Washington Window Tint Laws Explained: What’s Legal in Vancouver, WA

October 1, 2026

If you drive in Vancouver, Washington, and you’re thinking about tinting your windows, you need to know the rules before you book an appointment. Washington State has specific laws about how dark your tint can be, and they enforce them. Get it wrong, and you could end up paying fines or having to remove film you just paid to install.

Here’s the good news: the rules aren’t complicated once you understand the basics. This guide breaks down exactly what’s legal in Vancouver, WA, what’s not, and how to stay compliant while still getting the heat rejection and privacy you want.

What Does VLT Mean and Why Does It Matter?

Visible Light Transmission, or VLT, is the percentage of light that passes through your window and tint combined. Lower numbers mean darker tint. A 5% VLT is limo dark. A 70% VLT is barely noticeable.

Washington uses VLT as the primary measurement for legal tint. When a state trooper checks your windows, they’re looking at how much light gets through, not just how dark it looks to the naked eye.

Here’s the thing: Factory tint counts too. If your vehicle came with tinted glass from the manufacturer, that tint counts toward the VLT calculation. Aftermarket film adds to it.

Washington Window Tint Laws: The Legal Limits

Washington’s tint law is in RCW 46.37.430, and it sets different rules depending on your vehicle type.

For Sedans and Passenger Cars

If you drive a standard passenger car, the rules are straightforward and strict:

What this means: You cannot go darker than 24% on any side or rear window in a sedan. No exceptions for the back seat.

For SUVs, Trucks, and Vans

Larger vehicles get more flexibility in Washington:

What this means: If you drive an SUV or truck, you can tint the back windows as dark as you want. The front side windows still need to meet that 24% threshold.

Reflectivity Rules You Shouldn't Ignore

Washington regulates more than darkness. Your tint also has to pass a reflectivity test.

Window film cannot exceed 35% reflectivity on any window. This rule applies regardless of your vehicle type.

Why it matters: Mirrored or metallic tints that bounce light back at other drivers create glare and safety hazards. Even if your tint meets the VLT requirement, a highly reflective film can still be illegal.

Tint Colors That Are Banned in Washington

Washington law outright prohibits certain tint colors, regardless of VLT. These include:

If you’re considering a colored tint for style, stick with neutral shades like gray, charcoal, or bronze. They’re more likely to comply with state standards.

What Happens If Your Tint Is Illegal?

Driving with non-compliant tint in Washington can lead to real consequences:

Traffic infraction: You can be pulled over specifically for illegal tint
Fines: Up to $136 for a violation
Mandatory removal: You may be required to remove the illegal film and pass a re-inspection
Insurance complications: If you're in an accident, illegal tint could become a factor in determining fault or liability

Here’s the thing: Washington State Patrol uses special meters to check VLT during traffic stops. You can’t talk your way out of a failed reading.

Medical Exemptions: When Darker Tint Is Allowed

Washington does allow medical exemptions for darker tint if you have a qualifying condition. Conditions like lupus, skin cancer, or severe sun sensitivity may qualify.

How to get one:

Get a written recommendation from your physician
Submit a request to the Washington State Patrol
Once approved, keep documentation in your vehicle

Without proper paperwork, a medical exemption won’t help you during a traffic stop.

How to Stay Compliant When You Get Tinted in Vancouver, WA

If you’re booking tint in Vancouver, here’s how to make sure you stay legal:

Know your vehicle type. Sedans and SUVs follow different rules. Confirm which category your vehicle falls into before choosing a tint percentage.

Ask about VLT before installation. A reputable shop will explain exactly what film they’re using and what VLT it delivers. Don’t guess.

Request documentation. Washington requires tint installers to place a compliance sticker on the driver’s side window. This sticker proves the work was done legally and identifies the installer.

Avoid bargain tint jobs. Cheap film often fades, bubbles, or fails to meet reflectivity standards. A professional installation from a certified shop protects your investment and keeps you compliant.

Consider ceramic tint. Ceramic films offer excellent heat rejection without the reflectivity problems of metallic tints. They’re a popular choice for drivers who want performance without legal issues.
