No, 35% window tint is illegal in Washington under state regulations. The Washington State Patrol enforces a 24% light transmittance minimum for front side windows, while rear windows may use darker tints if the vehicle has side mirrors. Non-compliance risks citations and mandatory tint removal.
Key Regulations for 35% Window Tint in Washington
- Front Side Windows: Must allow at least 24% light transmittance; 35% fails this requirement. Violations result in fines up to $250.
- Rear Side Windows: Permitted up to 24% only if the vehicle has dual side mirrors. Otherwise, 35% remains prohibited.
- Windshield: Non-reflective tint is allowed only above the AS-1 line (typically the top 4 inches). Any tint below this line is illegal.
Local jurisdictions, including Seattle and Spokane, align with state standards but may impose additional enforcement. The 2026 Washington State Patrol compliance review may tighten penalties for non-compliant tint installations. Medical exemptions exist but require prior approval from the Department of Licensing. Always verify tint specifications with certified installers to avoid legal exposure.
