Kentucky Ignition Interlock Program (KIIP)

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​The passing of Senate Bill 85 on July 1, 2020, introduced significant changes to the DUI and ignition interlock laws. Now, the Kentucky Transportation Cabinet delivers a fixed suspension period based on the offense. After serving a specified portion of the suspension period, offenders can apply for an ignition interlock license. Once suspended, offenders may apply for an ignition interlock device​. If approved they can operate the approved vehicle(s) equipped with the device for the allowed timeframe. To view more information regarding DUI laws, please click here.​


An Ignition Interlock Device (IID) is a device certified by the Kentucky Transportation Cabinet (KYTC) that connects a motor vehicle ignition system or motorcycle ignition system to a breath-alcohol analyzer. This device will prevent a motor vehicle ignition or motorcycle ignition from starting and operating if a driver's breath alcohol concentration exceeds 0.02, as measured by the device.​


  • Under the new program, individuals will no longer apply to the court for interlock privileges but will apply directly to KYTC using the Ignition Interlock Application, TC 94-175. Additionally, KYTC is now the monitoring authority for program participants.

  • Before SB 85, the court system denied DUI 1st offenders (with non-aggravating circumstances) access to the program. As of July 1, 2020, the KIIP is available to all drunk driving offenders.

  • Drivers who apply and are approved in the KIIP are eligible for a possible reduction of their license suspension period.​

  • ​The ignition interlock program is compliance-based, meaning offenders will have to complete a 90-120 consecutive day period of driving sober within their incentive period to be eligible for a possible reduction of their suspension time.​​​


The Court will report the conviction or suspension to KYTC. Note: This can take a couple of days. ​A letter of Withdrawal or Suspension will be sent.​

    When a driver resides in Kentucky but has the ignition interlock device as a reinstatement requirement in Tennessee, the Tennessee Department of Safety offers a waiver for the driver. When this occurs, KYTC can sign for TN to waive the TN IID requirement. If KYTC does not agree to sign the waiver, the driver must comply with the reinstatement requirement before the hold will be lifted in TN. 

    TN judges are aware that the Department offers a waiver when the driver meets specific criteria as TN statute specifies. Tennessee imposes both a one-year hard suspension (365 consecutive days) and a one-year IID requirement; the waiver only waives the one-year IID requirement.

    If a driver has a Tennessee waiver, they will need to visit a Driver Licensing Regional office and 
    • Have their signature notarized on the official waiver form issued by Tennesse

    • Apply for Kentucky Ignition Interlock Program (KIIP); and

    • Provide proof of KY Insurance, registration, authorization to install the IID device, make, model and VIN of vehicle.
