The Tennessee Implied Consent law states that if you are arrested for suspicion of DUI, you are required to give a blood or breath sample to determine you blood alcohol content. You have a right to refused implied consent. However, if you refuse to give blood or breath under the Tennessee Implied Consent law, you may lose you license for a year or more. The length of loss of license depends on the numbered DUI offense and whether you have ever been convicted of vehicular assault or vehicular homicide. Additionally, a violation of the Tennessee Implied Consent law is not a criminal offense. It is a civil petition, which carries only a loss of license. A violation of the Tennessee Implied Consent law is an A misdemeanor only if you refuse to give blood or breath and you are currently driving while your license is revoked for a prior DUI. If you are charged with a violation of the Tennessee implied consent law, make sure you hire an attorney that can help walk you through the process.
