What are Tennessee’s laws on underage drinking and driving?

On Behalf of | Nov 18, 2025 | CRIMINAL LAW - Drunk Driving

Tennessee enforces strict laws for underage drinking and driving. If you are under 21 and have alcohol in your system while driving, you could face serious penalties that affect your freedom and future. Knowing how these laws work helps you understand the risks before getting behind the wheel.

Zero tolerance for underage drivers

State law follows a zero-tolerance rule for drivers under 21. If your blood alcohol concentration (BAC) reaches 0.02% or higher, officers can charge you with driving under the influence (DUI). This lower limit compared to the adult threshold of 0.08% shows the state’s firm stance against drinking and driving among young drivers. If your BAC is 0.08% or higher, or if you show signs of impairment, you can face the same penalties as an adult DUI offender.

Penalties for underage DUI

A conviction for an underage DUI offense in Tennessee can lead to a one-year driver’s license suspension, a fine of up to $250, and community service. For drivers ages 18 to 20, the offense is a Class A misdemeanor, which may also bring possible jail time depending on the court’s decision. The penalties grow harsher if an accident occurs or your BAC is higher.

Consequences beyond the courtroom

An underage DUI does more than cost you money or driving privileges. Colleges, employers, and insurance companies often review criminal records. A DUI on your record can affect scholarships, job offers, and insurance rates for years. These long-term effects make the offense much more than a temporary setback.

Making responsible choices

The best way to avoid these penalties is simple: do not drink if you are under 21 and never drive after consuming alcohol. If you attend a party where alcohol is served, plan ahead for a sober ride home or use a rideshare service. Responsible decisions today protect your safety and your future.
