Yes, Interior lights are permitted in South Korea if they do not impair the driver’s vision or distract other road users, per the Road Traffic Act enforced by the Ministry of Land, Infrastructure and Transport (MOLIT). While not explicitly banned, excessive brightness or improper use may lead to penalties under Article 44 (Obstruction of Visibility) or Article 50 (Disturbance to Other Drivers).
Key Regulations for Driving With Interior Lights On in South Korea
- Visibility Obstruction (Article 44, Road Traffic Act): Interior lights must not hinder the driver’s view of the road or surrounding traffic. Courts have upheld fines for lights deemed “excessively bright” or positioned to reflect off the windshield.
- Distraction to Other Drivers (Article 50): Lights visible from outside the vehicle, such as dome lights or footwell illumination, may be deemed a traffic hazard if they cause glare or draw attention away from the road. Local traffic police in Seoul and Busan have cited drivers for such violations during nighttime patrols.
- 2026 Compliance Shifts: MOLIT’s upcoming amendments to the Road Traffic Act will introduce stricter guidelines on interior lighting, aligning with international standards. Vehicles with aftermarket LED strips or colored lighting may face mandatory dimming or removal if deemed non-compliant.
Local ordinances in metropolitan areas further restrict “decorative” lighting, with police empowered to issue on-the-spot fines (₩30,000–₩50,000) for violations. Always ensure interior lights are dimmed or shielded when driving at night.
