If you’re considering window tint for your vehicle in Washington, understanding the law is essential before booking your installation. While tinted windows offer privacy, UV protection, and a sleek appearance, they must comply with Washington State window tint laws to avoid fines or costly removal.
In this comprehensive guide, we’ll explain everything drivers need to know about legal tint percentages, reflectivity limits, medical exemptions, penalties, and compliance tips — so you can upgrade your vehicle confidently and legally.
Are Window Tints Legal in Washington State?
Yes — aftermarket window tint is legal in Washington State, but it must meet specific standards set by state law. These regulations are enforced across cities including Auburn, Seattle, Tacoma, and throughout the state.
Washington law regulates:
- Visible Light Transmission (VLT) – how much light passes through the window
- Reflectivity – how much light is reflected outward
- Windshield coverage limits
- Vehicle classification differences
Let’s break it down clearly.
What Is VLT (Visible Light Transmission)?
Visible Light Transmission (VLT) refers to the percentage of visible light that can pass through both the glass and the tint film combined.
For example:
- 50% VLT = allows 50% of light through (lighter tint)
- 24% VLT = allows 24% of light through (darker tint)
- 5% VLT = very dark “limo tint” (not legal for most front windows in Washington)
Lower percentages mean darker tint.
Legal Tint Limits in Washington State
1. Windshield Tint Laws
- Tint is allowed only on the top 6 inches of the windshield
- The tint must be non-reflective
- Full windshield tint is not permitted
This top strip (sometimes called an AS-1 line tint) helps reduce glare without obstructing driver visibility.
2. Front Side Windows (Driver & Passenger)
4
- Must allow at least 24% VLT
- Applies to most passenger vehicles
This means the tint cannot be darker than 24%. Anything darker (like 20% or 15%) would be considered illegal on the front side windows unless you qualify for a medical exemption.
3. Rear Side Windows & Rear Window

Washington law treats vehicles differently depending on classification:
For Sedans (Passenger Cars):
- Rear side windows must also allow at least 24% VLT
- Rear window must meet the same requirement
For SUVs, Vans, and Trucks (Multi-Purpose Vehicles):
- No minimum VLT requirement for rear side windows or rear window
- These windows may be darker than 24%
However, reflectivity rules still apply (see below).
Reflectivity Rules in Washington
Window tint film cannot be overly reflective.
- Tint must not exceed 35% reflectivity
- Mirror-like or metallic reflective finishes are prohibited
Highly reflective tint can impair visibility for other drivers and law enforcement, which is why Washington restricts it statewide.
Are Certain Tint Colors Illegal?
Washington State restricts certain tint colors that can obstruct visibility or appear distracting. While neutral shades (black, charcoal, gray) are generally acceptable, overly flashy or mirrored finishes are not permitted.
Always confirm with your installer that the film meets Washington standards.
Medical Exemptions for Darker Tint
Washington allows medical exemptions for drivers with qualifying health conditions such as:
- Lupus
- Severe photosensitivity
- Certain skin disorders
- Other physician-documented light sensitivity conditions
To qualify:
- You must obtain a written statement from a licensed physician
- Documentation must be kept in the vehicle
- The exemption applies only to the individual named in the documentation
Without proper paperwork, darker tint is still subject to citation.
Penalties for Illegal Window Tint in Washington
Failing to comply with tint laws can result in:
- Traffic citations
- Fines (often $100–$150 or more)
- “Fix-it” tickets requiring tint removal
- Possible re-inspection
Law enforcement officers may measure tint using a VLT meter during a traffic stop if they suspect it is too dark.
Repeat violations can increase penalties.
Why Washington Has Tint Regulations
Washington’s window tint laws are designed to balance:
- Driver safety – Ensuring adequate night visibility
- Law enforcement visibility – Officers must see inside vehicles during stops
- Public safety – Preventing dangerous glare from reflective films
While tint improves comfort and UV protection, excessive darkness can reduce visibility in rainy, foggy, or nighttime conditions — which are common in Washington.
Benefits of Legal Window Tint
When installed correctly and within legal limits, window tint provides:
✔ UV protection (blocks up to 99% of harmful UV rays)
✔ Reduced interior heat
✔ Glare reduction
✔ Increased privacy
✔ Interior preservation (prevents fading)
✔ Enhanced vehicle aesthetics
The key is choosing the correct VLT percentage for compliance.
How to Ensure Your Tint Is Legal
Before installing window tint, follow these steps:
1. Choose a Professional Installer
Work with experienced professionals familiar with Washington regulations.
2. Ask for Film Specifications
Reputable shops provide documentation showing:
- VLT percentage
- Reflectivity rating
- Manufacturer compliance standards
3. Understand Your Vehicle Type
Sedans have stricter rear-window limits than SUVs or trucks.
4. Avoid DIY Tint Kits
Improper installation can lead to bubbling, peeling, and incorrect VLT percentages — increasing your risk of citation.
