Florida tint law
Is my window tint legal in Florida?
The honest answer is that nobody can tell you over the phone, and anyone who does is guessing. Not because the law is vague, but because of what it measures.
Florida measures the window, not the film
This is the part almost every tint article gets wrong. Statute 316.2953 sets the front side limit on material tested
"when applied to and tested on the glass of such windows on the specific motor vehicle"
Your car's glass is not clear. Factory door glass is typically somewhere between 70% and 80% light transmission before anything goes on it. So the figure that matters is the film and the glass together, and the two multiply.
What that means shade by shade
Front side windows have to let through at least 28% of the light. Note at least, not more than: 28 itself is legal. Here is where the common film shades actually land once they are on real glass, across the usual 70% to 80% range.
| Film | Finished window | Against the 28% front limit |
|---|---|---|
| 80% film | 56% to 64% | Clears it comfortably |
| 70% film | 49% to 56% | Clears it comfortably |
| 50% film | 35% to 40% | Clears it comfortably |
| 35% film | 24% to 28% | On the line. Clears only on the clearest factory glass |
| 30% film | 21% to 24% | Does not clear the front limit |
| 20% film | 14% to 16% | Does not clear the front limit |
| 15% film | 10% to 12% | Does not clear the front limit |
| 5% film | 4% to 4% | Does not clear the front limit |
Front side windows only. The table scrolls sideways on a phone.
Which is why 50% is the darkest film that reliably clears the front limit, and why a 35% film is a coin toss decided by whose glass it is going on.
Factory privacy glass is the same trap, upside down
Behind the driver, Florida is far more relaxed: 15% for a passenger car, 6% for an SUV, van or truck. Easy to clear, except that many SUVs leave the factory with privacy glass already around 20%. Put a dark film over that and the finished window can land under the 6% floor on a vehicle whose owner never chose anything dark at all.
So the rear glass on an SUV deserves the same check as the front, for the opposite reason.
If you bought the car already tinted
This is the common one here, and it is worth saying plainly: inheriting tint you did not choose does not inherit a clean bill of health. The film may have been legal in the state the car came from, it may have been installed to the film's number rather than the window's, or it may simply be old. A meter settles it in under a minute, and knowing is cheaper than a stop.
Moving to Florida is the same story from a different direction. Several states set their front limit at 35% or lower, so a car that was comfortably legal where it was registered can be over the line the week it arrives.
What we actually do about it
We meter the finished window before anything is cut, on your vehicle, with your glass. That is the only reading that means anything, and it is why we will not name a shade for your car over the phone. Bring it by, we will measure what is there and tell you where it sits.
If the answer is that the shade you wanted will not clear, we will say so and show you what will. The darkest legal result on your car is a real number, and it is usually better than people expect.
