Florida lets front side windows go down to 28% VLT and the rear side windows and back glass down to 15% on a passenger car, measured with the film on the car's own glass. SUVs, vans and trucks, which the law calls multipurpose vehicles, can go as dark as 6% behind the driver. For a shop, those numbers do more than keep customers out of a ticket. They tell you which rolls to keep on the shelf.
Look at most tint rooms and you see half-used rolls in every shade, while the installers fight over the last few feet of the one everyone actually orders. That is cash sitting in a corner. Building stock around the legal limits fixes a lot of it.
Florida legal tint limits
The rules are in Florida Statutes 316.2953 (front side windows), 316.2954 (windows behind the driver) and 316.2952 (windshield). The Florida Department of Highway Safety and Motor Vehicles (FLHSMV) handles medical exemptions.
| Window | Passenger car | SUV, van, truck (multipurpose) | Shop notes |
|---|---|---|---|
| Front side windows | At least 28% VLT; reflectance no more than 25% | Same: 28% VLT, 25% reflectance | Tested with film applied to the car's glass, so factory glass counts. |
| Rear side windows | At least 15% VLT; reflectance no more than 35% | At least 6% VLT; reflectance no more than 35% | The most popular privacy upgrade. |
| Back glass | At least 15% VLT | At least 6% VLT | A tinted back window needs outside mirrors on both sides. |
| Windshield | Transparent strip only, above the AS-1 line | No film in the driver's forward view below AS-1. | |
VLT means visible light transmission. A lower number is a darker window: 15% VLT lets 15% of visible light through. A violation is a noncriminal, nonmoving traffic infraction.
Stocking for 28% on the front windows
The front doors are where most tickets happen, and the trap is net VLT. Factory glass already blocks some light. If the glass passes about 80% and you lay a 28% film over it, the result is roughly 0.80 x 0.28 = 22%, which fails in Florida.
So most shops do not stock a 28% roll for fronts. They stock a 30% or 35% film and meter every car before it leaves. Which one works depends on the glass, so meter the bare glass first on anything unusual. A 35% ceramic gives you the most room; a 30% gets closer to the limit on clear factory glass.
Stocking for 15% on the rear windows
For sedans and coupes, 15% is the darkest legal rear shade and the one most customers ask for. It hides what is on the back seat and is easier to shrink and lay than 5% limo film. For SUVs, vans and trucks, many factory rear windows are already privacy glass, and the law allows down to 6%, so a lighter film over factory privacy glass is a common job.
That gives you a short core list: one front shade around 30% to 35%, a 15% rear shade, a darker rear shade for SUVs, and a clear high-VLT ceramic for customers who want heat rejection with no visible darkening. Everything else can be ordered when someone actually asks for it.
Florida heat and why film choice shows up in callbacks
Long summers, strong UV and humidity are hard on window film. Cheap dyed film fades, and in that heat it can turn purple and bubble within a few years. Each of those cars comes back as removal labor, baked-on adhesive on the defroster lines, and a free reinstall.
Ceramic film uses inorganic particles that do not fade like dye, and it rejects infrared heat at light shades. That matters on the front doors, where the law keeps the film fairly light. A 30% ceramic on the front can keep a cabin cooler than a much darker dyed film, because heat rejection comes from the film's makeup, not its darkness.
Buying factory-direct
A short shade list also makes buying simpler. Fewer SKUs means you can order full rolls of the shades you burn through, cut less scrap, and keep less money on the shelf.
On our list, the front-door shade that leaves room is WA38, a dyed film at a nominal 39%. On 80% factory glass that lands around 31%. Our 30% nano ceramic grades (WV30, WU30) would read about 24% on the same glass, so they are not a Florida front-door film. For sedan rears, WV20 (nominal 20%) reads about 16% on that glass. WU15, at a nominal 16%, can drop under 15% on the car. WV70 and WU70 are the clear heat-rejection films. WA is 1.5 mil with a 5-year warranty; WV is 1.88 mil and WU is 2 mil (WU70 is 1.88 mil), both with a 7-year warranty. Nominal VLT is the film on its own, so the meter on the finished window still decides. Rolls are 60 in x 98 ft (1.52 m x 30 m).
HIGHCOOL makes Window Film in our own 20,000 m² factory in Shanghai and sells it factory-direct to shops and distributors in more than 60 countries. Window Film ships from China, so plan your reorders with that in mind. Free A4 samples come from our US sample stock, and you pay only the shipping, which lets you meter our film on real Florida glass before you commit. You can find more shop guides on the HIGHCOOL blog.
If you are setting up a Florida shade list, send us the shades and monthly roll volume through the contact page, or look through our Window Film collection first.
FAQ
Can a shop legally install 15% VLT film on the front windows in Florida?
No, Florida front side windows must pass at least 28% of visible light with the film on the glass. A 15% film on the front doors fails on almost any car. Shops usually use a 30% to 35% film and meter the result.
How dark can rear windows be in Florida?
Rear side windows and the back glass can go down to 15% VLT on a passenger car. SUVs, vans and trucks can go down to 6%. If the back window is tinted, the car needs outside mirrors on both sides.
Are there medical exemptions for darker tint in Florida?
Yes, Florida allows darker tint for drivers with a qualifying medical condition, such as lupus or severe light sensitivity. The exemption is issued through the FLHSMV with documentation from a physician. The driver should keep the exemption certificate in the car.
