Washington State Window Tinting Laws for Automotive Windows

Washington State has specific laws governing the use of window tinting on vehicles. The regulations apply to all cars, trucks, and other motor vehicles operated on public roads in the state. Failure to comply with these regulations may result in fines or other penalties.

The following are the window tinting laws for automotive windows in Washington State:

  • Windshield: Tinting is allowed on the top 6 inches of the windshield, or down to the AS-1 line, whichever comes first. The AS-1 line is the marking on the windshield that indicates the maximum allowable tinting.
  • Front side windows: The front side windows must allow at least 24% of light to pass through. This means that the tinting cannot be darker than 24% VLT (Visible Light Transmission).
  • Back side windows and rear window: The back side windows and rear window can be tinted as dark as the driver wants, as long as the vehicle has side mirrors that provide a view behind the vehicle.
  • Medical exemptions: Drivers with a medical condition that requires them to limit their exposure to sunlight may be exempt from the above requirements. To qualify for an exemption, the driver must have a medical authorization form signed by a licensed physician.
  • Law enforcement exemptions: Law enforcement vehicles may have darker tinting on the front side windows, back side windows, and rear window.
  • Penalties for non-compliance: Violating Washington State's window tinting laws may result in a fine of up to $250. Repeat offenders may face steeper fines or other penalties.

It's important to note that these laws apply to all vehicles, including those that are registered in other states but are driven in Washington. Additionally, window tinting laws may vary by city or county, so it's a good idea to check with your local law enforcement agency to make sure you're in compliance.
