Kentucky DUI Laws 2026

Kentucky's DUI laws have gone through significant changes in recent years, and many online sources still cite outdated penalty structures. If you are facing a first-offense DUI in 2026, here is what the current law actually requires — based on KRS 189A.010 as amended by Senate Bill 85.

The SB 85 Overhaul: What Changed

Senate Bill 85 restructured Kentucky's DUI penalty framework in several important ways. Many legal websites and older attorney articles still reference the pre-SB 85 system, which creates real confusion for drivers trying to understand their situation. The key changes:

License suspension is now a static six months. The older system gave judges discretion to impose a 30-to-120-day suspension for a first offense. Under the current law, the Kentucky Transportation Cabinet imposes a flat six-month administrative suspension upon conviction. Judges no longer control the suspension length.

The DUI service fee increased to $425. The mandatory service fee under KRS 189A.050 was permanently raised by $50 (from $375 to $425) to fund the state's ignition interlock administration program. Any source citing $375 is working from outdated law.

The Kentucky Ignition Interlock Program replaced unconditional restoration. Drivers can no longer simply wait out a suspension and get their license back. The current framework channels first-offense drivers into the KIIP, where they can earn a reduced suspension (four months instead of six) by maintaining 90 consecutive days of violation-free driving with an interlock device installed.

Current First-Offense Penalties Under KRS 189A.010

For a standard, non-aggravated first-offense DUI in 2026:

Criminal penalties (District Court):

• Fine: $200 to $500
• Jail: 48 hours to 30 days (community labor available as a substitute)
• Mandatory $425 DUI service fee (KRS 189A.050)
• Court costs: $150 to $200 (varies by county)
• 90-day mandatory substance abuse education through a CHFS-certified provider

Administrative penalties (KYTC):

• Six-month license suspension
• Eligible for restricted driving through KIIP (ignition interlock)
• $40 reinstatement fee at a KYTC Driver Licensing Regional Office
• Written and vision retesting if suspension exceeds one year

Aggravating Circumstances: The Enhanced Track

KRS 189A.010(11) lists six aggravating factors that double the mandatory minimum jail sentence to four days served day-for-day, with no option for community labor, probation, or suspension:

1. BAC of 0.15% or higher
2. Refusing the chemical test
3. Exceeding the speed limit by 30+ mph
4. Driving the wrong way on a limited-access highway
5. Causing an accident resulting in death or serious physical injury
6. Transporting a passenger under 12 years old

The presence of a single aggravator triggers the enhanced track. Multiple aggravators do not stack additional mandatory days for a first offense, but they influence the judge's sentencing decisions within the 4-to-30-day range.

The Ten-Year Lookback Window

Kentucky determines whether a DUI charge is a first, second, or subsequent offense based on a ten-year lookback period. The lookback counts from the dates of the prior offenses, not the dates of the resulting convictions. A DUI arrest in 2016 followed by a conviction in 2017 counts from 2016 for lookback purposes.

A second offense within the ten-year window elevates the charge to a Class A misdemeanor with substantially harsher penalties. A fourth offense becomes a Class D felony with potential prison time of one to five years.

Diversion Availability in 2026

Kentucky's statewide misdemeanor diversion rules continue to exclude DUI charges. Standard diversion under Rules of Criminal Procedure 1001 and 1002, and the Behavioral Health Conditional Dismissal Program, both explicitly bar DUI offenses.

The only available diversion pathways are localized county-level programs. The most established is the Jefferson County (Louisville) DUI First Offenders Diversion Program, which requires application within 45 days of arraignment, a guilty plea, a BAC below 0.15%, no prior criminal record, and completion of 77 hours of community service across two phases. Not all counties offer any DUI diversion program — Fayette County (Lexington), for example, categorically excludes DUI from all diversion eligibility.

What to Watch: Pending Legislation

Legislative sessions in Frankfort regularly introduce bills that would modify DUI penalties, expand or restrict diversion eligibility, or change the interlock program requirements. If you are currently navigating a DUI case, confirm the specific penalty provisions with the current text of KRS 189A.010 through the Kentucky Legislative Research Commission, rather than relying on summary articles that may not reflect recent amendments.
