Tennessee DUI Laws

Blood Alcohol Concentration - (BAC) Limit

In Tennessee, as in most other states, a person can be charged with DUI if their Blood Alcohol Concentration (BAC) meets or exceeds the legal limit. The legal BAC limit varies depending on the driver's age and the type of vehicle being operated.

TN BAC Limits by Age and Offense

Standard Drivers (21 years and older) 0.08%+
Commercial Auto and Boat Drivers 0.04%+
Underage Drivers (under 21 years old) 0.02%+
Aggravated Homicide 0.20%+
Aggravated DUI (7 consecutive days in jail) 0.20%+

A person can be charged with a DUI even if their BAC is below the legal limit if their driving is deemed impaired due to the consumption of alcohol or drugs.

Implied Consent Law

“Refusal to Blow”

Refusing a Blood Alcohol test as a driver may have serious consequences under Tennessee’s Implied Consent Law. If a driver refuses to submit to a breath, blood, or urine test, they can face a license suspension and potential ignition interlock requirements.


If the driver has prior DUI convictions or is involved in an accident causing injury or death, the penalties for refusing to blow in TN can be even more severe.

Refusing a chemical test does not guarantee avoiding a DUI charge or conviction. Law enforcement officers will gather other evidence of impairment through observations, field sobriety tests, and witness testimony, which can be used to support a DUI charge in court.


Understanding and complying with the Implied Consent Law can be essential in avoiding additional penalties and complications in a DUI case.

Open Container Law

Tennessee's open container law prohibits DRIVERS ONLY, not passengers, from possessing an open alcoholic beverage container within the passenger area of a motor vehicle while on a public highway or right-of-way.


Violating this law can result in fines and penalties and may also contribute to a DUI charge if the driver is found to be under the influence of alcohol.


This TN law is different than many states' open container laws since it
doesn’t prohibit passengers from having or consuming an open alcoholic beverage.

Zero-Tolerance for Underage Drunk Drivers

Tennessee enforces a zero-tolerance policy for underage drunk drivers, which means that drivers under 21 found with a Blood Alcohol Concentration (BAC) of 0.02% or higher can be charged with a DUI. 


This policy aims to
discourage underage drinking and driving and protect teen drivers and others from impaired driving. Violation of this policy can result in severe penalties, including license suspension, fines, and mandatory alcohol education programs.
