Select your state to see the legal VLT minimums for front side windows, rear windows, and windshield — updated for 2026.

| Window position | Legal minimum |
|---|---|
| Front side windows | ≥ 32% VLT |
| Rear side windows | ≥ 32% VLT |
| Rear window | ≥ 32% VLT |
| Windshield | Top 5 in. / AS-1 line, non-reflective only |
| Reflectivity limit | ≤ 20% |
Medical exemption: Georgia allows darker tint with a physician's documentation.

How tint laws actually work
VLT is what the meter reads — not what's on the box
When an officer checks your tint, they use a tint meter pressed against your rolled-up window. The meter reads net VLT — your factory glass multiplied by the film percentage. A 35% film on 75% factory glass measures 26.25% on the meter. If your state's limit is 28%, that install is illegal even though the film says “35%” on the box.
Most cars ship with 70–80% factory VLT glass on the front sides. SUV privacy glass can be as dark as 15–25% VLT. Always calculate your net VLT before choosing a film shade.
Front side vs. rear windows — different rules
Most states apply stricter limits to front side windows (the two windows next to the driver and front passenger) because they affect driver sightlines and law enforcement visibility. Rear side windows and the rear window typically have looser limits — or no limit at all — because they don't affect the driver's primary sightlines the same way.
California, Texas, Arizona, and about a dozen other states have no rear window VLT minimum as long as the vehicle has dual outside mirrors. You can legally go 5% “limo” tint on your back windows in those states.
Reflectivity rules are often forgotten
Most states also limit how reflective window film can be — typically requiring non-metallic, non-mirrored film. A few states (Georgia, Florida, Mississippi) set a specific reflectivity ceiling (usually 20–25%). Metallic and chrome films that look highly reflective from the outside are commonly illegal even if their VLT percentage would otherwise be legal.
FAQ
What is the legal window tint limit in most states?
Most states require front side windows to allow at least 35% VLT (visible light transmission), meaning no more than 65% of light is blocked. Some states like Georgia (32%), Florida (28%), Texas (25%), and New Mexico (20%) allow darker front-side tint. States like New York, California, and Pennsylvania require 70% VLT on front sides — effectively no aftermarket tint on front windows.
Can you have any darkness on rear windows?
In most states, rear side windows and the rear window have no minimum VLT requirement, or the same limit as front side windows. States like California, Texas, Illinois, and Arizona allow any darkness on rear windows, as long as the vehicle has dual outside mirrors. Check your specific state above — limits vary widely.
What happens if your tint is too dark?
Common penalties for illegal window tint include a fix-it ticket requiring removal and re-inspection, plus a fine ranging from $50 to $300+ for a first offense. In most states, the officer uses a tint meter on the rolled-up window — the meter reads the combined VLT of your factory glass plus the film, not just the film percentage.
What is a medical exemption for window tint?
Many states allow darker tint than legal limits if the driver or frequent passenger has a documented medical condition affected by sunlight — such as lupus, photosensitivity disorder, or certain skin conditions. A licensed physician provides documentation. In Georgia, for example, a medical exemption can allow front-side tint below the standard 32% minimum.
Does the VLT percentage on the film box match what the police meter reads?
No. Factory automotive glass already blocks 20–30% of light (most cars ship at 70–80% VLT glass). A 35% film on 75% factory glass yields a net 26.25% VLT — which is what the police tint meter reads. Always calculate net VLT before installing, not just the film's labeled percentage.
