No, 50% window tint is not universally legal in Belgium. Belgian law mandates front-side windows must allow ≥70% light transmittance, while rear windows may have darker tints if the vehicle has side mirrors on both sides. Non-compliance risks fines up to €137.50 and mandatory removal. The 2026 EU Vehicle Lighting Regulation may further tighten these standards.
Key Regulations for 50% Window Tint in Belgium
- Front-side windows (driver/passenger): Must transmit ≥70% of light (VL ≥70%). 50% tint violates this, as it typically blocks 50% of light (VL ≤50%).
- Rear windows: Permitted if the vehicle has exterior mirrors on both sides, but local authorities (e.g., Service Public Fédéral Mobilité) may impose additional restrictions.
- Medical exemptions: Rarely granted via SPF Santé Publique with certified documentation; standard 50% tint does not qualify.
