What a medical tint exemption actually is

A medical letter sits in the glove box. Does it authorize whatever tint an installer chooses? The exemption’s state, covered person, window scope and document requirements still matter. Texas and Florida illustrate different kinds of evidence.

Texas DPS’s tint guidance says the department stopped issuing Window Tint Exemption Certificates on January 1, 2019. Its medical exception instead uses a signed statement from a licensed physician or optometrist identifying the driver or occupant and the health need for sunscreening. The guidance says to keep it in the vehicle and present it at a traffic stop.

The statement is evidence for that exception. It is not a nationwide permit or a finding that every window installation is compliant. The same page separately describes the windshield and other window rules; the scope of an exception should be read with those rules before selecting film.

The DPS tint page still contains annual-inspection language. DPS’s current inspection overview says noncommercial safety inspections ended January 1, 2025, while applicable emissions tests remain. Ending that inspection program does not itself expand the tint exception.

Florida’s 2026 statute, section 316.29545, directs the department to issue certificates for specified limited-light medical conditions. It requires vehicle make, model, year, VIN, exemption decal number and registered-owner information. The certificate is nontransferable and becomes void when the identified vehicle is sold or transferred. Carrying an old owner’s certificate is therefore a different situation from a valid exemption for the current vehicle and person.

Use the actual issued or accepted document and the issuing state’s current rules. A physician’s statement, an agency certificate and a tint-shop receipt have different roles. This comparison does not claim California’s rules, current Florida form fees or cross-state recognition; those need their own current primary guidance.
