Ignition Interlock Laws in Kentucky

Lifesafer Ignition Interlock Kentucky
The state of Kentucky uses two different means of convicting people for DUI:

  1. If you operate a vehicle while being impaired due to alcohol or other drugs
  2. If your blood alcohol content (BAC) is .08 or higher, even if you do not show signs of being impaired

Driving under the influence (DUI) in Kentucky may result in a court order for an ignition interlock device (IID). For those under the age of 21, any trace of alcohol can warrant an arrest, as Kentucky has a zero-tolerance policy for underage drinking and driving.
