400+ 5 Star Reviews 
Getting pulled over for illegal window tint is frustrating, especially when it’s completely avoidable. Whether you’re shopping for a new tint job or trying to figure out if your current tint is street-legal, understanding window tint percentages by state is the first step to staying compliant and avoiding fines.
The problem is there’s no single national standard. Every state sets its own rules, and the differences can be significant. A tint that’s perfectly legal in Arizona could get you a fix-it ticket in California. This guide breaks down legal car tint percentage laws for all 50 states, explains how to read the numbers correctly, and helps you make a smart decision before your next installation.
What Do Window Tint Percentages Actually Mean?
Window tint is measured by Visible Light Transmission, or VLT. VLT is the percentage of visible light that passes through the entire window, including the factory glass and the tint film.
The lower the percentage of tint on car windows, the darker the glass appears.
Common tint levels:
- 5% VLT: Extremely dark, often called limo tint
- 20% VLT: Dark and commonly used on rear windows
- 35% VLT: Medium-dark and one of the most common legal front window options
- 50% VLT: Light tint with mild glare reduction
- 70% VLT: Very light and close to clear
Is 35% or 20% tint darker? 20% is darker. It allows less light to pass through than 35%. The lower the number, the darker the window.
States regulate legal tint levels primarily for two reasons: nighttime visibility and officer safety during traffic stops. That is why front side windows almost always have stricter limits than rear windows.
How to Read Window Tint Laws
Every state divides window tint laws into four areas:
Windshield: Usually limited to a non-reflective strip at the top above the AS1 line. Full windshield tint is illegal in nearly every state.
Front Side Windows: The windows next to the driver and front passenger. These have the strictest legal tint level requirements.
Rear Side Windows: Windows behind the B-pillar. Many states allow darker tint here.
Rear Window: The back glass. Often follows the same rules as rear side windows.
In addition to VLT, many states regulate:
- Reflectivity limits
- Prohibited colors such as red or amber
- Dual side mirror requirements if the rear window is heavily tinted
Combined VLT: What Most Drivers Overlook
Your factory glass already blocks light, typically around 70 to 80 percent VLT. When film is added, the final light transmission is lower than the film rating alone.
For example, a 35% film installed on glass that measures 80% VLT results in roughly 28% combined VLT. Law enforcement measures the final combined number, not just the film.
A professional installer should measure your factory glass before recommending a film to ensure the final result meets state law.

DC maintains some of the strictest tint rules in the country, consistent across all windows.
Darkest Legal Tint: What’s Allowed Where?
One of the most important things you must know about window tinting is that there is no single darkest legal tint that applies nationwide. Tint laws vary by state and by window position.
For front side windows, 35% VLT is the most common minimum legal tint level. Some states are stricter and require 50% to 70%, including California, New York, and Pennsylvania. A few states allow darker front tint, such as 20% in New Mexico and 25% in states like Texas and Oklahoma.
For the rear side and rear windows, the rules are often more flexible. Many states allow very dark tint, including 5% limo tint, as long as the vehicle has functioning dual side mirrors.
What States Allow 5% Tint?
Another important thing you must know is that 5% tint is generally permitted only on rear side and rear windows. It is not legal on front-side windows for standard passenger vehicles in any state.
States that allow 5% on rear windows include Florida, Arizona, Texas, Nevada, and Michigan, among others. Always verify the law based on window position, since legality depends on where the tint is installed.
| Most Permissive (Rear Windows) | Most Restrictive (All Windows) |
| Florida, Arizona, Texas, Nevada, Michigan | New York, New Hampshire, Delaware, Pennsylvania, DC |
Medical Exemptions for Window Tint
Many states allow drivers to use darker window tint than the standard legal limit if they have a qualifying medical condition. Conditions that may qualify include lupus, photosensitivity disorders, certain skin conditions, albinism, and specific eye disorders.
In most states, the process works like this:
- A licensed physician provides written documentation, you submit the required form to your state’s DMV, and you keep proof of the exemption in your vehicle at all times.
- Requirements vary. Some states issue official exemption certificates, while others require only medical documentation during a traffic stop.
Even with a medical exemption, full windshield tint is rarely permitted. If you believe you qualify, confirm the process with your DMV before installation. An experienced tint shop can help ensure the film selected meets exemption guidelines and is properly documented.
What Happens If Your Tint Is Illegal?
Penalties for illegal window tint can include fix-it tickets, fines, or both. In many states, you must remove the film and provide proof of correction. That means paying for removal and, if you still want tint, paying again for reinstallation.
Illegal tint can also cause you to fail a vehicle inspection. In some cases, if reduced visibility is determined to be a contributing factor in an accident, it may complicate insurance claims.
Choosing a compliant legal tint level from the start is far less expensive than removing and replacing film later.
How to Choose the Right Tint for Your State
Knowing your state’s minimum VLT is only the first step. The law applies to the combined VLT of the factory glass and the film together.
Factory glass typically measures between 70% and 80% VLT. When film is added, the final number decreases. For example, if your state requires 70% on front side windows and your factory glass measures 75%, even a light film can push you below the legal limit.
That is why compliant installations often use very light films on front windows in stricter states.
Beyond the percentage of tint on car windows, consider film type. Dyed, metallic, carbon, and ceramic films can all meet legal tint levels, but they differ in performance:
- Heat rejection
- UV protection
- Signal interference
- Color stability over time
Ceramic tint offers strong heat rejection without interfering with radio or phone signals and maintains its appearance longer than basic dyed film.

Frequently Asked Questions
Is 35% or 20% tint darker?
20% is darker. The percentage refers to how much visible light passes through the window. A 20% tint allows less light than 35%, so it appears darker.
What is the darkest legal tint in all states?
There is no single legal tint level nationwide. For front side windows, 35% VLT is the most common limit. Some states allow darker tints, such as 20% to 25%, while others require lighter tint between 50% and 70%. For rear windows, many states have no minimum and allow very dark tint, including 5%.
What states allow 5% tint?
5% tint is generally legal only on rear side and rear windows. It is not legal on front side windows for standard passenger vehicles. States that allow 5% on the rear include Florida, Arizona, Texas, Nevada, and Michigan. Always confirm by window position.
In what state is 20% tint legal on front windows?
New Mexico allows 20% on front side windows. Some states allow 25%, including Arkansas and Oklahoma. Laws vary, so verify current regulations before installation.
Does the tint percentage apply to the film or the whole window?
The law applies to the entire window. This means the combined VLT of the factory glass and the tint film. Installers should measure factory glass to ensure the final result meets legal requirements.
Can I tint my windshield?
Most states allow only a small non-reflective strip at the top of the windshield above the AS1 line. Full windshield tint is illegal in nearly all states for standard passenger vehicles.
Do I need special mirrors if my rear window is tinted?
Many states require functioning dual side mirrors if the rear window is tinted below a certain level. Check your state’s specific requirements before installation.
