Why Compliance with Washington Tint Laws Matters

Driving in Washington means facing both strong sunlight in the summer and poor visibility during rainy or foggy days. Window tint can help block harsh light, reduce glare, and keep your car cooler.

Legal tint keeps me safer, stress-free, and on the road with confidence.


What Changed in Washington Tinting Law 2025?

Washington’s tint laws have remained mostly the same, but enforcement has become more strict in 2025. Police officers and inspectors now use newer digital tint meters to check Visible Light Transmission (VLT) levels more accurately.

Officers are now making sure that all windows meet the legal minimum of 24% VLT, especially for sedans. Any film that makes windows too dark can lead to a citation. Drivers are also reminded that tint rules apply to both new and older vehicles, and updated inspections will catch non-compliant tint. Even vehicles that passed in the past could fail now if the tint no longer meets current enforcement standards.

Window Tinting Laws in Washington

Washington’s window tint laws are based on Visible Light Transmission (VLT), which measures how much light must pass through a tinted window. These laws are designed to maintain driver visibility and road safety. Rules differ depending on whether your vehicle is a sedan or a multi-purpose vehicle.


Passenger Cars and Station Wagons

For sedans in Washington, non-reflective tint is allowed only on the top 6 inches of the windshield. The rest of the windshield must remain clear to provide an unobstructed forward view.

The front side windows must allow more than 24% of visible light to pass through. The rear side windows and rear windshield must also allow more than 24% of light to enter. This setup provides sun protection while making sure the driver can still see clearly and law enforcement can see inside when needed.


Multi-Purpose Vehicles (SUVs, Vans, Trucks)

For SUVs, vans, and trucks, the windshield may also have non-reflective tint on the top 6 inches only, just like in passenger cars.

The front side windows must allow over 24% of light to pass through, but the rear side windows and rear windshield can be tinted to any darkness. These rules give more freedom for privacy and UV protection in the back, while keeping visibility in the front for safe driving.

If you’re unsure which rule applies to your vehicle, check the label inside the driver’s side door. It will tell you whether your car is classified as a passenger vehicle or a multi-purpose vehicle, which determines which tinting standards you must follow.

Window Tint Reflection in Washington

Washington has clear rules about how reflective car window tint can be. The main goal is to reduce glare that might distract the driver or blind others on the road. Too much reflection from tint is not allowed, no matter the type of vehicle.


Tint Reflection for Sedans

  • Front Side Windows: Tint must not reflect more than 35% of light. Mirror-like or shiny tint is not allowed.
  • Back Side Windows: The same 35% reflection limit applies here as well. Avoid any metallic or highly reflective films.

Tint Reflection for SUVs and Vans

  • Front Side Windows: Just like sedans, tint must not reflect more than 35%. No silver, gold, or chrome-like tints.
  • Back Side Windows: These also must stay under 35% reflective. Even with more freedom in tint darkness, reflection must remain low.

Other Washington Window Tint Rules and Regulations

Side Mirrors: If your back window is tinted, your car must have dual side mirrors that provide a full rear view.

Restricted Colors: Washington bans red, yellow, and amber tint films. These can be confused with emergency vehicle lights and are not street-legal.

Certificates: Film makers must certify that their tint meets Washington state laws. Always ask your installer if the product is state-certified.

Stickers: A sticker must be placed between the film and glass on the driver’s side window. This proves that your tint follows the law and helps you avoid fines.

Legal Window Tint Certificates in Washington

In Washington, every vehicle with window tint must have a compliance sticker placed between the tint film and the glass on the driver’s side window. This sticker shows that the tint film meets state-approved standards, making it easy for law enforcement and inspectors to confirm legality.

Before tinting your car, always check with the installer to ensure the film is certified for use in Washington. Certified dealers are required to use only approved tint products. If your windows are tinted without the correct film or sticker, you could be fined or forced to remove the tint.


Medical Exemptions for Window Tint in Washington

Washington does allow medical exemptions for darker window tint. If you have a medical condition like light sensitivity, skin disorders, or eye-related problems, you may be allowed to use a tint that is darker than what the law normally permits.

To qualify, visit a licensed doctor and explain your condition. If approved, you’ll get a statement that acts as proof of exemption. Keep this document in your vehicle at all times. This special tint can make driving more comfortable while still keeping your vehicle within legal boundaries for enforcement and inspections.


Window Tint Violation Penalties in Washington

Getting caught with illegal tint in Washington can cost you. The typical fine is around $124 for a first offense. While this may not seem like much, keep in mind that officers can issue tickets for illegal tint multiple times if the issue isn’t fixed. That adds up fast.

Law enforcement officers use tint meters to test how much light passes through your windows. If your tint is too dark, you may be cited on the spot. It’s smarter to check your tint at a certified shop before facing a fine or failing a required vehicle inspection.


Risks of Illegal Window Tint in Washington

Driving with illegal window tint may seem harmless, but it can lead to serious problems. If your tint causes you to fail a safety inspection, you could lose your inspection fee and have to retest—delaying your registration renewal.

Worse, repeated offenses can lead to higher fines or even problems with your car insurance. If you’re in an accident and the illegal tint reduces visibility, your insurer may deny the claim. It’s always safer and cheaper to stay compliant with Washington’s tint laws from the start.

Common Mistakes to Avoid – Washington Tint Law 2025

Tinting front side windows below 24% VLT
Washington requires front side windows to allow at least 24 percent of visible light to pass through. Many drivers install darker film and fail vehicle inspections or receive tickets.

Applying tint too far down on the windshield
You can only tint the top six inches of the windshield. Tinting below this line violates the law and reduces visibility.

Installing reflective or mirror-like film
Washington does not allow mirrored or metallic tints. These increase glare and can cause distractions on the road.

Not checking the total VLT with factory tint
Some vehicles already have a factory tint. Adding extra film without testing the total VLT may drop it below legal limits.

Assuming rear window rules apply the same to all vehicles
Multipurpose vehicles like SUVs may have more flexibility with rear window tint. Sedans must follow stricter limits. Misunderstanding this often leads to unintentional violations.

Forgetting to carry a medical exemption certificate
Washington offers tint exemptions for medical reasons, but drivers must carry the official exemption letter in their vehicle at all times.
