In Florida, your front side windows must let in at least 28% of light (VLT). On sedans, back side and rear windows must allow at least 15%. Qualifying multipurpose passenger vehicles must allow at least 6% VLT on the back glass. Windshields may only be tinted with a non-reflective strip above the AS-1 line.
How dark can you legally tint in Florida?
VLT means Visible Light Transmission — the percentage of light a window lets through. A higher % is lighter; a lower % is darker. Limits depend on your vehicle type.
The AS-1 line is the manufacturer's mark near the top of your windshield. Tint above it must be non-reflective. Percentages shown are the minimum light that must pass through — you cannot go darker than these.
Limits apply to the measured glass-and-film combination, not the film label alone. Visible reflectance must not exceed 25% on front sides or 35% behind the driver. Vehicle classification and applicable exemptions must be checked before installation. Sources: Florida Statute 316.2953 and 316.2954.
What does VLT % actually mean?
VLT is the share of visible light that passes through the glass and film combined. 5% is nearly black; 70% is barely tinted. When Florida says 28%, it means at least 28% of light must get through.
A professional shop measures the result with a tint meter — the same tool law enforcement uses.
Reflection limits
Tint can be reflective or mirrored, but only up to a point. Florida caps how much light your film may bounce back.
Color & other rules
- Florida does not ban specific tint colors, but red and amber are commonly avoided.
- Dual side mirrors are required if the rear window is tinted.
- Film makers must certify the tint they sell in Florida.
- A compliance sticker is not required between film and glass.
Need darker tint for a medical reason?
Florida allows a medical exemption for people with conditions that require limited sun exposure — such as lupus, melanoma or light sensitivity. You'll need a signed certificate from a licensed physician or optometrist, kept in the vehicle. The exemption lets you go darker than the standard limits.
What happens if your tint is illegal?
Illegal tint is a noncriminal traffic infraction in Florida — usually a "fix-it" ticket. You may be required to remove the film and re-tint to legal limits.
Home & business windows? No VLT limit.
These darkness rules only apply to vehicles. Residential and commercial window film in Florida has no VLT restriction — go as light or dark as you like for heat, glare, privacy and UV.
