Yes, driving with interior lights on is legal in Denmark, provided they do not impair the driver’s vision or distract other road users. The Danish Road Traffic Act (Færdselsloven) does not explicitly prohibit interior lighting, but Section 5 stipulates that vehicle equipment must not obstruct visibility or create hazardous conditions. Municipal traffic authorities and the Danish Road Directorate (Vejdirektoratet) enforce compliance, particularly in urban areas where light pollution concerns are rising. A 2026 amendment to the Traffic Ordinance (Færdselsforordningen) introduces stricter guidelines on non-essential lighting, reflecting EU-wide efforts to reduce distractions.
Key Regulations for Driving With Interior Lights On in Denmark
- Visibility Clause (Section 5, Færdselsloven): Interior lights must not interfere with the driver’s ability to observe traffic, mirrors, or road signs. Excessive brightness or misdirected illumination may be deemed a violation.
- Distraction Standard (2026 Amendment): Non-essential lighting, including interior lights, cannot divert attention from driving. Police may issue fines if lights are deemed to create a “hazardous visual environment.”
- Local Enforcement (Vejdirektoratet & Municipal Authorities): Copenhagen and Aarhus have supplementary guidelines, particularly in pedestrian zones, where interior lights may be restricted during nighttime hours to mitigate light pollution.
Violations are typically classified as minor traffic offenses, punishable by fines up to DKK 1,000 (approx. €134). Courts consider case-specific factors, such as time of day and ambient light conditions, when assessing liability. Vehicles with aftermarket lighting modifications must ensure compliance with EU vehicle lighting regulations (UNECE R48).
