What Factors Turn a Standard DUI Into a Felony Charge

Evan Taylor Law Offices Sept. 4, 2026

A DUI charge is a serious matter. Finding out that it may be treated as a felony can bring a new set of concerns about what happens next. In Kentucky, a fourth or subsequent DUI offense within a 10-year period is classified as a Class D felony. Other circumstances can increase DUI penalties without automatically making the DUI itself a felony. Understanding what changes the charge - and what does not - can give you a clearer picture of what you are facing. 

At Evan Taylor Law Offices, we help people in Owensboro understand why a DUI charge has become more serious and what the prosecution must prove. We can review your prior record, the circumstances surrounding the current charge, test results, and other evidence to determine what issues may affect your defense. 

When does a Kentucky DUI Become a Felony?

Under Kentucky's DUI law, a fourth or subsequent qualifying DUI offense within a 10-year period is a Class D felony. A first, second, or third DUI within that period carries progressively greater penalties, but those offenses are not classified as felony DUI under this provision. 

For the 10-year period, Kentucky looks at the dates of prior DUI convictions. Some DUI convictions from other states or jurisdictions can also count. This means your prior record can change the seriousness of the current case. If prosecutors are treating your DUI as a felony based on earlier convictions, the dates and nature of those convictions matter. 

How Prior DUI Convictions Affect Your Current Charge

Prior DUI convictions can increase both the penalties and, eventually, the classification of a new DUI charge. The fourth qualifying offense within 10 years crosses the line from the misdemeanor penalties that apply to earlier offenses into a Class D felony. 

If prosecutors rely on prior convictions to increase the current charge, those convictions must be established. Kentucky law provides that a certified copy of a prior conviction can serve as proof. 

A conviction from outside Kentucky should not simply be dismissed as irrelevant. Kentucky law allows certain DUI or impaired-driving convictions from other states and jurisdictions to count as prior offenses. We can examine the convictions used against you in your DUI defense in Kentucky

Aggravating Circumstances Can Increase the Penalties

Kentucky also identifies aggravating circumstances that can increase the minimum jail time for a DUI. An aggravating circumstance, however, is not the same thing as a factor that automatically converts the DUI into a felony. 

Under Kentucky law, aggravating circumstances include: 

  • Driving more than 30 mph over the speed limit.

  • Driving the wrong way on a limited-access highway.

  • Causing an accident resulting in death or serious physical injury.

  • Having a qualifying blood or breath alcohol concentration of 0.15 or higher.

  • Refusing a requested breath test in circumstances covered by the statute, except as an aggravating circumstance for a first offense.

  • Driving with a passenger under age 12.

The distinction between an aggravated DUI and a felony DUI is important. An aggravating circumstance can increase the minimum period of incarceration without changing a first, second, or third DUI into a felony under the repeat-offense provision. 

Does a High BAC Automatically Make a DUI a Felony?

No. A high blood or breath alcohol concentration does not, by itself, make a Kentucky DUI a felony. A qualifying alcohol concentration of 0.15 or higher is an aggravating circumstance under Kentucky law. That means it can increase the minimum jail time that applies if you are convicted. 

In your case, a high BAC result can make the charge appear more serious, but “aggravated” and “felony” describe different legal issues. Your prior DUI history remains central to whether the DUI itself qualifies as a felony under Kentucky's repeat-offense rule. 

What If the DUI Involved Serious Injury or Death?

A DUI-related crash that causes death or serious physical injury is an aggravating circumstance under Kentucky's DUI statute. It can therefore increase the minimum jail time associated with a DUI conviction. 

It does not follow, however, that every first DUI involving serious injury or death automatically becomes a felony DUI under the fourth-offense rule. A serious crash may involve additional legal issues or charges that must be evaluated separately based on the facts and applicable law. 

If your DUI charge followed a serious collision, the distinction matters. We can examine how the crash occurred, the evidence of impairment, and the specific charges filed, rather than assuming that every allegation carries the same legal consequences. 

Why Your DUI History Needs a Close Look

When prior offenses can change a current DUI into a felony, simply counting every DUI that has ever appeared on your record is not enough. Kentucky uses a 10-year period for the repeat-offense provision and specifies what prior convictions can count. 

The timing can make a significant difference. Kentucky measures the 10-year period using the dates on which the prior offenses occurred when those offenses resulted in convictions. 

Prior convictions from another jurisdiction can also matter if they fall within the categories recognized by Kentucky law. Reviewing the actual record can establish which convictions prosecutors may rely on and whether the current charge qualifies for felony treatment.
