Kentucky DUI suspension periods are based on the offense. After serving a required portion of the suspension, eligible drivers may apply for an ignition interlock license.

An Ignition Interlock Device (IID) connects a vehicle or motorcycle's ignition system to a breath alcohol analyzer. The device prevents the vehicle from starting if the driver’s breath alcohol concentration is over 0.02.

• Drivers apply directly to KYTC using the Ignition Interlock Application, TC 94-175.
• KYTC is the monitoring authority for program participants.
• The program is available to DUI offenders who meet program requirements.
• To qualify for a possible reduction in suspension time, participants must follow all program requirements and maintain 90 to 120 consecutive days of sober driving during their incentive period.

To qualify for a possible reduction of suspension time, participants must be violation-free for 90 or 120 consecutive days, based on their offense. Violating one (or more) of the following violations will result in the consecutive counting of days to start over.

• Failure to take any random breath alcohol test unless a digital image review confirms that a driver did not occupy the motor vehicle or motorcycle at the time of the missed test.
• Failure to pass any random retest with a breath alcohol level of 0.02 or lower unless a subsequent test performed within 10 minutes registers a breath alcohol concentration lower than 0.02 and the digital image confirms the same person provided both samples.
• Failure of the person or their designee to appear at the ignition interlock device provider when required for maintenance, repair, calibration, monitoring, inspection, or replacement of the device.
• Failure to pay statutorily required fees (KRS 89A.340.).
• Tampering with an installed ignition interlock device with the intent of rendering it defective.
• Altering, concealing, hiding, or attempting to alter, conceal, or hide the person's identity from the ignition interlock device's camera while providing a breath sample.

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 the 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 Regional Office to:

• Have their signature notarized on the official waiver form issued by Tennessee
• 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 the vehicle.
