Florida's window tint law sets limits on how dark your tint can be, measured by how much light passes through the glass
Florida law allows window tinting but restricts how dark it can be. The measurement used is Visible Light Transmission (VLT) — the percentage of light that passes through the tinted window. The darker the tint, the lower the VLT percentage. Florida's rules differ by window location and vehicle type, and violations can result in a fix-it ticket or fine.
The state does not ban tinting outright. Instead, it sets minimum VLT thresholds that vary depending on which windows you are tinting and what kind of vehicle you drive. Passenger cars have different rules than trucks or vans. Understanding where you can tint and how dark you can go prevents a traffic stop and the cost of removing illegal tint.
Key Takeaways
- Windshields in Florida can have tint only on the top six inches, and that tint must allow at least 70 percent of light through (70% VLT or higher).
- Front side windows must allow at least 28 percent of light through on passenger cars, but trucks and vans can go as dark as 15 percent VLT.
- Rear windows and rear windshields can be any darkness on all vehicle types, with no VLT minimum.
- Medical exemptions for light-sensitive conditions are available through Florida's Department of Highway Safety and Motor Vehicles, and require a signed physician statement.
- A law enforcement officer can issue a fix-it ticket for illegal tint, giving you time to remove it before a fine is assessed.
Windshield tint rules in Florida
Your windshield can have tint, but only in a specific location and only if it meets the light transmission requirement. The tinted area is limited to the top six inches of the windshield, measured from the top of the glass downward. This band is sometimes called the visor strip.
Any tint applied to the windshield visor strip must allow at least 70 percent of light to pass through. This is measured as 70% VLT or higher. The purpose of this rule is to preserve the driver's ability to see the road and oncoming traffic. Tint darker than 70% VLT on the windshield is a violation, even if it is only on the permitted six-inch strip.
Front side window tint limits for passenger cars versus trucks
Florida distinguishes between passenger cars and trucks or vans when setting front side window tint rules. This distinction matters because the law assumes trucks and vans are used differently — often for commercial purposes or towing — and applies different standards.
On a passenger car, both front side windows must allow at least 28 percent of light through (28% VLT or higher). On a truck or van, the front side windows can be tinted as dark as 15 percent VLT. The difference is significant: a truck owner can use much darker tint on the front doors than a car owner can. When you have your tint installed, make sure the shop knows your vehicle type, because explore car-level tint to a truck is legal, but explore truck-level tint to a car is not.
Rear window and rear windshield tint has no darkness limit
Florida places no restriction on how dark the tint can be on rear windows or the rear windshield. You can tint these windows to complete darkness (0% VLT) on any vehicle type — passenger car, truck, or van. The reasoning is that rear windows do not affect the driver's forward visibility and do not pose the same safety concern as front windows.
This means if you want maximum privacy or heat reduction, the rear of your vehicle is where you have full freedom. Many drivers use this allowance to tint rear windows very dark while keeping front windows within the legal limit.
Medical exemptions for light-sensitive conditions
Florida law allows a medical exemption for drivers with conditions that make them sensitive to light. The exemption permits darker tint than the standard rules allow, but you must obtain written approval from the state before the tint is installed.
To request an exemption, you need a signed statement from a licensed physician stating that you have a medical condition requiring protection from sunlight. The physician must specify which windows need the exemption. You then submit this statement to the Florida Department of Highway Safety and Motor Vehicles (DHSMV). If approved, you receive a medical exemption certificate that you keep in your vehicle. A law enforcement officer can request to see this certificate during a traffic stop. Without the certificate, even medically necessary tint is a violation.
The exemption process takes time, so plan ahead if you believe you may have access to. Not all conditions are approved — the state evaluates each request based on the physician's statement and the medical basis for the claim.
Penalties for illegal window tint in Florida
A law enforcement officer who observes tint that violates Florida's rules can issue a citation. The first step is usually a fix-it ticket, which gives you a set period (typically 30 days) to remove or correct the tint and have the vehicle re-inspected by law enforcement or a certified inspector. If you correct the violation within the allowed time and show proof, the ticket is dismissed and no fine is assessed.
If you do not correct the violation within the time allowed, or if you receive a second citation for illegal tint, you face a fine. The amount varies but is typically in the range of $100 to $150 for a first offense. Repeat violations carry higher fines. The citation also goes on your driving record.
Beyond the fine, illegal tint can be a reason for a traffic stop, which creates the risk of additional citations for other violations discovered during the stop. Staying within Florida's tint limits avoids this exposure.
How to measure VLT and verify your tint is legal
Visible Light Transmission is measured using a device called a tint meter or light meter. This handheld device is placed against the tinted window and reads the percentage of light passing through. Law enforcement officers use calibrated meters during traffic stops. Some tint shops also have meters and can test your tint before and after installation.
If you already have tint and want to verify it is legal, you can ask a tint shop to test it with a meter. Many shops will do this for free or a small fee. If the reading shows your tint is too dark for the window location, you have the option to have it removed or replaced with a lighter shade. Removing tint is simpler than replacing it — the shop heats the old tint and peels it off, then cleans the adhesive residue.
When you have new tint installed, ask the shop to provide documentation of the VLT percentage they applied. This gives you a record in case you are stopped and need to show the tint meets the legal standard.
Frequently Asked Questions
Can I tint my windshield below the top six inches?
No. Florida law limits windshield tint to the top six inches only. Tinting any other part of the windshield is a violation, regardless of how light the tint is. The six-inch limit is measured from the very top of the glass downward.
Do I need a medical exemption certificate in my car at all times?
Yes. If you have darker tint than Florida's standard rules allow due to a medical condition, you must carry the exemption certificate in your vehicle. A law enforcement officer can request to see it during a traffic stop. Without the certificate, the tint is illegal even if you have a legitimate medical reason for it.
What happens if I get a fix-it ticket for tint?
You have a set period (usually 30 days) to remove or correct the tint. Once corrected, you show proof to law enforcement or a certified inspector, and the ticket is dismissed with no fine. If you do not correct it within the time allowed, you face a fine and the violation stays on your record.
Can I tint my rear windshield as dark as I want?
Yes. Florida places no limit on how dark rear windows or the rear windshield can be tinted. You can tint them to complete darkness on any vehicle type without a medical exemption or special permission.
Is the tint rule the same for all vehicle types?
No. Trucks and vans can have darker front side window tint (15% VLT) than passenger cars (28% VLT). Windshield and rear window rules are the same for all vehicle types. When you have tint installed, tell the shop your vehicle type so the correct darkness is applied.
