Refusing a Breathalyzer in Kentucky: Implied Consent...

Understanding Kentucky’s Implied Consent Law

When you are arrested for DUI in Lexington, Louisville, or anywhere in Kentucky, police will likely ask you to submit to chemical testing — breathalyzer, blood, or urine testing — to determine your blood alcohol concentration. What many drivers do not realize is that Kentucky law requires you to submit to such testing under the state’s implied consent law. Refusing testing has significant consequences. Clark + Harris helps DUI clients understand their rights and the implications of chemical test refusal.

Kentucky Implied Consent Law — KRS 189A.103

Kentucky’s implied consent statute, KRS 189A.103, provides that any person who operates or is in physical control of a motor vehicle in Kentucky is “deemed to have given consent” to chemical tests to determine alcohol concentration or the presence of drugs. This “implied consent” applies when:

A police officer has reasonable grounds to believe you are operating or were operating a motor vehicle under the influence
You have been arrested for DUI
The officer requests a chemical test

The officer is entitled to designate which test (breath, blood, or urine) will be administered. You do not have the right to choose the test.

What Constitutes a Refusal?

Under Kentucky law, a “refusal” occurs when you:

Verbally refuse to submit to testing
Physically refuse to cooperate with testing procedures
Fail to provide an adequate breath sample after multiple attempts
Condition your consent on terms not authorized by law (e.g., demanding to speak with an attorney first)
Leave the testing area before testing is completed

Importantly, you have a limited right to contact an attorney before deciding whether to submit to testing. KRS 189A.105(2)(a) provides that you may contact an attorney, but only for a reasonable period of time — typically 10 to 15 minutes. Extended delay may be considered a refusal.

Consequences of Refusing Chemical Testing in Kentucky

Enhanced License Suspension: Under KRS 189A.107, refusal to submit to testing results in mandatory administrative license suspension. The suspension periods for refusal are:

First refusal: 30 to 120 days (the same as a typical first-offense DUI)
Second refusal within 10 years: 12 to 18 months
Third refusal within 10 years: 24 to 36 months
Fourth refusal within 10 years: 60 months

Aggravating Factor at Trial: Under KRS 189A.010(11)(e), refusing a chemical test is an aggravating factor that triggers mandatory minimum jail time if you are convicted of DUI. This means that even if your BAC would have been below .15, refusal itself can result in the same mandatory minimums as having a BAC of .15+.

Evidence of Consciousness of Guilt: The prosecution can introduce evidence of your refusal at trial, arguing to the jury that the refusal reflects consciousness of guilt.

No Opportunity for Reduced Suspension: DUI convictions allow for some flexibility in license reinstatement. Refusal suspensions generally do not.

When Might Refusing Make Sense?

Despite the serious consequences of refusal, there are situations where refusing testing may be a rational choice. These include:

Very High BAC Situations: If you have consumed a significant amount of alcohol and are likely to blow a high BAC, refusal eliminates the most damaging evidence the prosecution would have. A “paper case” (DUI case without chemical test evidence) is generally harder for the prosecution to prove.

Drug-Related DUI: If you have used drugs (prescription or illegal), blood testing can reveal multiple substances and complicate the case significantly. Refusal may limit evidence in some circumstances.

Fourth-Offense DUI Exposure: Because fourth-offense DUI within 10 years is a felony, and because Kentucky’s lookback period is 10 years, defendants with three prior DUIs sometimes refuse to avoid felony conviction.

However, the decision to refuse is complex and should never be made lightly. The best approach is to contact an attorney immediately before making any testing decision.

The Limited Right to Contact an Attorney

Kentucky law provides that you may contact an attorney before deciding whether to submit to chemical testing. Under KRS 189A.105, officers must allow you a reasonable opportunity to contact a lawyer, but the time is limited. If you are unable to reach an attorney within the allotted time, you still must decide whether to submit to testing.

Challenging Refusal-Based Cases

Cases arising from refusal present specific defense opportunities. Clark + Harris defense strategies in refusal cases include:

Challenging Whether a Refusal Occurred: Did the officer give proper warnings? Did you actually refuse, or were you confused? Were your questions interpreted as refusals when they were actually attempts to clarify?

Challenging the Underlying Arrest: If the DUI arrest itself was unlawful, the refusal consequences may not apply.

Challenging the Warnings: Kentucky law requires specific warnings before testing is requested. If warnings were inadequate, the refusal may not count.

Challenging the Evidence Without Chemical Tests: In refusal cases, the prosecution must prove impairment without chemical test results. We challenge field sobriety tests, officer observations, and other evidence.
