Nashville DUI Laws 2026: What Drivers Need to Know
Tennessee DUI laws got significantly tougher in 2024 and 2026. Most people spending a weekend on Broadway have no idea. Here’s what changed and what it costs.
Nashville DUI laws are stricter than most visitors expect — and they got significantly tougher in 2024 and 2026 with new BAC thresholds and penalties. Tennessee has always taken drunk driving seriously. The recent changes mean the consequences are now more serious than ever.
This guide is for visitors, new residents, and anyone spending time in Nashville who wants to understand exactly where the legal lines are, what happens if you cross them, and what a DUI in Tennessee actually costs.
The BAC Limits: What’s Legal in Tennessee
0.08%
Standard Limit
Drivers 21 and older
0.04%
CDL Holders
Commercial drivers
0.02%
Under 21
Effectively zero tolerance
⚠ Critical — Most People Miss This
You can be charged with DUI below these limits. Tennessee law allows DUI charges based on observable impairment regardless of BAC. If an officer determines you are impaired — by alcohol, prescription medication, marijuana, or any other substance — you can be arrested even if your BAC reads below 0.08%. The BAC limit is a floor for automatic presumption of guilt, not a safe threshold.
The 2024 and 2026 Law Changes You Need to Know
The 0.15% Aggravated DUI Threshold (July 2024)
As of July 1, 2024, Tennessee created a new aggravated DUI category for drivers with a BAC of 0.15% or higher — roughly 5 beers for an average woman or 7 beers for an average man over two hours. At that level, the penalties escalate substantially. A first offense at 0.15% or above carries a mandatory minimum of 7 days in jail, compared to 48 hours at standard BAC levels.
Implied Consent Changes (January 2026)
Starting January 1, 2026, Tennessee’s implied consent law got significantly stricter:
- Refusing a blood test now triggers an automatic implied consent charge
- License suspension for refusal increased to 18 months for first-time DUI suspects with no prior record — up from 1 year
- Saliva tests are now authorized and results are admissible as evidence in court
Refusing a test is no longer a clean escape — it now carries its own substantial penalty on top of whatever DUI charges may follow.
Child Passenger Enhancements
If a child is in the vehicle, the BAC threshold for aggravated charges drops, and refusing a chemical test adds six months to your license suspension beyond the standard penalty. Having a child in the car while driving impaired escalates the charge significantly.
What Happens at a DUI Traffic Stop in Nashville
The stop: Nashville Metro Police patrol Broadway and the surrounding entertainment district aggressively, particularly on weekend nights and during major events like CMA Fest, NFL game days, and New Year’s Eve.
Field sobriety tests: The officer will likely ask you to perform standardized field sobriety tests — the horizontal gaze nystagmus test, walk-and-turn, and one-leg stand. These are voluntary in Tennessee, but refusing them doesn’t help your situation.
Breathalyzer: If the officer has probable cause to believe you’re impaired, they’ll request a breath test. Under Tennessee’s implied consent law, you are required to submit. Refusing triggers the automatic license suspension outlined above.
Blood/saliva test: In cases involving accidents, injuries, or drug impairment suspicion, a blood draw may be required. As of 2026, saliva tests are also now authorized and admissible in court.
Arrest: If you’re arrested, your vehicle will be towed and impounded at your expense. You’ll be taken to booking, processed, and held until you post bail.
First Offense DUI Penalties in Tennessee
A first DUI conviction in Tennessee is a Class A misdemeanor — the most serious misdemeanor classification in the state.
| Penalty | Standard (Under 0.15%) | Aggravated (0.15%+) |
|---|---|---|
| Jail time | Min. 48 consecutive hours | Min. 7 days |
| Maximum jail | 11 months, 29 days | 11 months, 29 days |
| Fines | $350–$1,500 | Higher at judge’s discretion |
| License revocation | Minimum 1 year | Minimum 1 year |
| Ignition Interlock Device | Required after reinstatement | Required after reinstatement |
| Treatment program | Mandatory | Mandatory |
The Real Cost
The true cost of a first DUI in Tennessee typically runs $10,000 to $25,000 when you factor in attorney fees, court costs, bail, towing and impound fees, IID installation and monthly fees, mandatory treatment program costs, increased insurance premiums, and lost wages. That’s not a worst-case scenario. That’s the realistic average.
Repeat Offense Penalties
Each subsequent DUI conviction within a 10-year period carries significantly escalated penalties:
Second offense: Minimum 45 days in jail. $600–$3,500 in fines. License revocation for 2 years. Vehicle may be seized on a second offense within 5 years.
Third offense: Minimum 120 days in jail. $1,100–$10,000 in fines. License revocation for 6 years.
Fourth offense and beyond: Felony DUI. Prison time, not jail. The trajectory from misdemeanor to felony happens faster in Tennessee than most people realize.
DUI and Accidents: When It Becomes a Felony
| Charge | Classification | Potential Sentence |
|---|---|---|
| Vehicular assault (DUI + serious injury) | Class D felony | Up to 12 years |
| Aggravated vehicular assault | Class C felony | Up to 15 years + $15,000 |
| Vehicular homicide (DUI + death) | Class C felony | 48 hours to 15 years |
| Aggravated vehicular homicide | Class A felony | 15 to 60 years + $50,000 |
Tennessee prosecutors pursue these charges. Nashville has seen high-profile vehicular homicide DUI cases result in decades-long sentences.
Nashville-Specific Enforcement
Broadway is one of the most heavily policed entertainment districts in the country on weekend nights. Nashville Metro Police run DUI checkpoints, saturation patrols, and designated plainclothes officer operations around the Lower Broadway corridor, particularly during CMA Fest, NFL season, New Year’s Eve, and major conventions.
Don’t Assume Lax Enforcement
The bachelorette party and tourist reputation of Nashville does not translate into lax enforcement. If anything, the volume of alcohol consumption downtown means law enforcement is more vigilant, not less. Officers on Broadway have seen every version of “I only had a couple drinks” and they are not moved by it.
The Rideshare Decision: Make It Before the First Drink
The decision to rideshare home needs to be made before you start drinking, not at the end of the night when your judgment is compromised and you’re trying to calculate whether you’re “okay to drive.”
Uber and Lyft both have strong coverage throughout Nashville. On weekend nights and during major events, surge pricing applies — but even a $40 rideshare home is a fraction of what a DUI costs in any scenario. Budget for the rideshare as part of your night out. It’s not an afterthought — it’s the plan.
If you’re staying near Broadway, many hotels are walking distance from the entertainment district. Walk home.
If You Are Charged: What to Do Immediately
- —Do not make statements without an attorney present. Be polite and cooperative, provide your license and registration, and submit to required chemical testing under implied consent law. Beyond that, exercise your right to remain silent.
- —Request an attorney immediately. You have the right to an attorney before questioning. Use it. A DUI attorney who knows Tennessee law and Nashville courts is not a luxury — it’s the difference between a navigable situation and a life-altering one.
- —Document everything you can remember. Where you were, what you consumed and when, who was with you, what the officer said and did. Do this as soon as you’re able. Details matter in DUI defense.
- —Request a hearing on your license suspension. In Tennessee, you have a limited window to request an administrative hearing to contest your license suspension. Missing this deadline means automatic suspension. Your attorney can handle this but you need to move quickly.

DUI Expungement in Tennessee
A first-offense DUI conviction in Tennessee is eligible for expungement after a 5-year waiting period. Expungement removes the conviction from your public record, which affects background checks, employment applications, and professional licensing. It does not erase the conviction from law enforcement databases.
If you have a DUI conviction and the waiting period has passed, consulting with a Tennessee attorney about expungement eligibility is worth doing. Learn more about Tennessee DUI expungement through LegalZoom here.
Nashville is one of the best cities in the country for a night out. None of that requires driving afterward. Plan the rideshare before the first drink. Walk when you can. Know where you’re staying relative to where you’re drinking. Nashville is set up for a great night — it just requires a little logistical thinking before the night starts rather than at the end of it.
