Yes, Kentucky Revised Statutes (KRS 189.020) do not explicitly prohibit driving with interior lights on, but the Kentucky State Police emphasize that such lighting must not impair visibility or distract other drivers. Local ordinances in Louisville Metro and Lexington-Fayette may impose additional restrictions, particularly during 2026 traffic safety reviews.
Key Regulations for Driving With Interior Lights On in Kentucky
- Visibility Standard (KRS 189.290): Interior lights must not obstruct the driver’s view or create glare that hinders other motorists’ ability to perceive traffic signals or pedestrians.
- Distraction Mitigation (KRS 189.950): The Kentucky Transportation Cabinet’s 2026 safety audit flags excessive interior lighting as a potential distraction, aligning with national NHTSA guidelines on “in-vehicle distractions.”
- Local Ordinances: Louisville Metro Code §150.102 and Lexington-Fayette Urban County Code §17.20 require drivers to ensure interior lighting does not violate “reasonable visibility” standards, with enforcement discretion left to local law enforcement.
Failure to comply may result in citations under “unsafe vehicle equipment” violations, particularly if the lighting contributes to a traffic incident. The Kentucky State Police recommend using interior lights sparingly and only when necessary to avoid secondary enforcement actions.
