Does Florida have a medical window tint exemption?
Yes. Florida is one of the many states that allow drivers with a documented medical need to use darker window tint than the standard limits. The state's process is built around a specific form: HSMV 83390, issued by the Florida Department of Highway Safety and Motor Vehicles. That form has to be signed by a physician or optometrist who confirms the medical need.
The exemption exists for people whose condition is made worse by sunlight or bright light through car glass. Common examples include lupus, porphyria, a history of skin cancer, albinism, and severe photophobia from eye or neurological conditions. See our overview of conditions that may qualify for more.

How to get a Florida medical tint exemption, step by step
- 1Get a physician's evaluation. A licensed physician reviews your medical history and confirms you have a condition that makes sun exposure harmful or painful.
- 2Get the signed documentation. The physician signs a certificate describing your medical need. With ShadedMD, this is emailed to you as a PDF.
- 3Complete form HSMV 83390. Florida's form requires the signature of a physician or optometrist. Your ShadedMD certificate comes with guidance on how the form works.
- 4Install tint within the exempt limits. Take your paperwork to a reputable tint shop and ask for film within whatever Florida allows for exempt vehicles.
- 5Keep your documents in the vehicle. If you are stopped, show your exemption paperwork along with your license and registration.
The slow part of this process has always been step one. Finding a doctor who understands tint exemptions, booking an appointment, and paying for an office visit can take weeks. ShadedMD removes that friction entirely.

What the Florida exemption does and does not cover
An exemption is not a blank check for any tint you want. It allows darker tint than the standard limit, within whatever range Florida sets for exempt vehicles. It generally does not change the rules on reflective or mirror-like film, and windshield rules remain the most restrictive of all. Our guide to windshield tint rules and the AS-1 line explains why.
Florida's exemption is also tied to a process. The physician's signature is only useful if you follow through with the state's form and keep your documents where an officer can see them. Read what to keep in your car so you are prepared.
Traffic stops in Florida with an exemption
If you are pulled over for dark tint, stay calm, tell the officer you have a medical exemption, and hand over your documents. Officers can measure tint with a meter, and your paperwork explains why your windows read darker than the standard limit. Keep the originals or clean printed copies in the glove box, not just on your phone. Our article on traffic stops and travel covers what to expect.
