, and preparing for hearings or trial if necessary.
The evidence can include dashcam or bodycam recordings, the arresting officer's report, field sobriety test observations, witness statements, and breath or blood test records. Reviewing that material early helps identify factual disagreements and potential legal issues.
A first DUI case should not be evaluated solely by the BAC reported on a citation. The legality of the stop, the procedures used to collect evidence, and the accuracy of the prosecution's account can all matter.
Can You Lose Your License After a First DUI?
A first DUI conviction generally carries a one-year driver's license revocation in Tennessee. Depending on the circumstances, some drivers may qualify for restricted driving privileges, often with an ignition interlock requirement.
License issues can also arise separately from the criminal DUI charge, particularly when chemical testing was refused. Because the rules differ depending on the reason for the license action, it is important to determine which process applies before making plans to drive.

Can a First DUI Be Reduced or Dismissed in Tennessee?
A first DUI charge can sometimes be reduced or dismissed, but the outcome depends on the specific evidence and legal circumstances.
For example, a traffic stop may be challenged if the officer lacked a lawful basis to stop the vehicle. Video footage may contradict statements in a police report, or chemical testing records may raise questions about how a sample was collected and analyzed.
Herbert & Lux has handled DUI cases in which examining the evidence made a meaningful difference. In one Sumner County case, a first DUI charge was reduced to reckless driving with no probation after testing showed no alcohol and the case involved prescribed medication. That result was specific to the evidence in that matter and does not guarantee a similar result in another case.

Does a First DUI Stay on Your Record?
A DUI conviction in Tennessee generally cannot be expunged. That makes the distinction between an arrest, a dismissed charge, a reduced charge, and a DUI conviction especially important.
The eligibility of a dismissed or reduced charge for expungement depends on the final disposition and applicable Tennessee law. Do not assume that a reduced charge automatically qualifies for removal from your record.
What Should You Do After a First DUI Charge?
Start by keeping your citation, bond paperwork, court notices, and any other documents related to the arrest. Write down what you remember about the stop and testing while those details are still fresh, and avoid discussing the facts of the case publicly.
An attorney can review the charge, explain upcoming court obligations, and help identify which evidence should be requested. Taking the charge seriously from the beginning is important, even if you have never been in trouble before.
