No, Swiss traffic regulations do not explicitly prohibit driving with interior lights on, but they mandate that such lighting must not impair visibility or distract other road users, as per Article 31 of the Traffic Ordinance (VRV). The Federal Roads Office (FEDRO) interprets this to mean interior lights should be dimmed or off in low-visibility conditions or when approaching other vehicles.
Key Regulations for Driving With Interior Lights On in Switzerland
- Visibility and Distraction Clause (Art. 31 VRV): Interior lighting must not obstruct the driver’s view or blind other motorists, particularly during nighttime or in tunnels.
- Tunnel and Low-Light Provisions (Art. 45 VRV): In tunnels or under poor lighting, interior lights must be off to prevent glare and ensure compliance with safety standards enforced by FEDRO.
- Local Enforcement Discretion: Cantonal traffic police (e.g., Zurich’s Verkehrspolizei) may issue fines up to CHF 100 if interior lights are deemed to compromise road safety, aligning with 2026 updates to the Strassenverkehrsgesetz (SVG).
Swiss law prioritizes unobstructed visibility and minimal distraction. While no outright ban exists, drivers bear liability for any impairment caused by improper interior lighting. The 2026 amendments to the SVG reinforce this stance, emphasizing electronic device and auxiliary lighting restrictions.
