Underage DUI in Kentucky: Zero Tolerance Law

Kentucky’s Zero Tolerance Law for Underage DUI

Kentucky takes underage drinking and driving seriously. Under the state’s “zero tolerance” law, drivers under 21 can be charged with DUI at a blood alcohol concentration far lower than the standard adult limit. An underage DUI conviction can have lasting consequences that extend into college, career, and beyond. Clark + Harris provides experienced DUI defense for underage drivers in Lexington, Louisville, and throughout Kentucky.

Kentucky’s Zero Tolerance Law — KRS 189A.010

Under KRS 189A.010(1)(c), it is unlawful for any person under 21 to operate or be in physical control of a motor vehicle with a blood alcohol concentration of .02 or higher. This is far below the .08 limit that applies to adult drivers.

The .02 threshold reflects the fact that Kentucky law prohibits drinking under 21 entirely. A .02 BAC can result from a single alcoholic beverage, meaning that underage drivers can be charged with DUI after consuming very small amounts of alcohol.

Penalties for Underage DUI Under KRS 189A.010(11)

When an underage driver is convicted of DUI with a BAC between .02 and .08, specific penalties apply under KRS 189A.010(11)(b):

First Offense: Fine of $100-$500, community service, 30-180 day license suspension, mandatory alcohol and drug education or treatment, $375 service fee.

Second Offense: Fine of $200-$500, community service of 20-40 hours, license suspension of 6 months to 2 years, mandatory alcohol and drug treatment.

Subsequent Offenses: Additional penalties including potential jail time.

If an underage driver’s BAC is .08 or higher, the driver is subject to adult DUI penalties under KRS 189A.010(5) rather than just the zero tolerance provisions.

Impact on College Students

An underage DUI conviction can have devastating consequences for college students attending University of Kentucky, University of Louisville, Western Kentucky University, Eastern Kentucky University, and other Kentucky institutions:

Academic Consequences: Most universities have code of conduct provisions addressing off-campus criminal conduct. DUI convictions can trigger disciplinary proceedings, probation, suspension, or expulsion.

Financial Aid Impact: While DUI alone typically does not affect federal financial aid, drug convictions can. Additionally, loss of scholarships based on criminal conduct is common.

Housing Consequences: On-campus housing agreements often include conduct requirements. DUI convictions can result in loss of housing privileges.

Graduate and Professional School: Applications to graduate schools, medical schools, law schools, and other professional programs require disclosure of criminal convictions. DUI convictions can affect admissions decisions and scholarship consideration.

Employment: Internships, co-op positions, and post-graduation employment opportunities may be affected by DUI convictions, particularly in fields requiring professional licensing, security clearances, or driving.

Impact on Future Career and Licensing

Many professional licensing boards require disclosure of criminal convictions during the application process. An underage DUI conviction can affect licensing for:

Nursing and healthcare professions
Teaching and education
Legal practice
Accounting and financial services
Real estate
Commercial driving (automatic CDL disqualification)
Pilot’s license and aviation

Even when licensing boards do not deny licenses based on DUI convictions, disclosure requirements and additional scrutiny can complicate and delay licensing processes.

Defense Strategies for Underage DUI Cases

The low .02 BAC threshold means that underage DUI cases often turn on small margins in breathalyzer readings. Clark + Harris develops comprehensive defense strategies:

Challenging Breathalyzer Accuracy: Breathalyzer machines have margins of error that can be significant at very low BAC levels. A reading of .02 may actually reflect a true BAC of .01 or even .00. Calibration issues, mouth alcohol, and physiological factors can all affect readings.

Challenging the Stop: Officers must have reasonable suspicion to stop a vehicle. We examine the basis for every stop and move to suppress evidence when stops lack legal foundation.

Challenging Field Sobriety Tests: Underage drivers with low BAC may appear completely sober on field sobriety tests, particularly when BAC is in the .02 to .05 range. We scrutinize test administration and challenge subjective interpretations.

Pretrial Diversion: First-time underage DUI offenders may be eligible for pretrial diversion under KRS 533.250. Successful completion of diversion results in dismissal of charges, preserving the young person’s record.

Alternative Resolutions: We work to negotiate alternative resolutions that minimize long-term consequences. These might include reduction to reckless driving, plea to a non-driving offense, or other creative solutions.

The 10-Year Lookback Period

One positive aspect of Kentucky’s zero tolerance law is that underage DUI convictions are not counted for subsequent DUI enhancement under the 10-year lookback rule. However, the conviction still appears on criminal records and affects collateral consequences.

Other Underage Alcohol Offenses

Beyond underage DUI, we defend against related charges including:

Possession of alcohol by a minor under KRS 244.085
Use of false identification to obtain alcohol
Public intoxication under KRS 222.202
Alcohol intoxication in a public place under KRS 525.100

These offenses often accompany DUI charges and can compound the consequences for young defendants.
