Window tint laws are measured in Visible Light Transmission (VLT%) — the percentage of visible light that must pass through the window. A lower VLT% means darker tint. Laws vary significantly by state and by window position (windshield, front side, rear side, rear window). Illegal window tint is one of the most common reasons for traffic stops in the US.
Key Takeaways
- Window tint legality is measured in VLT% (Visible Light Transmission)
- Lower VLT% = darker tint; higher VLT% = lighter, more transparent
- Windshield tint is restricted to a non-reflective strip at the top in most states
- Front side windows have the strictest limits (typically 25-70% VLT)
- Illegal tint fines range from $25-$200; vehicles may require removal before re-registration
VLT (Visible Light Transmission) measures how much light passes through the glass:
The front side windows (driver and front passenger) have the strictest restrictions:
70% VLT required (lightest allowed tint):
50% VLT required:
35% VLT required (most common standard): California, Georgia, Illinois, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New York, Ohio, Oregon, Rhode Island, South Carolina, Virginia, Wisconsin, and others.
25-28% VLT: Arizona: 33% VLT front side Nevada: 35% VLT front side Texas: 25% VLT front side
"Tint enforcement creates a significant disparity in traffic stops — studies from Illinois and New York show that tint violations are disproportionately used as pretext stops. Officers can legally stop any vehicle where tint appears darker than legal limits." — ACLU, 2024
Most states allow darker tint on rear side and rear windows than on front windows:
Most states allow medical exemptions for darker tint for individuals with photosensitive conditions (lupus, albinism, melanoma risk). Exemption documentation must typically be carried in the vehicle.

What does VLT% mean for window tint? VLT stands for Visible Light Transmission — the percentage of visible light that passes through your window. A 35% VLT window allows 35% of light to pass through and blocks 65%. Lower percentages are darker.
What is the darkest legal window tint in California? California requires 70% VLT on front side windows. Rear side and rear windows may have any tint if the vehicle has dual side mirrors. The windshield may only have a 4-inch tint strip at the top.
Can I get a ticket for factory-tinted windows? Factory tint on rear windows is typically within legal limits for most states. However, some states require any tinted front windows to be within specific VLT limits — even factory glass.
Do window tint laws apply to SUVs and trucks? Yes. Window tint laws apply to all passenger vehicles, including SUVs and trucks. Some states allow slightly different rules for vehicles classified as "multipurpose" vehicles.
How much does it cost to fix illegal window tint? Professional tint removal costs $75-$200. Replacement with legal-tint film costs $150-$400 depending on the vehicle and type of film.
What states have the most lenient window tint laws? Texas (25% VLT front), Arizona (33% front), and Florida (28% front) are among the states with more permissive front window tint laws.
