The quick answer: Florida's minimum visible light transmission (VLT) is 28% for front side windows, 15% behind the driver on passenger cars, and 6% behind the driver on qualifying multipurpose passenger vehicles. These limits apply to the glass and film together, not just the percentage on a film box. Windshield sunscreening is generally restricted to the upper AS-1 area; exemptions have separate requirements.
Florida Legal Tint Percentages at a Glance
The table covers ordinary aftermarket film installations without a qualifying exemption. A lower VLT number means a darker window.
| Window | Passenger cars | Qualifying multipurpose vehicles |
|---|---|---|
| Front side windows | At least 28% VLT | At least 28% VLT |
| Rear side windows | At least 15% VLT | At least 6% VLT |
| Rear window | At least 15% VLT | At least 6% VLT |
| Windshield | Transparent sunscreening strip confined to the upper AS-1 area; keep the driver's direct forward view clear. | |
Front side windows may have no more than 25% visible-light reflectance; windows behind the driver no more than 35%. When the rear window is made nontransparent, compliant outside mirrors are required on both sides. Florida's multipurpose classification depends on vehicle design, so confirm your specific SUV, truck or van rather than assuming it qualifies.
Why the Film Percentage Alone Is Not Enough
VLT measures how much visible light passes through a window. Your factory glass already reduces some light, and adding film reduces it further. For example, glass at 80% VLT with film at 35% VLT gives an approximate combined result of 28% (0.80 × 0.35). That is an illustration, not a substitute for measuring your actual windows.
Existing tint, factory privacy glass and variations between vehicles affect the result. Ask your installer to assess the glass and film combination before choosing a shade. Florida provides a ±3 percentage-point measurement tolerance; use the stated limits as your target rather than planning around that tolerance.
Want Heat Rejection Without Going Too Dark?
Darkness and heat performance are different choices. Compare the selected film's published heat-rejection specifications, appearance, visibility and warranty instead of choosing by shade alone. Ceramic film can be worth discussing when cabin comfort matters, but ceramic technology does not exempt a film from tint laws.

Windshield Tint: Do Not Assume Clear Film Is Automatically Legal
Section 316.2952 permits a transparent sunscreening strip in the upper AS-1 portion, outside the driver's direct forward viewing area. Use your windshield's AS-1 boundary rather than a universal “top six inches” rule.
The statute does not give ordinary full-windshield sunscreening film a blanket exemption just because it is marketed as clear or ceramic. Before choosing full-windshield film, confirm whether a valid statutory exemption applies to your situation.
Installer Labels and Medical Exemptions
Compliance label: Section 316.2955 requires the installer to affix a compliance label inside the left door jamb. It identifies the film trade name and installer or seller. Factory glazing that meets the specified federal standard is exempt from labeling.
Medical exemption: Section 316.29545 provides a state-issued exemption process for qualifying conditions requiring limited light exposure. An approved certificate can cover the windshield as well as side and rear windows. A doctor's note alone is not the state-issued certificate. See the official FLHSMV medical exemption application for instructions.
Already Have Tint That May Be Too Dark?
Buying a used vehicle with tint does not establish that it complies. A tint violation can result in a noncriminal, nonmoving traffic citation; amounts and procedures depend on the applicable penalty and court costs. If you received a citation, follow its instructions and deadlines.

Frequently Asked Questions
Is 20% tint legal in Florida?
If the installed glass-and-film combination measures 20% VLT, it is below the ordinary 28% front-side limit. It exceeds the rear-window VLT minimums, but reflectivity and other requirements still apply. A film labeled “20%” is not the same as a measured 20% window.
Is 5% limo tint legal on an SUV or truck?
The stated rear-window minimum for qualifying multipurpose vehicles is 6% combined VLT. Do not assume a 5% film is compliant, and the ordinary front-side minimum remains 28%.
Is ceramic tint legal in Florida?
Ceramic describes a film technology. Compliance depends on where it is installed, the measured glass-and-film result, reflectivity and any applicable exemption.
Can clear ceramic film cover the whole windshield?
Clear or ceramic branding does not create a blanket legal exception for full-windshield sunscreening. The general rule allows an upper AS-1 strip; confirm a valid exemption before going beyond it.
