Washington Window Tinting Laws – Full Guide for Car Owners
Key Takeaways
- Washington tint laws regulate film based on VLT percentage, window position, and vehicle type.
- Sedans must have at least 24% VLT on front side windows, while SUVs and vans allow darker tints on rear glass.
- Reflective window film is restricted across all vehicle types; mirrored films are not permitted.
- Additional rules require dual mirrors, manufacturer-certified film, and compliance stickers for legal installations.
What Is VLT In Window Tinting?
Visible Light Transmission (VLT) is the percentage of visible light allowed through a tinted film. The lower the VLT, the darker the window coating appears. Washington’s law mandates different VLT minimums by window position. Choosing the wrong shade could make your automotive tinting illegal.
Window Tint Darkness In Washington
Washington regulates window tint darkness based on three key factors: VLT percentage, window position, and vehicle type. Different rules apply to windshields, side windows, and rear glass. Sedans follow stricter standards than SUVs or vans. The next sections explain these differences clearly.
Tint Rules For Sedans
Sedans must meet stricter VLT limits, and legal installation requires certified UV protection film:
- Windshield: Top 6 inches, non-reflective
- Front side windows: Minimum 24% VLT
- Backside windows and rear windshield: Any darkness
Tint Rules For SUVs And Vans
SUVs and vans follow slightly different rules, allowing drivers to install ceramic or carbon film for safer heat control:
- Windshield: Top 6 inches, non-reflective
- Front side windows: Minimum 24% VLT
- Rear side windows and rear windshield: No limit on darkness
Window Tint Reflection In Washington
Washington limits how much window film can reflect light. Legal reflectivity depends on window location and vehicle classification. Because reflective materials increase glare and reduce safety, the law sets specific rules for sedans, SUVs, and vans.
Tint Reflectivity Rules For Sedans
To meet legal requirements, sedans must use non-reflective window film and avoid metalized or mirrored tint that causes glare:
- Front side windows: No mirrored reflection
- Backside windows: Same restriction
Tint Reflectivity Rules For SUVs And Vans
SUVs and vans follow the same reflectivity rules, making nano-ceramic or IR-blocking films the best legal options:
- Front and rear side windows: No extra reflectivity
- Rear windshield: Reflectivity must match standard glass
Other Window Tint Laws In Washington State
In addition to VLT and reflectivity, legal tint in Washington includes several important requirements that affect installation and inspection:
- Red, yellow, and amber tints are not allowed
- Dual side mirrors are required if the rear glass is tinted
- Manufacturer-certified film is mandatory
- A compliance sticker is needed on the driver's side window
- Medical exemptions accepted with paperwork
Notes And Legal Reminders
To stay compliant with Washington’s tint laws, vehicle owners must verify the VLT rating before applying any film. Using only OEM-approved products ensures legal visibility levels. If darker tints are medically required, drivers must carry official exemption documentation at all times.
