Under Tennessee tint laws, every side and rear window on a vehicle driven on public roads must allow at least 35% of visible light to pass through, and the windshield must let at least 70% of light through everywhere below the factory shade band. Violations are Class C misdemeanors carrying a fine of up to $50, and if an officer questions your windows, you are the one who has to prove the tint is legal.
How Dark Tint Can Legally Be
Tennessee measures darkness by Visible Light Transmission (VLT), the percentage of outside light that passes through the glass. Higher VLT means a lighter window. Tennessee Code 55-9-107 sets the floor at 35% VLT for every side window and every rear window after tint is applied.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows At 35%, the interior is still visible from outside during the day, which is what the statute is protecting: an officer’s ability to see into the vehicle on a stop.
The windshield is stricter. Aftermarket material cannot bring the windshield’s VLT below 70%, with one carve-out for the manufacturer’s standard shade band, meaning the factory-tinted strip across the top.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows If your windshield came with that band from the factory, it is legal. Adding aftermarket film below the band that drops VLT under 70% is not. Some online guides reference an “AS-1 line” or a five-inch strip; the Tennessee statute does not use those measures. The rule is the 70% floor.
Tennessee does not give SUVs, trucks, or vans a darker rear-window allowance. The statute applies the 35% VLT threshold to front door windows on “any motor vehicle of any kind.”1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows The one narrow allowance: if federal regulations permit a vehicle model to come from the factory with rear windows tinted below 35%, that factory glass stays legal. The allowance covers the factory glazing itself, not aftermarket film added on top of it.
Mirrored and Metallic Tint
Tennessee prohibits metallic and mirrored tint films because of the glare they throw at oncoming drivers. The statute does not set a numerical reflectivity cap the way it sets the 35% VLT threshold; instead, it bars the film type. If a product is marketed as chrome, mirror, or metallic finish, it is not legal here. Non-metallic carbon and ceramic films are not affected by this restriction.
Who Can Get an Exemption
Medical Exemptions
If ultraviolet light aggravates a medical condition, you can apply to use tint darker than 35% VLT. The statute does not name qualifying conditions. It covers any person whose condition is “adversely affected by ultraviolet light.”1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows Lupus, albinism, and severe photosensitivity disorders are common examples, but they are not the only ones considered.
To apply, submit a physician’s statement certifying the medical need, along with a copy of your vehicle registration and your driver’s license number, to the Department of Safety and Homeland Security at Driver.Improvement@tn.gov.2State of Tennessee. How Do I Obtain a Window Tint Exemption? The department’s medical review board evaluates the request and recommends the level of exemption. If approved, you receive a certificate or decal that must be displayed in the vehicle.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows
Vehicle Exemptions
Some vehicles are exempt from the 35% VLT requirement, but only for windows behind the front doors:
- Law enforcement vehicles with commercial or government service plates used for law enforcement purposes. The front door windows must still meet 35%.
- Vehicles registered in another state that comply with that state’s tint requirements.
- Vehicles owned or leased by licensed private investigators or investigation companies.
- Vehicle models that federal regulations permit to be factory-equipped with windows below 35% VLT.
Limousines and hearses are not specifically exempt under the Tennessee statute, despite what some online guides claim. And no exemption in any category removes the 35% requirement from the front door windows.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows
What Happens on a Traffic Stop
A POST-certified officer who reasonably believes your windows violate the tint law has probable cause to detain your vehicle for a field comparison test. The Commissioner of Safety sets the standardized method, which typically involves a tint meter pressed against the glass. Refusing the test is not an option. Refusal is itself a Class C misdemeanor, separate from any underlying tint violation.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows
One point catches drivers off guard: the burden of proof sits on the vehicle owner. Tennessee requires you to show the tint is legal, not the officer to show it isn’t.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows That is why the installer’s compliance label and receipt (covered below) matter well beyond the day of installation.
Penalties
Every violation of Tennessee’s tint law is a Class C misdemeanor. That includes driving with illegal tint, installing non-compliant film for profit, and refusing a field comparison test. The maximum penalty is a fine of up to $50, up to 30 days in jail, or both.3Justia. Tennessee Code 40-35-111 – Authorized Terms of Imprisonment and Fines for Misdemeanors Jail is not the practical outcome for a tint stop, but the misdemeanor classification means the offense is criminal and appears on your record rather than as a routine traffic ticket. You may also be required to remove or replace the film to avoid further citations.
Insurance and Civil Exposure
The criminal fine understates the real cost of illegal tint. If you are involved in a collision, your insurer may treat aftermarket tint as an undisclosed vehicle modification and exclude the tinted windows from a claim while still covering other repairs.
Civil liability reaches further. If reduced visibility through dark tint contributed to a crash, opposing counsel in a personal injury or wrongful death case can point to the illegal tint as evidence of negligence. Suits have been brought against both drivers and the shops that installed non-compliant film, on the theory that the installer failed to follow the law.
Why the Installer Label and Receipt Matter
Tennessee places compliance obligations on the installer as well as the owner. Anyone who installs tint for profit is a “professional installer” under the statute, and it is independently unlawful for that person to apply film that puts the vehicle out of compliance.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows Both you and the shop face potential penalties if the tint is illegal.
Every professional installer must affix an adhesive label to the lower right corner of the driver’s side window. The label carries the installer’s business name and the statement “Complies with Tennessee Code Annotated, § 55-9-107.” Size and style are set by the Commissioner of Safety.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows A vehicle with aftermarket tint and no label is a flag for any officer.
The installer must also give you a signed receipt with the date of installation, the vehicle’s make, model, paint color, and license plate number, a compliance statement, and instructions to keep the receipt with your registration.1Justia. Tennessee Code 55-9-107 – Tinted Motor Vehicle Windows Keep it. Given that the burden of proof is on you, the label on the window and the receipt in the glovebox are the documentation that resolves a stop quickly instead of turning it into a citation.
If you install film yourself, there is no professional label and no compliance receipt. You have no third-party documentation that the film meets the 35% threshold, and the absence alone invites scrutiny when an officer sees aftermarket tint with no sticker.
