How Dark Can You Legally Tint Your Car Windows in Florida?

Front side windows, every vehicle: Florida Statute 316.2953 requires front side windows, meaning the side wings and the windows next to the driver's seat, to allow at least 28% visible light transmittance, with a maximum of 25% solar reflectance measured on the non-film side of the glass. Rear side windows and rear windshield, sedans and passenger cars: sedan rear side windows and the rear windshield must allow at least 15% visible light transmittance. Rear side windows and rear windshield, SUVs, vans and multipurpose vehicles: Florida Statute 316.2954 covers multipurpose vehicles separately from passenger cars, and it allows back side windows and the rear window to go as dark as 6% visible light transmittance. That is the single biggest practical difference between vehicle types under Florida's tint law: an SUV or van owner can legally run a much darker rear tint than a sedan owner. Rear window solar reflectance: the rear window has a maximum solar reflectance of 35%. The windshield: Florida does not regulate the windshield by a visible light percentage the way it regulates the side and rear windows. Non-reflective tint above the windshield's AS-1 line, the manufacturer-marked line near the top of the glass, is generally allowed. Medical exemptions: the Florida Department of Highway Safety and Motor Vehicles can exempt a vehicle from the standard tint limits in Florida Statutes 316.2953, 316.2954 and 316.2956 for a documented medical condition. The exemption is requested using form HSMV 83390. Darkness is not the same question as heat: ceramic film is chosen for infrared heat rejection, not for how dark it looks. Even a clear ceramic film blocks more heat than a dark dyed "limo" film, because the two films work on different parts of the light spectrum. That matters here specifically because it means a driver does not have to choose between staying under Florida's legal limit and keeping the car cool. A fully legal 28% ceramic film on the front windows can reject more heat than an illegally dark dyed film ever will. These are the limits as of September 2026. Florida's tint law can change, and a driver planning to tint a car should confirm current limits before installing film that could fail an inspection or a traffic stop.
