Florida's window tint rules are based on how dark the tint is and which windows you tint

Florida measures window tint darkness using a number called Visible Light Transmission (VLT), which is the percentage of light that passes through the glass. The darker the tint, the lower the VLT number. Florida law sets different limits for different windows on your vehicle, and the rules are the same whether you tint them yourself or have a shop do it.

The state does not ban window tint entirely. You can legally tint your windows if you stay within the limits for each window type. If your tint is darker than the law allows, you can receive a traffic citation, and you will be ordered to remove it. The fine is typically between $100 and $150, though the exact amount varies by county.

Key Takeaways

  • Front side windows must allow at least 28 percent of light through; rear and back windows can be any darkness.
  • Your windshield can have a tint strip along the top but only if it does not extend below the manufacturer's AS-1 line (usually about six inches down).
  • Reflective or mirrored tint is not allowed on any window in Florida.
  • Medical exemptions exist for people with light-sensitive conditions, but you must carry documentation from a licensed physician and display a special permit on your vehicle.

Front side windows: the 28 percent rule

Your front side windows—the two windows next to the driver and front passenger—must allow at least 28 percent of visible light to pass through. This is the strictest limit in Florida. A tint at 28 percent VLT is noticeably dark but still allows you to see clearly from inside the vehicle and allows others to see in.

If you are shopping for tint film or visiting a tint shop, ask them to confirm the VLT percentage before installation. Many shops have sample swatches you can hold up to a window to see how dark it will look. The 28 percent rule applies whether your car is a sedan, SUV, or truck.

Rear and back windows: no limit

Your rear side windows and rear window (the back glass) can be tinted as dark as you want under Florida law. Many people choose to tint these windows completely black for privacy. There is no VLT minimum for these windows, so you have full freedom here.

This is why you often see vehicles with clear front windows and very dark rear windows—the owner is following the law while maximizing privacy in the back. If you want maximum tint darkness, focus your budget on the rear windows where there is no restriction.

Windshield tint and the AS-1 line

You can tint your windshield, but only in a narrow band along the top. The tint cannot extend below the AS-1 line, which is a line marked by the vehicle manufacturer on the windshield itself. On most vehicles, this line is about five to six inches down from the top of the windshield. If you cannot see the line, your vehicle's manual will tell you where it is, or a tint shop can identify it for you.

The purpose of this rule is to keep your view of the road clear. A tint strip across the top of the windshield reduces glare from the sun without blocking your sight lines. If your tint extends below the AS-1 line, you are in violation, even if the tint is very light.

Reflective and mirrored tint is prohibited

Florida bans any tint that is reflective or has a mirror-like finish on any window. This includes the windshield, front side windows, rear windows, and back glass. Reflective tint can create a safety hazard by blinding other drivers, and it is also used to obscure license plates, which is illegal.

If you are considering tint, make sure the film you choose is non-reflective. Most standard automotive tint films sold in Florida are non-reflective, but some specialty films are not. Ask the shop or the product label to confirm before you buy.

Medical exemptions and how to get one

If you have a medical condition that makes you sensitive to light—such as lupus, porphyria, or severe photophobia—you may be able to tint your windows darker than the law normally allows. To do this, you need a written statement from a licensed Florida physician that documents your condition and explains why you need darker tint. The statement must be on the doctor's letterhead and include their license number.

Once you have the physician's statement, you can take it to your county tax collector's office (not the DMV) and request a medical exemption permit. You will need to bring your vehicle registration and the physician's statement. The permit is usually issued the same day and costs nothing. You must display the permit on your vehicle—typically on the driver's side window—so law enforcement knows you have a valid exemption. If you are stopped, show the officer both the permit and the physician's statement.

What happens if you are cited for illegal tint

If a law enforcement officer pulls you over and determines your tint is darker than the law allows, you will receive a traffic citation. The officer may use a device called a tint meter to measure the VLT of your windows. You have the right to request that the meter be calibrated and certified, which is a defense some people use in traffic court.

The citation will order you to remove the tint within a set timeframe, usually 30 days. Once you remove it, you can return to the court or the officer's agency with proof of removal (such as a receipt from a tint shop) to have the citation dismissed. If you do not remove the tint by the important date, you may face additional fines or a failure-to-comply charge.

Frequently Asked Questions

Can I tint my windows myself, or do I have to go to a shop?

Florida law does not prohibit DIY tinting. However, if your tint is darker than the legal limit, you will be cited regardless of who installed it. Professional shops have tint meters and experience with VLT percentages, so they are less likely to install illegal tint by mistake. If you do it yourself, measure carefully and use film labeled with its VLT percentage.

Does the 28 percent rule explore to all vehicles?

Yes. The 28 percent limit for front side windows applies to cars, trucks, SUVs, vans, and motorcycles. The only exception is vehicles with a medical exemption permit. Commercial vehicles and law enforcement vehicles have different rules, but standard passenger vehicles all follow the same limits.

What if I buy a used car with illegal tint already on it?

You are responsible for the tint on your vehicle once you own it. If you are cited, you cannot use "it was already there" as a defense. If you buy a used car with tint you are unsure about, have it measured at a tint shop before you drive it, or remove it when ready to be safe.

Can I have different tint darkness on the left and right side windows?

The law does not prohibit this, but it is unusual and may draw attention from law enforcement. The safest approach is to tint both front side windows to the same darkness level at or above 28 percent VLT.

Do I need to register my tint with the state?

No, unless you have a medical exemption. Standard legal tint does not require registration or a permit. You only need to register tint if you are using a medical exemption to exceed the normal darkness limits.
