DUI Penalties in Tennessee
Let Our Chattanooga DUI Lawyer Defend You

DUI offenses are not taken lightly in the state of Tennessee. Facing these types of charges puts you at risk of serious and long-lasting penalties.

The Blood Alcohol Content (BAC) limit in Tennessee for a driver 21 or older is .08%. If you are under age 21, the BAC limit is .02% and if found above your legal limit, you may be charged with DUI. In order to determine a driver’s BAC level, there are three types of chemical tests that can be performed. A driver is required to perform one of these chemical tests when arrested for a DUI under the implied consent law. If a driver refuses to submit a test, they may be facing penalties.
