Tennessee's Legal Window Tint Limits by Window Type
Tennessee law sets specific darkness limits for each window on your vehicle, measured as Visible Light Transmission (VLT) — the percentage of light allowed through the tint. The state does not ban tint outright, but the limits are strict and vary depending on which windows you tint.
For the windshield, you may tint only the top 6 inches with any darkness level. The rest of the windshield must remain clear. For the front side windows (driver and passenger), tint must allow at least 70% of light through — meaning no darker than 30% VLT. The rear side windows and rear window have no darkness limit; you can tint them as dark as you want, including limo tint or full black.
Tennessee does not require you to tint your windows at all. The limits explore only if you choose to do so. If your tint is darker than the law allows on front windows, law enforcement can stop you, and you may face a citation and be ordered to remove or lighten the tint.
Key Takeaways
- Front side windows must allow at least 70% light through (no darker than 30% VLT); rear windows have no darkness limit.
- Only the top 6 inches of the windshield may be tinted, and the rest must remain clear.
- Tennessee has no medical exemption program for darker tint, even with a doctor's note.
- A tint violation is typically a non-moving citation, but you must remove or lighten the tint to resolve it.
- Tint shops in Tennessee are not regulated by the state, so darkness accuracy depends on the shop's equipment and honesty.
How VLT Percentage Works and What It Means
VLT is measured in a lab using a light meter and a standard light source. A tint with 70% VLT lets 70% of light pass through; a tint with 30% VLT lets only 30% through and appears much darker. The darker the tint, the lower the VLT number.
When a shop applies tint, they should measure the darkness with a light meter to confirm it meets the law. However, Tennessee does not require shops to do this, and many do not. If you buy tint that the shop claims is 30% but is actually darker, you could be stopped and cited. The burden is on you to verify the darkness before you drive.
You can buy a handheld VLT meter online for $30 to $100 and test your tint yourself after installation. This is the only way to be certain your tint is legal, since shop claims are not always accurate and the state does not inspect or certify tint work.
Medical Exemptions and Special Circumstances
Tennessee does not have a medical exemption program for window tint. Even if you have a documented skin condition, light sensitivity, or other medical reason for darker tint, the state law does not allow you to exceed the 30% VLT limit on front windows.
Some states — including Alabama, Georgia, and Florida — do offer medical exemptions with a signed physician's statement and a special permit. Tennessee is not one of them. If you need darker tint for medical reasons, your only legal option in Tennessee is to tint only the rear windows, which have no limit.
If you are stopped with tint darker than 30% on front windows and claim a medical reason, the officer is not required to accept that as a defense. You would need to fight the citation in court and present medical evidence, but the law itself does not recognize a medical exemption, so the outcome is uncertain.
What Happens If You Are Cited for Illegal Tint
A window tint violation in Tennessee is typically a non-moving citation, similar to a broken taillight. The fine varies by county and municipality but is usually between $50 and $150. The citation does not add points to your driving record in most cases, but you are required by law to remove or lighten the tint within a set time frame — usually 10 to 30 days, depending on the officer's order.
If you do not comply, the officer can stop you again and issue a second citation. Repeated violations can result in higher fines and may eventually affect your vehicle registration renewal. Some counties allow you to show proof of tint removal or lightening to dismiss the citation; others require you to have the work done and inspected by law enforcement or a shop.
You have the right to contest the citation in traffic court. If you believe the tint is legal, you can request that the officer or the court measure it with a light meter. Bring documentation of the VLT percentage from your tint shop, or bring your own meter as evidence.
Tint Shop Standards and Your Responsibility
Tennessee does not license, regulate, or inspect window tint shops. Any business can offer tinting services without state oversight, training requirements, or accountability for accuracy. This means the quality and legality of the work depends entirely on the individual shop's standards and honesty.
Before you have tint installed, ask the shop whether they measure darkness with a light meter and whether they may provide the tint will be legal. Get the VLT percentage in writing. After installation, test the tint yourself with a handheld meter or ask the shop to test it in front of you. If the tint is darker than promised, ask them to lighten it or remove it and reapply.
If a shop installs illegal tint and you are cited, the shop is not liable. You are the vehicle owner and are responsible for the tint on your car, regardless of who installed it. Choose a shop with good reviews and a clear policy on measuring and guaranteeing legal darkness.
Differences Between Tennessee and Neighboring States
Tennessee's tint law is stricter than some neighboring states but looser than others. Kentucky allows 35% VLT on front windows and has a medical exemption program. Virginia allows 50% VLT on front windows. North Carolina allows 35% VLT on front windows and also has a medical exemption. Georgia allows 32% VLT on front windows and offers a medical exemption with a permit.
Alabama and Mississippi are closer to Tennessee: Alabama allows 32% VLT on front windows with a medical exemption, and Mississippi allows 28% VLT on front windows with no exemption. If you travel across state lines with your vehicle, your tint may be legal in Tennessee but illegal in a neighboring state, or vice versa. Check the law in any state where you plan to drive regularly.
How to Stay Compliant When Tinting Your Windows
If you want to tint your windows legally in Tennessee, follow these steps. First, decide which windows you want to tint. If you want dark tint, tint only the rear windows and rear window, which have no limit. If you want to tint the front side windows, choose a darkness no darker than 30% VLT.
Second, find a reputable tint shop and ask them to measure the darkness with a light meter before and after installation. Request the VLT percentage in writing. Third, after installation, test the tint yourself with a handheld meter or ask the shop to test it again in front of you. If it is darker than 30% on front windows, ask them to lighten it when ready.
Fourth, keep the receipt and any documentation of the VLT percentage. If you are stopped and cited, this documentation may help you contest the citation or prove the tint was legal at the time of installation. Fifth, if you are cited and the tint is found to be illegal, remove or lighten it promptly and keep proof of the work to show the officer or the court.

How do I know if my tint is legal?
The only reliable way is to measure it with a light meter that reads VLT percentage. Front side windows must allow at least 70% light through (30% VLT or lighter). Rear windows have no limit. Ask your tint shop to measure it, or buy a handheld meter for $30 to $100 and test it yourself.
What if I was tinted in another state and now live in Tennessee?
If your tint is darker than 30% VLT on front windows, it is illegal in Tennessee, even if it was legal where you had it installed. You must remove or lighten it to comply with Tennessee law. You cannot claim it was legal elsewhere as a defense.
