What the DMV cares about with window tint
The DMV does not issue permits for window tinting, and your state does not require you to register tint with them. What matters is that your tint meets your state's legal limits — if it does not, you can be stopped by police, and the violation stays on your driving record. The DMV's role is only to know about it if you get a ticket, because some states require you to remove illegal tint before your vehicle passes inspection or before your registration renews.
Window tint laws are set by each state and sometimes by individual cities. They specify how dark the tint can be on different windows — usually measured as a percentage of light that passes through, called Visible Light Transmission or VLT. Your front windshield almost always has the strictest rules. Side windows and rear windows usually allow darker tint. Some states exempt medical tint for people with light sensitivity or skin conditions, but you typically need a doctor's letter and a special medical exemption sticker.
If you tint your windows illegally and get pulled over, the officer can issue a citation. In most states, you then have a set time to remove the tint and show proof to the court or police department — usually 10 to 30 days. If you do not comply, the violation can result in a fine, points on your license, or both.
Key Takeaways
- Each state sets its own window tint darkness limits, measured in Visible Light Transmission percentage, and the DMV enforces those limits through traffic stops, not through registration.
- Your front windshield almost always has the strictest tint rules, while rear windows usually allow much darker tint.
- If you receive a ticket for illegal tint, you typically have 10 to 30 days to remove it and provide proof to avoid a fine or points on your license.
- Medical tint exemptions exist in most states for people with documented light sensitivity or skin conditions, but require a doctor's letter and a special sticker on your vehicle.
- Tint darkness is measured by a professional tint shop or law enforcement using a light meter, not by eye.
How to find your state's tint limits
Your state's DMV website lists the legal tint percentage for each window position. Search "[your state] DMV window tint laws" or "[your state] window tint legal limits." The information is usually in a section about vehicle equipment or safety standards, not under registration or licensing.
The limits typically look like this: front windshield (often no tint or only a small strip at the top), front side windows (usually 50 to 70 percent light transmission), rear side windows (usually 35 to 50 percent), and rear window (usually 35 to 50 percent). Some states allow darker tint on rear windows than front windows. A few states have no tint restrictions at all, but most do.
If you cannot find the information on your state's DMV site, call your state's DMV customer service line or visit a local DMV office. You can also ask a professional tint shop — they work with these limits every day and can tell you what is legal in your area. Many shops will not install tint that violates state law, because they can face fines or lose their business license.
What happens if you get a ticket for illegal tint
A police officer can measure your tint with a handheld light meter during a traffic stop. If the reading shows your tint is darker than the legal limit, the officer writes a citation. The ticket usually lists the specific window that violated the law and the measured VLT percentage.
You then have a window of time — typically 10 to 30 days, depending on your state — to remove the tint. Some states allow you to remove it yourself; others require a certified tint shop to remove it and provide a receipt. You then show proof of removal to the police department, the court, or both, depending on where you received the ticket. If you do this within the important date, the ticket is often dismissed or reduced to a warning.
If you do not remove the tint in time, the violation becomes a fineable offense. Points may be added to your driving record. In some states, you cannot renew your vehicle registration until the violation is resolved. If you received the ticket in a state where inspection is required, your vehicle will fail inspection until the tint is removed.
Medical tint exemptions and how to get one
Most states allow darker tint than normal if you have a medical condition that makes you sensitive to sunlight. Conditions that typically may have access to include lupus, porphyria, xeroderma pigmentosum, and severe photosensitivity dermatitis. Some states also accept prescriptions for tint related to migraines or eye conditions.
To get a medical exemption, you need a letter from a licensed doctor stating that you have a condition requiring tinted windows and recommending a specific VLT percentage. You then take this letter to your state's DMV or your county's vehicle registration office. They issue a medical exemption sticker that you place on your vehicle, usually on the driver's side window or dashboard. This sticker tells law enforcement that your tint is legal under medical exemption.
The sticker is not permanent — it typically expires after one to three years, depending on your state. You will need to renew it by submitting a new doctor's letter. If you move to a different state, that state's exemption sticker is not valid; you must get a new one from your new state's DMV.
Scams and safety issues with tint shops
Scam alert: Some tint shops will install tint darker than your state's legal limit and claim it is legal, or they will tell you that the DMV "does not enforce" tint laws in your area. This is false. Law enforcement enforces tint laws, and you will be responsible for the ticket and removal costs. Always ask the shop to show you your state's legal limits in writing before they tint your windows.
Another common problem is poor installation. Cheap tint can bubble, peel, or turn purple within months. If you are paying for tint, use a shop with reviews and ask about their warranty. A reputable shop will may provide their work for at least one year.
Do not buy pre-tinted window film online and install it yourself unless you are experienced. Improper installation can create air bubbles that distort your view, and if the tint is too dark, you will still get a ticket. The cost of removal and a citation usually exceeds the cost of professional installation.
Tint and vehicle inspection
In states that require annual or biennial vehicle inspections, window tint is part of the inspection. If your tint is darker than the legal limit, your vehicle will fail inspection. You cannot register or renew your registration until you remove the tint and pass inspection.
Some inspection stations have a light meter on-site and will measure your tint as part of the inspection. Others do a visual check. Either way, if the inspector believes your tint is illegal, they will note it on your inspection report, and you will need to remove it before you can pass.
If you live in a state without inspections, tint violations are still enforceable through traffic stops. You can still receive a ticket and be required to remove the tint.
Tint and your insurance or registration renewal
Illegal window tint does not automatically affect your insurance rates or your ability to renew your registration — unless you have an unresolved ticket. If you received a citation for tint and did not remove it within the important date, your registration renewal may be blocked until the violation is resolved.
Some states use an automated system that flags your vehicle in the registration database if you have an outstanding tint violation. When you try to renew online or by mail, the system will reject your renewal and direct you to resolve the violation first. You may need to show proof of removal to the court or DMV before you can proceed.
If you have a tint ticket and are unsure whether it has been resolved, contact the court or police department that issued the ticket. They can tell you the status and what you need to do next.
Frequently Asked Questions
Can I tint my windshield at all?
Most states allow a small strip of tint across the top of your windshield, usually no more than 4 to 6 inches. Some states allow no windshield tint at all. Check your state's DMV website for the exact rule. The rest of your windshield must remain clear so you can see the road.
What if I moved to a new state with different tint laws?
You must comply with your new state's tint laws. If your tint was legal in your old state but is too dark for your new state, you will need to remove it or have it lightened. You can be ticketed for illegal tint as soon as you register your vehicle in the new state.
Do I need to tell the DMV I have tint on my windows?
No. The DMV does not track or register window tint. Your registration does not mention it. However, if you have a medical exemption, you will receive a sticker from your state's DMV or county registration office, and you must display it on your vehicle.
How much does it cost to remove illegal tint?
Professional removal typically costs $100 to $300 depending on how many windows need to be done and how long the tint has been on. Some tint shops offer removal as part of a package if you are having new tint installed. If you received a ticket, you may be able to remove it yourself with a heat gun and scraper, but professional removal is faster and cleaner.
Can I fight a tint ticket in court?
You can, but it is difficult to win if the officer measured your tint with a light meter and it was over the legal limit. Your best option is usually to remove the tint within the important date and ask the court to dismiss the ticket. If you believe the officer's meter was faulty, you can request that the court test your windows with their own meter, but this is rare and usually unsuccessful.
