Florida Window Tint Statute: VLT Limits, Exemptions, and Fines

Florida window tint laws set a minimum of 28 percent visible light transmission (VLT) on front side windows for every vehicle. Behind the driver, sedans must keep at least 15 percent VLT, while SUVs, vans, and trucks can go as dark as 6 percent. Reflectivity is capped at 25 percent on the front sides and 35 percent on rear glass, and the windshield can only carry a transparent tint strip above the manufacturer’s AS-1 line. Driving with illegal tint is a nonmoving traffic infraction; installing or selling illegal tint is a second-degree misdemeanor.

Front Side Windows

Florida Statute 316.2953 covers the windows at or forward of the driver’s seat, including the small wing windows. Tint must let through at least 28 percent of visible light, and reflectivity from the outside cannot exceed 25 percent. The rule is the same for every vehicle type.¹

That 28 percent is the combined reading of the film plus the factory glass, not the film alone. A roll advertised at 30 percent VLT can measure below 28 percent once it sits on glass that already blocks some light. This is the most common way drivers end up illegal without knowing it, so what matters is the meter reading on your window, not the number printed on the box.

Rear Windows: Sedans vs. SUVs and Trucks

Florida Statute 316.2954 splits the rules for everything behind the driver by vehicle class. Passenger cars (sedans) must maintain at least 15 percent VLT on the rear side windows and the back window. Multipurpose passenger vehicles, meaning SUVs, vans, and pickups, can go down to 6 percent VLT on those same windows. Reflectivity for rear glass is capped at 35 percent for both classes.²

If the rear window is made nontransparent by tint or any other covering, the vehicle must have compliant side mirrors on both sides under Section 316.294.²

Windshield Rules

The windshield itself is nearly off-limits. Sunscreening material is only allowed as a transparent strip along the very top, and that strip cannot extend below the AS-1 line, a marking etched or printed into the glass by the manufacturer that shows where the driver’s direct forward viewing area begins under Federal Motor Vehicle Safety Standard No. 205.³

Not every windshield has a visible AS-1 line. Where none is marked, the entire windshield must meet the federal minimum of 70 percent light transmittance, so any strip at the top must still let through at least 70 percent.⁴

Beyond that strip, the windshield may display items required by law such as registration stickers, electronic toll transponders issued by a governmental entity, and GPS or navigation devices.

Reflectivity and Color

Reflective and mirrored tint is regulated on its own. Front side windows are limited to 25 percent total solar reflectance of visible light.¹ Windows behind the driver are capped at 35 percent.²

Both statutes also prohibit sunscreening material that alters the color of the window. Film that gives the glass a distinct hue beyond simple darkening falls outside what the law authorizes. Neutral shades (charcoal, gray, or black) are the safe choice, and it is worth confirming with the installer that the product does not read as colored from outside the car.

The 3 Percent Tolerance and the Compliance Label

Every VLT and reflectance figure in Sections 316.2951 through 316.2954 carries a tolerance of plus or minus 3 percent. A front side window measuring 26 percent VLT is still inside the legal window around the 28 percent minimum. The tolerance covers small variations in testing equipment and film aging over time.⁵

Installers and sellers must also provide a compliance label with every sunscreening product. It is a pressure-sensitive, self-destructive vinyl label placed on the window so officers can see at a glance that the film was sold as meeting Florida standards. If a shop doesn’t provide one, treat that as a warning sign about the product.

Medical Exemption for Darker Tint

Florida issues medical exemption certificates to drivers with conditions such as lupus, other autoimmune diseases, or any condition that requires limited exposure to light. The exemption allows tint darker than the standard VLT limits on the windshield, side windows, and rear windows.⁶

To apply, submit Form HSMV 83390 to the Florida Department of Highway Safety and Motor Vehicles. The physician certification section must be signed by a licensed physician, dermatologist, physician assistant, advanced practice registered nurse under physician protocol, or a physician at a military medical facility, state hospital, or federal prison.⁷ The U.S. Department of Veterans Affairs adjudication office can also certify the need.⁸

The certificate lists the vehicle’s make, model, year, VIN, a medical exemption decal number, and the registered owner’s name. It is nontransferable and voids when you sell or transfer the vehicle, so a replacement car needs a new certificate. The department may charge a fee to cover issuing costs.⁶ FLHSMV procedure requires you to keep the certificate in the glove compartment at all times for verification during a stop.⁸

What a Ticket Costs

Driving with illegal tint is a noncriminal traffic infraction classified as a nonmoving violation under Chapter 318.¹ The base fine under Section 318.18 is $30. On top of that, the statute adds $18 in court costs, a $12.50 administrative fee, and a $10 Article V assessment, bringing the statewide minimum to $70.50. Many counties add local surcharges, so the final amount you pay depends on which county court handles the citation.⁹

Officers check tint on the spot with handheld light transmission meters. The device sits against the glass and returns a reading in seconds, so there is no arguing a number that comes back below the threshold.

Penalties for Installers and Sellers

Florida treats the people who install or sell non-compliant tint more seriously than the drivers. Selling or installing sunscreening material that violates Sections 316.2951 through 316.2955 is a second-degree misdemeanor, which carries up to 60 days in jail and a fine of up to $500.¹⁰

This matters to you as a customer. If a shop installs film that fails a meter test, the shop broke the law too. Reputable installers keep a tint meter on the counter and will test the finished job on your glass before you drive off. An installer who won’t test or won’t stand behind compliance is the wrong shop.

Driving Out of State

Florida’s tint limits do not travel with the car. There is no universal reciprocity between states, so once you cross a state line you are subject to that state’s tint laws even though your vehicle is registered in Florida. Some states extend visitor exemptions to out-of-state drivers; others issue citations or repair orders regardless. Florida’s 28 percent front-window limit is more permissive than many states, and its 6 percent floor for MPV rear windows is on the darker end nationally, so long trips are where conflicts are most likely.
