How Dark Can You Tint With a Medical Exemption? Limits by State

Does a medical exemption let you tint as dark as you want?

Usually not. A medical exemption is an exception written into your state's tint law, and the same law decides how far the exception goes. Among the states we have checked against official sources, the rules fall into three patterns:

• A fixed floor. The law or agency rule names the darkest tint an exempt vehicle may have. Georgia and Virginia work this way, and New Jersey limits exempt front side windows to light film.
• A number set by your clinician. The prescription or statement must state the percentage you need. Minnesota and Missouri work this way.
• No number at all. Texas DPS allows darker front side windows for a vehicle owner with a physician's documentation and names no minimum percentage.

A fourth group of states has no medical exemption for darker tint, or allows only clear film or removable screens. See the states with no medical tint exemption.

What are the exempt tint limits in states we have verified?

These limits come from each state's statute, rule or official agency guidance, and they apply only to vehicles with a valid exemption. For the standard limits in every state, see window tint laws by state.

Texas makes medical need a defense to prosecution, not a bar to a ticket, and its 2019 DPS notice says whether a vehicle violates the tint law is up to law enforcement and the courts. Keep your documents in the car either way.

Why does the windshield stay restricted?

The windshield is the glass you look through to drive, so states protect it more than any other window. Many limit tint to a strip along the top, often down to the AS-1 line, a mark the manufacturer puts near the top of the glass. Our guide to windshield tint rules and the AS-1 line explains how that line works.

Medical exemptions usually follow the same logic. In Georgia, Missouri, New Jersey, Texas and Virginia, an exemption allows at most a top strip or a light film on the windshield, and Georgia allows none. If glare through the windshield is your main problem, ask your clinician what else may help, and read about the best tint percentage for light sensitivity.

What else affects how dark your windows can be?

• Factory glass. Limits are measured through the glass and film together. New Jersey's rules, for example, measure light transmittance in conjunction with the factory-installed glass, so a 35% film on glass that is already slightly tinted reads darker than 35%. See window tint percentages explained.
• Measurement margin. Some states allow a small tolerance. Georgia's exempt floor is 23%, plus or minus 3%, and Missouri's standard front side limit is 35%, plus or minus 3%.
• Reflectivity. Darkness is not the only rule. New Jersey caps the reflectance of film on exempt windshields and front side windows at 8%.
• Which windows and vehicles. Exemptions often name specific windows or vehicles. Missouri's permit, for example, covers the front side windows of the vehicle you bring to the Highway Patrol.

How dark should you actually go?

The legal floor is a limit, not a target. Very dark front side windows make it harder to see at night, in rain and when backing up. Many light-sensitive drivers do well with a moderate film that also blocks UV. Our guide to the best tint percentage for light sensitivity walks through the tradeoffs, and a tint shop can show you film samples before you commit.

Ask your installer for a receipt that lists the film and the measured VLT for each window. If you are stopped, it helps show that you stayed within your exemption. Read how police measure window tint to see how officers check.

How do you get a medical tint exemption?

Every route starts with a clinician's evaluation. ShadedMD handles that step online: a physician licensed in your state reviews a 5-minute questionnaire, physicians aim to finish within 24 to 48 hours, and approved patients receive a signed certificate by email, with guidance for any state form. Some states ask for more than a signed certificate: Minnesota and Missouri expect the note to state a tint percentage, and Georgia's form has the signer attest to a personal examination.
