Kentucky DUI Penalties by Offense

Driving under the influence (DUI) is one of the most commonly charged offenses in Kentucky. Under KRS 189A.010, penalties escalate significantly with each subsequent offense within a ten-year look-back period. Understanding the penalties you face — and the defenses available — is critical. Clark + Harris, PLLC defends DUI cases throughout Lexington, Louisville, and all of Kentucky.

First-Offense DUI

A first DUI in Kentucky is a Class B misdemeanor. Penalties include 48 hours to 30 days in jail (mandatory minimum 48 hours, or 48 hours of community service), fines of $200 to $500, 30 to 120 day license suspension, mandatory substance abuse treatment (90-day program), and a mandatory ignition interlock device for 6 months upon license reinstatement. Aggravating circumstances — BAC of .15 or higher, excessive speed, accident, minor in the vehicle, or refusal of testing — increase the mandatory minimum jail time to 4 days.

Second-Offense DUI

A second DUI within ten years remains a misdemeanor but carries substantially harsher penalties: 7 days to 6 months in jail (mandatory minimum 7 days, increased to 14 days with aggravating circumstances), fines of $350 to $500, 12 to 18 month license suspension, mandatory substance abuse treatment, community service, and a mandatory ignition interlock device for 12 months. A second offense also requires attendance at a victim impact program.

Third-Offense DUI

A third DUI within ten years is a Class A misdemeanor with penalties including 30 days to 12 months in jail (mandatory minimum 30 days, increased to 60 days with aggravating circumstances), fines of $500 to $1,000, 24 to 36 month license suspension, mandatory substance abuse treatment, community service, and a mandatory ignition interlock device for 30 months. A third offense substantially limits plea bargaining options and typically results in significant jail time.

Fourth-Offense DUI (Felony)

A fourth DUI within ten years is a Class D felony — the most serious DUI classification. Penalties include 1 to 5 years in state prison (mandatory minimum 120 days), fines of $1,000 to $10,000, 60-month license suspension, mandatory substance abuse treatment, and a mandatory ignition interlock device for 60 months. As a felony conviction, a fourth DUI also results in loss of voting rights (until restored), loss of the right to possess firearms, and a permanent felony record.

Aggravating Circumstances

Under KRS 189A.010(11), aggravating circumstances that increase mandatory minimum penalties include: BAC of .15 or higher, operating a motor vehicle 30+ mph over the speed limit, driving the wrong way on a limited-access highway, causing an accident resulting in death or serious injury, refusing to submit to testing, and transporting a passenger under 12 years old.

DUI Defenses

Every DUI case has potential defenses. We challenge the legality of the traffic stop (was there reasonable suspicion?), the administration of field sobriety tests (were they conducted according to NHTSA standards?), the accuracy of breathalyzer or blood testing (was the device properly calibrated and maintained?), and whether proper procedures were followed at every stage. Constitutional violations can lead to evidence suppression and case dismissal.

How Kentucky Traffic Offenses Escalate Beyond Simple Tickets

Many traffic charges in Kentucky start as what seems like a routine stop but quickly escalate. A speeding ticket becomes reckless driving. A missed court date becomes a failure to appear warrant. A suspended license you didn’t know about becomes a criminal charge. And a DUI with an accident becomes a felony. Understanding where your specific charge falls on the severity spectrum — and what it can escalate into — is essential for making smart decisions about how to handle it.

The Points System and License Consequences

Kentucky uses a 12-point system for traffic violations. Accumulating 12 or more points within a two-year period results in automatic license suspension. Common point values: reckless driving (4 points), speeding 26+ over the limit (6 points), following too closely (3 points), improper passing (4 points). For CDL holders, the consequences are even more severe — certain violations trigger CDL disqualification regardless of point totals. A single serious traffic violation can end a commercial driving career.

Why Paying the Fine Isn’t Always the Smart Move

Insurance premium increases: A single moving violation can increase your insurance premiums by 20-40% for three to five years. On a $2,000/year policy, that’s $1,200-4,000 in additional costs — far more than an attorney’s fee to fight the ticket.

CDL implications: Commercial drivers cannot simply pay tickets and move on. Even minor violations can trigger CDL consequences, employment termination, and career damage.

Criminal record: Some traffic offenses — reckless driving, DUI, hit-and-run, driving on a suspended license — are criminal charges that create a permanent record.
