The limits at a glance
Visible light transmission (VLT) is the percentage of visible light that passes through the window. A lower number means darker glass. Florida’s film limits apply to the finished glass-and-film combination, not just the percentage printed on a film box.
| Window / vehicle | Minimum VLT | Maximum reflectivity |
|---|---|---|
| Front side windowsBoth categories | 28% | 25% |
| Rear side windows & rear glassPassenger cars | 15% | 35% |
| Rear side windows & rear glassMultipurpose passenger vehicles | 6% | 35% |
These are the general film limits in §§ 316.2953–316.2954. The rear-window 6% rule is for vehicles legally classified as multipurpose passenger vehicles; don’t assume a vehicle qualifies just because it is marketed as an SUV.
Windshield tint is different
The general rule permits a transparent sunscreening strip at the top of the windshield only, outside the driver’s direct forward viewing area defined by the federal AS/1 standard. Full-windshield tint is not authorized by this general rule—even if the film is very light. See § 316.2952.
Factory glass changes the result
Existing glass already blocks some light. Adding a film labeled “28%” does not guarantee the finished window measures 28%. Have the installed window measured with an appropriate meter and confirm the vehicle category before choosing a shade.
Common questions
Is 20% tint legal in Florida?
A finished front side window measuring 20% VLT is below the general 28% minimum. Behind the driver, a finished window measuring 20% meets the general VLT minimum for both listed vehicle categories, but reflectivity and other requirements still apply. Film labels alone are not a compliance test.
Is 5% tint legal?
5% is below all the stated VLT minimums in the table, including the 6% multipurpose rear-window minimum. The statute provides measurement tolerance, but that is not a separate recommended installation target or a guarantee that a film labeled 5% is compliant.
Does ceramic film follow different rules?
Ceramic and carbon films must meet the same applicable light-transmission and reflectivity requirements. Film technology does not make a darker shade exempt. Compare the manufacturer’s actual performance specifications rather than assuming darker always means better heat protection.
What about labels, mirrors and tolerance?
Under § 316.2955, installers must affix the required compliance label inside the left door jamb, identifying the film trade name and installer or seller. Percentage measurements have a ±3 percentage-point tolerance. Under § 316.2954, a rear window made nontransparent requires compliant side mirrors on both sides. Factory glazing has a labeling exception.
What happens if tint doesn’t comply?
Operating a vehicle with material installed in violation of the applicable provisions is a noncriminal traffic infraction, punishable as a nonmoving violation. Selling or installing noncompliant material can carry separate penalties under § 316.2956. Confirm any special exemption with Florida’s licensing authority before relying on it.
