Window Tint Medical Exemption By State

Pick your state for an in-depth guide: the governing statute, the exemption form, the agency that processes it, and the VLT rules your exemption is measured against.

Why your state's rules matter

Every U.S. state regulates automotive window tint through a visible-light-transmission (VLT) statute, and every state carves out a medical exemption for drivers whose health condition makes tint a medical necessity. The problem: the how is different everywhere. Some states — including California and Texas — expect a signed physician letter on letterhead that you keep in the glove box. Others, like Florida and Connecticut, issue a state-specific exemption certificate that attaches to your vehicle record.

The result is that a prescription written to Alabama's ALEA standards will not satisfy a New York inspection station, and the VLT numbers your installer is aiming at — the legal tint your exemption "unlocks" — are only useful if they match the statute of the state where your vehicle is registered.

Our 2026 state guides are written against the current statute text, cite the governing code section, link to the processing agency, and identify the exemption form by name. They are not legal advice; they are a plain-English map of the process with links to the authoritative source material you can hand to law enforcement or your DMV.

Common Questions

Window Tint Medical Exemption FAQs

Which states allow a window tint medical exemption?
Every U.S. state provides some process for a medical exemption to window-tint visible-light-transmission (VLT) limits, although the documentation, form name, and processing agency differ state-by-state. The only exceptions are a handful of states where the exemption is routed through the state police rather than the DMV. Our 2026 state-by-state index links to the governing statute and the correct form for all 50 states.
Do I need a separate prescription for each state?
Yes. A window-tint medical exemption prescription or physician letter is written to comply with the specific statute of the state where your vehicle is registered. A California exemption will not be honored by a Florida trooper, and vice-versa. If you move or register the vehicle in a new state, you need a new exemption under that state's rules.
Do I need to carry the prescription in the car?
In most states, yes — the exemption is only valid when the signed physician letter, prescription, or state-issued certificate is physically present in the vehicle and can be produced on request during a traffic stop. A minority of states (e.g., Connecticut and Florida) attach the exemption directly to the vehicle registration or driver record, but even there it is strongly recommended to keep a copy in the glove box.
How dark can I tint with a medical exemption?
The legal tint darkness under a medical exemption is set by each state's statute and ranges from as light as 70% VLT (Alaska, Delaware) to as dark as roughly 20% VLT for the front sides (Illinois, New Mexico). Our state guides list the exact front, rear, and windshield rules for each jurisdiction, plus the exemption's effect on those limits.
What medical conditions qualify for a tint exemption?
Commonly accepted conditions include photophobia, lupus, systemic lupus erythematosus (SLE), xeroderma pigmentosum, retinitis pigmentosa, solar urticaria, melanoma, post-cataract surgery sensitivity, bullous pemphigoid, polymorphous light eruption, and severe migraines triggered by sunlight. State statutes typically require a licensed physician, optometrist, or ophthalmologist to certify the condition.
Is an online doctor's visit valid for the exemption?
Telehealth consultations with a U.S.-licensed physician or optometrist are accepted in every state that permits telemedicine prescribing, which is effectively all 50 states as of 2026. MyEyeRx uses licensed Optometrists and Ophthalmologists who can issue a state-compliant letter or prescription after a virtual visit — when the patient's condition medically warrants an exemption.
