Washington State Tint Laws: Your Complete Guide to Compliance and Benefits
Thinking about tinting your car windows in Washington? Here’s everything you need to know to stay legal, safe, and stylish on the road.

Following Washington State tint laws isn’t just about avoiding a ticket—it’s about ensuring safety, protecting your investment, and staying confident on the road. Illegal tint can reduce visibility for law enforcement, emergency responders, and even you as the driver, especially at night or in poor weather.
By staying compliant, you safeguard yourself from fines, failed inspections, and the hassle of having to remove or replace your tint. Plus, legal tint still gives you all the benefits — UV protection, heat reduction, and added privacy — without the stress of wondering if you’ll be pulled over. In short, following the law means driving with peace of mind, style, and safety.
What Is VLT (Visible Light Transmission)?
VLT is the percentage of visible light that passes through your vehicle’s windows. A higher VLT percentage means a lighter tint. For example tint with a 24% VLT is quite dark. It allows only 24% of light through.
Legal Tint Limits in Washington State
Washington State tint laws differentiates between sedans and multi-purpose vehicles like SUVs and vans. Below we break down how these regulations vary based on vehicle type.

Window Tint Reflection
Window tint helps cut down glare and heat by reflecting incoming light, but Washington law sets limits on how reflective your tint can be. On the front side windows and rear side windows of sedans, SUVs, and vans, the tint must not exceed 35% reflectivity.
Other Must-Know Regulations
Mirror Requirement
If you tint the rear window, your vehicle must have dual side mirrors (both left and right) to ensure adequate rear visibility.
Prohibited Tint Colors
Colors like red, gold, yellow, or mirror-finish films are outright banned.
Certification
In order for the tint to be legal in Washington, it must be manufactured by a certified manufacturer. If you work with a reputable Seattle tint installer, they will be able to provide accurate information about the film being used.
Medical Exemptions
If a licensed physician provides written verification, darker tints beyond standard legal limits are allowed — including full tinting below the AS‑1 line or top 6" of the windshield. A reputable installer will require proof of such verification.
