A DUI arrest in Nashville puts three things at risk at the same time: your freedom, your driver’s license, and your record. Those three tracks move on separate timelines. The criminal case runs through General Sessions and, if it is bound over, Criminal Court. The license side runs through the Department of Safety and can begin before you ever see a judge. Waiting to deal with one until the other is finished is how people lose the ability to drive to work for a year.

Tennessee DUI Penalties by Offense Level
Driving under the influence is defined at T.C.A. § 55-10-401. The penalties live at T.C.A. § 55-10-402, and they escalate sharply with each qualifying prior conviction.
| Offense | Mandatory minimum jail | Fine range | License revocation |
|---|---|---|---|
| First | 48 hours (7 days if BAC 0.20 or higher) | $350 – $1,500 | 1 year |
| Second | 45 consecutive days | $600 – $3,500 | 2 years |
| Third | 120 consecutive days | $1,100 – $10,000 | 6 years |
| Fourth or more (Class E felony) | 150 consecutive days, day-for-day | $3,000 – $15,000 | 5 years to life |
The jump from a first to a second offense is the largest practical step in Tennessee DUI law: forty-eight hours becomes forty-five consecutive days, and those days must be served in a continuous block rather than spread across weekends. A third offense carries 120 consecutive days. A fourth crosses into felony territory, where 150 days must be served day-for-day before any release eligibility.
Enhancements can attach on top of the base sentence. Where a passenger under eighteen was in the vehicle, Tennessee adds a mandatory thirty days of incarceration and a separate fine under T.C.A. § 55-10-402(d); where a child suffers serious injury, the exposure escalates into felony territory. Read more on DUI child endangerment. Where a crash causes death, the State may charge vehicular homicide under T.C.A. § 39-13-213, a Class C or Class B felony depending on the facts.
The Ten-Year Lookback: How Priors Are Counted
Tennessee uses a ten-year lookback window when counting prior DUI convictions for enhancement. The window is measured from the date of the prior conviction to the date of the new offense — not from arrest to arrest — and it is measured to the day. A prior that falls just inside the window can be the difference between a first offense with a forty-eight-hour floor and a second offense carrying forty-five days.
Because the enhancement depends on the State proving each prior, the priors themselves are a defense issue. If a certified judgment is defective, if the prior falls outside the ten-year window, or if the prior conviction was not a qualifying DUI, the enhancement can fall away even in a case where the current DUI is provable. An out-of-state conviction counts only if the offense is substantially similar to Tennessee’s statute and falls within the window. I pull and review the certified records in every repeat-offense case rather than accepting the State’s count.
Implied Consent: What Refusing a Test Costs
Tennessee’s implied consent law, T.C.A. § 55-10-406, treats driving as consent to a chemical test when an officer has probable cause. An implied consent violation is a separate matter from the criminal DUI charge, and it carries its own revocation:
- First violation: one-year revocation
- Second within ten years: two years
- Third: five years
- Fourth or subsequent: ten years
That revocation can attach even where the DUI charge itself is dismissed or reduced, because the two proceedings answer different questions. The statute also identifies circumstances that raise the stakes at § 55-10-406(f), including crashes involving injury or death, prior DUI convictions, and transporting a child under sixteen.
The calculation around refusal has shifted as electronic search warrants have become routine in Middle Tennessee. An officer denied a breath sample can often obtain a warrant for blood within the hour, which means a refusal may produce both a blood result and a separate revocation. See refusing a blood or breath test and our post on breathalyzer refusal in Tennessee.
Your License: Revocation, Restricted Driving, and Interlock
For most people the license is the part of a DUI that reshapes daily life. Tennessee’s restricted-license framework at T.C.A. § 55-10-409 allows a court to authorize driving for essential purposes — work, school, medical care, and court obligations — during a revocation period. The path back is narrower for repeat offenders: where a driver has a prior DUI conviction within the past ten years, the court is required to condition any restricted license on a vehicle equipped with a functioning ignition interlock device.
Interlock obligations run for the length the court sets and carry their own costs — installation, monthly monitoring, and calibration. A missed or failed reading generates a report that can trigger a violation. For details on getting back on the road, see reinstating your driving privileges.
Commercial drivers face a separate and stricter standard: a 0.04 blood alcohol concentration, and a disqualification that can end a career even where the personal license survives. If you hold a CDL, read CDL DUI in Tennessee.
What to Do in the First Days After a Nashville DUI Arrest
After a DUI arrest in Davidson County you will be booked, fingerprinted, and held for an observation period — usually eight to twelve hours — before bond can be posted. Most first-offense bonds run between $1,000 and $2,500. What you do in the days that follow shapes the case:
- Write down everything you remember about the stop while it is fresh: where you were coming from, what you had to eat and drink and when, what the officer said, what tests you were asked to perform, and on what surface.
- Preserve receipts, rideshare records, and phone data that establish a timeline.
- Photograph the roadway and shoulder where the field sobriety tests were administered — slope, gravel, and lighting matter.
- Note any medical condition, injury, or medication that affects balance, speech, or eye movement.
- Do not discuss the case on a recorded jail line or on social media.
- Calendar your court date and call a lawyer before it. Body-camera and dash-camera footage is not retained forever, and a preservation request early is worth more than a subpoena later.
How I Defend Tennessee DUI Cases
A DUI case is built from a chain of decisions an officer made in a short window of time. Each link has legal requirements attached, and each is a place the State’s case can fail.
The Stop
An officer needs reasonable suspicion to stop a vehicle. Weaving within a lane, a slow roll through a stop sign, or an anonymous call about a driver may or may not clear that bar, and the answer often lives on video rather than in the report. Where the stop was unlawful, everything that followed — the tests, the statements, the sample — is subject to suppression. See pretextual traffic stops in Tennessee.
Field Sobriety Tests
The three standardized tests — horizontal gaze nystagmus, walk-and-turn, and one-leg stand — are validated only when administered the way the training manual requires. Roadside conditions rarely match the manual. Slope, loose gravel, traffic passing at speed, footwear, age, weight, and inner-ear or knee problems all affect performance, and the scoring is an officer’s judgment recorded in the moment. Video of the tests frequently shows a steadier person than the report describes.
Breath and Blood Testing
A breath result depends on a properly maintained instrument, a certified operator, and a completed observation period. A blood result depends on a lawful draw, an intact chain of custody, correct storage, and a laboratory that followed its own protocol. I request maintenance and calibration records, operator certifications, and the underlying laboratory data rather than accepting a single number on a printout. Rising blood alcohol, medical conditions, and improper preservatives are all live issues in the right case.
The Prior Convictions
In a repeat-offense case, the priors carry the sentence. Certified judgments, the ten-year math, and whether an out-of-state conviction qualifies are all contestable. Defeating one prior can move a case from felony exposure back to misdemeanor sentencing.

The Nashville DUI Court Process
A misdemeanor DUI in Davidson County begins in General Sessions Court. The first setting is an arraignment, where the charge is read and counsel is entered. From there the case is reset for discovery and negotiation, and it can be resolved in Sessions, dismissed, or bound over to the grand jury. A felony DUI, or a case the defense elects to move, proceeds to Criminal Court on indictment, where motions practice and a jury trial are available.
Most of the work happens between settings: obtaining the video, the maintenance and laboratory records, and the certified priors, then filing motions that test the stop and the testing. A suppression motion filed with case citations and timestamps changes what the State is willing to offer, because it changes what the State can prove. For the wider picture, read what happens after a Nashville arrest.

Frequently Asked Questions
Can a Tennessee DUI be reduced to reckless driving?
It happens, but it is not routine and it is not a matter of asking. A reduction generally follows a proof problem — a questionable stop, a testing irregularity, or a video that does not match the report. The stronger the suppression issue, the more room there is to negotiate.
How long does a DUI stay on my record in Tennessee?
A DUI conviction in Tennessee is not eligible for expunction and remains on your record permanently. It counts as a prior for ten years for enhancement purposes, but the conviction itself does not come off. That permanence is the reason the outcome of the first case matters so much. See how long a DUI stays on your record.
Do I have to give a breath sample if I am stopped?
Under the implied consent statute, refusing when an officer has probable cause carries a revocation that is separate from the criminal case — one year on a first violation. Because officers can often obtain an electronic warrant for blood quickly, a refusal may result in both a blood draw and a revocation.
What is the difference between DUI and DUI by drugs?
The statute covers impairment by any intoxicant, including lawfully prescribed medication. There is no per se number for most drugs, so the State relies on officer observation, drug-recognition testimony, and a blood result showing presence rather than concentration. Presence is not the same as impairment, and that gap is where these cases are defended.
Will I lose my license before my court date?
The implied consent revocation moves on its own track and can begin before the criminal case concludes. Because the two proceedings are separate, both need to be handled from the start. A restricted license under § 55-10-409 may be available for essential driving.
Is a fourth DUI a felony in Tennessee?
Yes. A fourth offense, and any offense beyond it, is a Class E felony carrying a sentencing range of one to six years, with a mandatory minimum of 150 consecutive days served day-for-day before release eligibility. The count depends on qualifying priors within the ten-year window, which is why the priors themselves are litigated.
Should I plead guilty at the first court date?
Not before anyone has seen the evidence. At an arraignment the defense typically has no video, no maintenance records, and no laboratory file. A plea entered that morning forecloses every issue that has not been examined yet, on a conviction that cannot be expunged.
What does a DUI defense cost?
Most first-offense cases are handled on a flat fee, with the figure depending on whether the case is resolved in General Sessions or set for trial. Court-imposed fines, fees, and the insurance consequences of a conviction typically exceed the cost of defending the case. I quote the fee in the first meeting.
