KRS 189.040: Vehicle Lighting Requirements in Kentucky

What Is KRS 189.040?

KRS 189.040 establishes Kentucky’s vehicle lighting requirements. Headlights, taillights, brake lights, and turn signals must all function properly. While these are minor violations, they’re frequently used as pretexts for traffic stops in Lexington and Louisville that lead to more serious charges.

What the Statute Requires

Two functioning headlights, properly aimed
Functioning taillights visible from required distances
Brake lights that activate when the brake is applied
Turn signals that operate properly
Headlights on between sunset and sunrise, and during low visibility

Penalties Under KRS 189.040

Violation: Fines
No license points typically
“Fix-it” tickets often available with proof of repair

The Pretextual Stop Problem

Many DUI arrests, drug seizures, and weapons cases begin with a stop for a defective taillight. If your case involves serious charges that arose from a lighting violation stop, the legality of that stop becomes critically important.

Defenses Available

Light was actually functioning
Officer’s observations were inaccurate
The defect didn’t justify the stop
Repaired before court (often dismissed)
