No, Washington state prohibits 50% window tint as it fails to meet the 27% light transmittance requirement for front side windows under RCW 46.37.300. Law enforcement may issue citations, and local jurisdictions like Seattle or Spokane enforce this strictly.
Key Regulations for 50% Window Tint in Washington
- Front side windows must allow 27% or more light transmittance; 50% tint violates this threshold.
- Windshield tinting is banned except for a non-reflective strip above the AS-1 line.
- Rear windows may be tinted to 20%, but front windows require compliance with state minimums.
Washington’s 2026 regulatory review may tighten enforcement, aligning with federal safety standards. Local authorities, such as the Washington State Patrol, conduct roadside inspections, and violations incur fines up to $250. Medical exemptions exist but require prior approval from the Department of Licensing.
Aftermarket tints must bear a manufacturer’s label certifying compliance with FMVSS 205. Vehicles with illegal tint may fail inspection at state-approved stations. Out-of-state vehicles must adhere to Washington’s standards within 30 days of residency. Non-compliance risks penalties, including mandatory tint removal.
