Is 15% Window Tint Legal in Washington After the 2026 Policy Reforms?

No. Washington State prohibits 15% window tint as it violates visibility standards under RCW 46.37.055, enforced by the Department of Licensing. Local jurisdictions like Seattle and Spokane may impose additional penalties, including fines up to $250 for non-compliance. The 2026 legislative session may introduce stricter enforcement mechanisms.
