Florida Window Tint Laws: Legal VLT Limits for 2026

Part of our Ceramic Window Tint service.

What VLT actually means

VLT stands for Visible Light Transmission, the percentage of light that passes through the glass plus the film. A 28% film lets 28% of light through, so lower numbers are darker. Florida writes its rules in VLT, and the number that matters is the combined reading of the film and the factory glass, not the film alone. Most factory auto glass already blocks a slice of light, which is why an installer measures your glass before recommending a shade. If you want the darkest legal result, ask for a meter reading on the finished window rather than trusting the film box.

Under Florida Statutes 316.2953 and 316.2954, a sedan may have no less than 28% VLT on the front side windows, no less than 15% on the back side windows, and no less than 15% on the rear window. Multipurpose vehicles, which covers most SUVs, vans and trucks, follow the same 28% front side rule but may go to 6% VLT on the back side windows and the rear window. That difference is why a Tahoe can run limo-dark rear glass while a Camry cannot.

Windshield, reflectivity and color rules

Florida allows non-reflective tint on the windshield above the AS-1 line, the small marking etched near the top of most windshields. Below that line the windshield must stay clear, though a clear ceramic film with no visible shade is a common way to cut heat without adding darkness. Reflectivity is capped too: front side windows may not be more than 25% reflective and back side windows not more than 35%. Florida also requires dual side mirrors when the rear window is tinted.

Medical exemptions and enforcement

Florida provides a medical exemption for drivers with conditions such as lupus, photosensitivity or certain skin cancers. It requires a physician or optometrist certification submitted to the Department of Highway Safety and Motor Vehicles, and the approved certificate must stay in the vehicle. Without that paperwork, an officer measuring an illegal shade can issue a non-moving violation, and the tint typically has to be removed before the ticket clears. Sticker requirements also apply to legally tinted vehicles, so ask your installer to leave the compliance label in place.

Darkness and heat rejection are not the same thing. A modern ceramic film at a legal 30% to 35% VLT can reject far more infrared heat than a cheap dyed 5% film, because the performance comes from the nanoceramic layer rather than the pigment. For Tampa drivers who park outside all day, the practical setup is a legal shade on the front doors, a matched or darker legal shade in the rear, and a clear ceramic windshield film. Because we install mobile, we can meter your glass in your own driveway before anything gets applied.
