Is 35% Window Tint Legal in Switzerland After the 2026 Law Changes?

No. Swiss traffic regulations, enforced by the Federal Roads Office (FEDRO), prohibit window tints below 70% light transmittance for front side windows and windshields. A 35% tint violates these standards, risking fines up to CHF 100 and mandatory removal.

Key Regulations for 35% Window Tint in Switzerland

  • Light transmittance requirement: Front side windows and windshields must allow at least 70% light transmittance (Art. 31, Traffic Regulation Ordinance). Tints reducing visibility below this threshold are illegal.
  • Medical exemptions: Only vehicles with certified medical waivers (e.g., for photosensitivity) may exceed 70% tint limits, subject to FEDRO approval.
  • Post-2026 enforcement: FEDRO’s 2026 digital compliance checks will use roadside light transmittance meters to detect violations, increasing penalties for non-compliant vehicles.

Swiss cantons (e.g., Zurich, Geneva) conduct random inspections, with repeat offenders facing vehicle impoundment. Aftermarket tints must comply with Swiss standards (SN EN 14500), as non-certified films are inadmissible.
