DUI Defense in Tennessee — what to do right now

Right now, find your arrest or citation paperwork and look for the implied-consent notice. If you refused the breath, blood, or oral-fluid test, you have 10 days from your arrest to request an administrative hearing with the Tennessee Department of Safety and Homeland Security to contest the license revocation. Miss that window and the revocation locks in automatically, even if your criminal case is later dismissed. Before you call the court, call 1-844-690-0555 (free, 24/7) so you understand both tracks before any deadline passes.

The law in Tennessee: DUI Defense

In Tennessee, drunk driving is charged as DUI under Tenn. Code Ann. § 55-10-401. It's illegal to drive or be in physical control of a vehicle while under the influence, or with a blood-alcohol concentration of 0.08% or more — the 'per se' limit. Commercial drivers face a 0.04% threshold, and drivers under 21 are caught by 'zero tolerance' at just 0.02% under § 55-10-415. A first, second, or third DUI is a Class A misdemeanor; a fourth or subsequent offense becomes a Class E felony.

The criminal case begins in your county's General Sessions Court, which resolves misdemeanor DUI through to plea or, for felonies, holds a preliminary hearing before binding the case over to Circuit or Criminal Court — the courts of record where jury trials happen. Sentencing runs off Tenn. Code Ann. § 55-10-402, which sets hard, non-suspendable mandatory-minimum jail time on every offense, escalating fines, and revocation periods. Appeals from a conviction go to the Tennessee Court of Criminal Appeals.

Running entirely alongside that is the civil 'implied consent' track under Tenn. Code Ann. § 55-10-406. By driving in Tennessee you've already consented to chemical testing, and refusing it triggers a license suspension handled not by a judge but by the Tennessee Department of Safety and Homeland Security. These two tracks are decoupled: you can beat the criminal charge and still lose your license, or vice versa.

Tennessee overhauled its implied-consent law effective January 1, 2026 (Pub. Ch. enacting HB 1204 / SB 1400). A first refusal of a blood test now carries an 18-month suspension (up from one year) where there's no qualifying prior within 10 years, oral-fluid testing for THC and other drugs is now expressly covered, officers may use reasonable force to obtain a blood draw, and the old 'blood drawn by warrant means no refusal charge' loophole is closed. Any DUI guidance written before 2026 may now be out of date — which is exactly why a quick free call to confirm the current rules matters so much.

In Tennessee, You Can Win Your DUI Case and Still Lose Your License

Here's the trap that catches Tennesseans every week: if you refused the test, the criminal DUI and the license suspension are two separate cases, decided by two different bodies, on two different clocks. The criminal charge is fought in General Sessions or Criminal Court. But the license loss for refusing is handled by the Department of Safety under Tenn. Code Ann. § 55-10-406 — and you have just 10 days from arrest to demand a hearing. People focus on the court date weeks away and never notice the 10-day clock until it's expired. By then the revocation is automatic, even if the criminal charge is later dropped. As of January 1, 2026, a first blood-test refusal means an 18-month suspension. Call 1-844-690-0555 now, free and 24/7, before that clock runs out.

Likely outcomes & penalties

Every Tennessee DUI carries consequences on both tracks. Here's the realistic range under current law — actual outcomes depend on your BAC, your priors within the 10-year window, and whether anyone was hurt.

First Offense (Class A misdemeanor)

48 hours to 11 months 29 days jail — but a hard, non-suspendable 48-hour minimum (7 consecutive days if BAC ≥ 0.20%). Fine $350–$1,500, 1-year license revocation, ignition interlock, DUI school and a MADD Victim Impact Panel.

Second & Third Offense

Second: 45-day minimum, $600–$3,500, 2-year revocation. Third: 120-day minimum, $1,100–$10,000, 3-to-10-year revocation (commonly 6 years). Mandatory interlock throughout; minimum days are served day-for-day.

Refusal (civil, no jail)

A separate license suspension under implied consent: 18 months for a first blood-test refusal with no qualifying prior (effective 1/1/2026), 2 years for a second, 5 years for a third. This applies even if you're never convicted of the DUI itself.

Felony & Aggravated DUI

Fourth offense in 10 years = Class E felony, 150-day minimum served day-for-day, $3,000–$15,000 fine, 8-year revocation. DUI causing serious injury = vehicular assault (Class D); intoxication-based vehicular homicide is a Class B felony (8–30 yrs), and aggravated vehicular homicide can reach Class A (15–60 yrs).

Mistakes to avoid

⚠️

Letting the 10-day implied-consent deadline pass because you assumed the court date weeks away was the only thing that mattered — by then your license revocation for refusal is automatic and can't be undone.

⚠️

Believing that beating or getting your criminal DUI dismissed will automatically restore your license — the two tracks are fully decoupled in Tennessee, and a refusal suspension stands unless you separately contested it within 10 days.

⚠️

Expecting a 'wet reckless' plea-down or judicial diversion like some other states allow — Tennessee explicitly bars judicial diversion for a DUI conviction, and expunction is off the table except a narrow path for a single very old, injury-free offense under the 2026 changes.

⚠️

Driving during your revocation without first obtaining a court-ordered restricted license through ignition interlock — there is no automatic hardship permit in Tennessee, and driving on a revoked license is a fresh crime.

⚠️

Treating the new 2026 rules as if the old law still applies — a first blood-test refusal is now 18 months not 12, oral-fluid testing is covered, officers can use reasonable force to draw blood, and the warrant 'loophole' is closed, so pre-2026 advice can hurt you.

FAQ — DUI Defense in Tennessee

I just got arrested for DUI in Tennessee — what's the very first thing I should do?

Find your arrest paperwork and look for the implied-consent notice. If you refused testing, a 10-day clock to contest your license loss is already running — separate from the criminal court date, which is usually weeks away. Call 1-844-690-0555 now, free and 24/7, to understand both tracks before any deadline passes.

What is this 10-day deadline everyone keeps mentioning?

Under Tenn. Code Ann. § 55-10-406, if you refused a breath, blood, or oral-fluid test, you have just 10 days from arrest to request an administrative hearing with the Department of Safety to fight the license revocation. Miss it and the suspension becomes automatic. Call 1-844-690-0555 to confirm whether this applies to you before the clock runs out.

Can I lose my license even if my DUI charge gets dismissed?

Yes. Tennessee's criminal and license tracks are fully decoupled, so a refusal suspension under implied consent can stand even after the criminal DUI is dropped — unless you contested it within 10 days. It's a brutal surprise for people who 'won' their case. Call 1-844-690-0555 for free information on protecting both.

How much jail time does a first DUI carry in Tennessee?

A first DUI is a Class A misdemeanor with a non-suspendable minimum of 48 hours, up to 11 months 29 days — and a mandatory 7 consecutive days if your BAC was 0.20% or higher. Unlike many states, Tennessee won't let that minimum be fully probated away. Call 1-844-690-0555 to understand your specific exposure.

Can I get a DUI expunged or take a diversion deal in Tennessee?

Almost never. Tennessee bars judicial diversion for a DUI, and for years no DUI conviction could be expunged at all. A narrow 2026 change opened a path only for a single, very old DUI that caused no injury — most convictions still stay on your record permanently. That makes any plea higher-stakes than in 'wet reckless' states. Call 1-844-690-0555 for free information before you agree to anything.

I refused the breathalyzer or blood test — what happens now?

As of January 1, 2026, a first blood-test refusal with no qualifying prior carries an 18-month license suspension (up from one year), a second refusal is 2 years, and a third is 5 years — all civil, with no jail. New rules also cover oral-fluid testing and let officers use reasonable force to draw blood. Call 1-844-690-0555 to learn the current consequences for your situation.

Can I still drive during my revocation?

Only if you petition the court for a restricted license, which generally requires an ignition interlock device under Tenn. Code Ann. § 55-10-417. There's no automatic hardship permit in Tennessee, and driving on a revoked license is a fresh crime. Call 1-844-690-0555 for free information on the restricted-license process.

My teenager got a DUI — is it different for under-21 drivers?

Yes. Tennessee's 'zero tolerance' driving-while-impaired law (§ 55-10-415) catches under-21 drivers at just 0.02% BAC, with a 1-year license suspension and a fine starting at $250. But at 0.08% or more, a young driver can be charged under the much harsher adult DUI statute. Call 1-844-690-0555 to understand which charge applies.

How bad does a second or third DUI get in Tennessee?

A second DUI carries a 45-day minimum and a 2-year revocation, $600–$3,500 in fines; a third jumps to a 120-day minimum and a 3-to-10-year revocation (commonly 6 years), with fines up to $10,000. Priors within the 10-year look-back drive the escalation, and a fourth becomes a Class E felony. Call 1-844-690-0555 for free information on repeat-offense exposure.

I'm not a U.S. citizen — could a Tennessee DUI affect my immigration status?

Immigration consequences are decided under federal law by USCIS and the immigration courts (EOIR), not by the Tennessee court. A single simple DUI usually isn't deportable on its own, but a DUI with aggravators — drugs, a child passenger, injury, or repeat offenses — or a DUI plus another charge can trigger problems. You need Tennessee DUI defense coordinated with immigration counsel before any plea. Call 1-844-690-0555 to get oriented first.
