Florida window tint law, in plain numbers.

How VLT is measured

Visible light transmission is the share of visible light that makes it through the window. A 35% film means 35% of the light gets through and 65% does not. Lower number, darker glass.

The critical detail: the reading is taken through film plus glass together, not the film alone. Factory glass already absorbs some light — often 70 to 80% transmission on clear glass, and closer to 20% on the privacy glass in the back of an SUV. That is why the same roll of film produces two very different results on two different vehicles, and why a shop should measure your glass instead of quoting from a chart.

The windshield and the AS-1 line

Look at the top edge of your windshield near the corner and you will find a small marking that reads AS-1. Florida allows non-reflective tint above that line. Below it, film must not take the windshield under the legal transmission threshold — which in practice means clear film only.

A full clear ceramic windshield film is legal because it does not meaningfully reduce visible light. It is one of the most effective single upgrades in this climate: the windshield is the largest piece of glass on the car and the one pointed at the sun most of the day.

Reflectivity

Separate from darkness, Florida caps how mirrored the glass may look. Front side windows may not be more than 25% reflective, and back side windows not more than 35%. This is what rules out the heavily mirrored films you sometimes see. Ceramic film is non-reflective, so it is not a concern with what we install.

The sticker

Florida requires a label identifying compliant film, placed between the film and the glass on the driver's side. We apply it as part of every installation. It is small, it is easy to miss, and it is the first thing an officer looks for.

Medical exemptions

Florida Statute 316.2954 provides for a medical exemption where a physician or optometrist certifies a condition requiring limited exposure to sunlight — lupus, certain photosensitivity disorders and some post-surgical conditions among them. The exemption is applied for through the Florida Department of Highway Safety and Motor Vehicles, and the certificate must be carried in the vehicle.

If you hold one, bring it to your appointment and we will install to what your exemption allows.

What a violation actually costs

Under Florida Statute 316.2957, a tint violation is a noncriminal traffic infraction handled as a nonmoving violation. In practice that means a citation, and frequently an instruction to remove the film and show proof of compliance. The film comes off, you pay for it twice, and you still do not have tint.

Four mistakes we see constantly

• Assuming factory privacy glass is the film. It is glass, and it counts toward your total. Film on top of it stacks.
• Buying 20% for the front doors. It is under the 28% limit on every vehicle in Florida, no exceptions.
• Thinking 5% is legal on the back of an SUV. The limit there is more than 6%. Five percent misses it.
• Confusing dark with cool. Darkness is a legal question. Heat rejection is a film-quality question. A legal ceramic 35 will outperform an illegal dyed 5 on the thing you actually care about.
