Chemical Test Refusal
Tennessee is an implied consent state meaning that drivers are required to take a chemical test if asked by a law enforcement officer. This chemical test will determine a person’s blood alcohol levels or BAC. If refused, an offender will suffer from an automatic license suspension with punishments that can increase with each offense or degree of the accident.
1st offense: 1 year
2nd offense: 2 years
1st offense/crash causing injury: 2 years
1st offense/ crash causing death: 5 years
Any driver guilty of a DUI will be required to install an ignition interlock device in their vehicle in order to be able to drive with a license suspension. The costs associated with this device will be at the responsability of the offender.
A DUI conviction will stay on a person’s record for 10 years in the state of Tennessee.
If you are convicted of driving under the influence under the age of 21, you can receive a DUI charge even if your blood alcohol levels are below the legal limit. A minor found drinking and driving to any degree will be penalized with a year license suspension, a fine of $250 and community service hours ordered by the court.
