We Fight Tennessee DUIs Like Your Future Depends on It.
Close to 20,000 people were charged with DUI in Tennessee in 2024. But even though DUI charges are common in the Volunteer State, the consequences can be dire.
A first-time DUI in Tennessee carries a mandatory minimum of 48 hours in jail, fines from $350 to $1,500, a one-year driver's license revocation, and mandatory participation in a drug or alcohol treatment program.
A DUI can also impact your driver's license, insurance rates, and even your job.
When you hire Michael & Associates Criminal Defense Attorneys, our goal is simple: Our experienced Tennessee defense attorneys will fight to get your case dismissed or to minimize the consequences as much as possible.
What is a DUI in Tennessee?
Tennessee DUI law prohibits any person from driving or being in physical control of a motor vehicle while under the influence of drugs, alcohol, or any intoxicant that impairs their ability to operate the vehicle safely.
Tennessee courts have interpreted the phrase "physical control" to mean having care, custody, or control of the vehicle, which can include simply sitting in the driver's seat with the keys in your pocket, even if the engine is off.
Typically, the legal standard for intoxication is a blood alcohol concentration (BAC) of 0.08% or higher for drivers ages 21 and over. Commercial drivers are subject to a 0.04% limit, and drivers under 21 may be penalized for a BAC as low as 0.02%.
However, you don't have to fail a breathalyzer test to be arrested and charged with DUI. Tennessee law allows DUI charges even if your BAC is below 0.08%, as long as the police officer can prove that your ability to drive was impaired "to the slightest degree" due to:
- Alcohol
- Controlled substances
- Prescription medications
- Any other intoxicating substance
This means that simply appearing impaired is enough for you to be arrested for DUI, even without chemical or field testing.
Refusing certain chemical testing can result in a separate driver's license revocation under Tennessee's implied-consent law. For certain first-time implied-consent violations, Tennessee increased the driver's license revocation period from one year to 18 months beginning January 1, 2026. The rules depend on the circumstances of the refusal and the driver's prior record.
Oral-Fluid Testing
Tennessee police now have another tool to build a DUI case: oral-fluid testing. These tests use a saliva sample to look for evidence of drugs or other intoxicants in a driver's system, and the results can be used as evidence in court.
But a positive oral-fluid test does not automatically prove that you were impaired or guilty of DUI. Our attorneys can examine how the sample was collected, whether police followed Tennessee law, how the test was handled and analyzed, and whether the results actually support the claim that you were impaired while driving.
Like blood, breath, and field sobriety evidence, oral-fluid test results should be scrutinized rather than simply accepted as proof of intoxication.
DUI Penalties and Consequences in Tennessee
In 2024, 19,923 people were arrested and charged with DUI. Tennessee is considered one of the worst states for drunk driving, with a high rate of alcohol-related traffic fatalities. A significant portion of these fatalities involve drivers with a BAC of 0.15 or higher. In our ranking of states with the strictest DUI enforcement, Tennessee ranked 14th.
Penalties for DUI in Tennessee vary based on prior offenses and any aggravating circumstances.
First Offense
A first offense carries a mandatory minimum of 48 hours in jail — or 7 days if the BAC is 0.15% or higher — as well as 11 months and 29 days of probation, fines ranging from $350 to $1,500, a one-year license revocation, and mandatory participation in an alcohol or drug treatment program.
Second Offense
A second DUI conviction increases the required jail time to at least 45 days. Additionally, you'll pay a fine ranging from $600 to $3,500. Your license could be revoked for two years.
Third Offense
Third-time offenders face a mandatory minimum jail term of 120 consecutive days, with a maximum of 11 months and 29 days in county jail and fines ranging from $1,100 to $10,000. After jail, you're typically placed on probation to complete the remainder of your sentence. Your license will be revoked for six years.
Fourth Offense
A fourth DUI will be charged as a Class E felony. Penalties could include:
- Up to six years in jail with a mandatory minimum sentence of 150 consecutive days served day‑for‑day
- Fines between $3,000 and $15,000
- Driver's license revocation for eight years
Aggravating Factors
Aggravating factors such as a child passenger, elevated BAC, or causing injury or death can elevate charges and consequences, which may include vehicle forfeiture and mandatory ignition interlock installation.
How a Tennessee DUI Can Affect Your Driver's License
Tennessee does not have an Administrative License Revocation (ALR) process like some other states. However, your driver’s license can still be revoked in two key ways:
- If you are convicted of DUI, the Tennessee Department of Safety and Homeland Security will impose a license revocation as part of the sentence.
- If you refuse chemical testing under Tennessee's implied-consent law, you may face a separate driver's license revocation even if you're not ultimately convicted of DUI. For certain first blood-test refusals occurring on or after January 1, 2026, the revocation period is 18 months.
These are separate administrative consequences that can significantly impact your ability to drive, regardless of the outcome of your criminal case.
What to Do If You're Pulled Over in Tennessee
-
Don't agree to take field sobriety tests or a breathalyzer test. Field sobriety and chemical testing can create evidence in a DUI investigation. Before deciding how to respond to a request for testing, understand that Tennessee's implied-consent law can impose separate driver's license consequences for certain refusals.
-
Police can (and will) obtain a court order for a blood draw. If officers obtain a valid warrant or another legal basis authorizes the test, refusing to cooperate does not necessarily prevent them from obtaining a sample. An earlier refusal may also carry separate consequences under Tennessee's implied-consent law.
If you've already submitted to a breath or blood test and it showed you were over the limit, there's no need to panic. Michael & Associates has DWI scientists on staff who are highly skilled at challenging these results.

How to Fight a Tennessee DUI Arrest
At Michael & Associates, we've developed a playbook to challenge DUI arrests successfully.
- Question the evidence: We will question the circumstances of your traffic stop and the validity of any field sobriety testing you agreed to complete. We will also review whether the police report matches any video evidence from the scene.
- Did the officer make a mistake? It's important to remember that you have rights. We will investigate how the arresting officer handled your case and how the evidence was processed.
- Driving conditions: Was the weather bad, or were you attempting to avoid an obstacle in the road? Could something have affected visibility?
- Did the officer smell alcohol? The smell of alcohol isn't enough to indicate intoxication. If you consumed a single drink or someone spilled alcohol on your clothing, you may be better off agreeing to complete a chemical test (but not field sobriety testing).
- Is someone judging your appearance? If you're tired, you could have bloodshot eyes and a disheveled appearance that could be misinterpreted. Slurred speech can also lead to misunderstandings.
- Questioning field test results: If your balance is poor, you were stopped on a hill, or you were taking tests under less-than-ideal conditions, it could impact your results.
