Tennessee Window Tint Laws (2026): Legal VLT Limits
Tennessee Window Tint Laws (2026): Legal VLT Limits
In Tennessee, front side windows must allow at least 35% visible light transmission (VLT) for all vehicle types. For sedans, back side and rear windows must also meet the 35% minimum, but SUVs, vans, and other multipurpose vehicles may use any darkness on the windows behind the driver.
What is the legal tint limit in Tennessee?
Tennessee window tint law is governed by T.C.A. 55-9-107. The single most important number is 35% VLT for front side windows, which applies to every vehicle on Tennessee roads. A higher VLT percentage means lighter tint and more light passing through; a lower VLT percentage means darker tint and less light.
For the windows behind the driver, Tennessee draws a clear line between sedan-type vehicles and multipurpose vehicles. On sedans, the 35% VLT minimum applies to both back side windows and the rear window. On SUVs, vans, trucks, and other multipurpose vehicles, there is no VLT minimum on the windows behind the driver, meaning any darkness is legal.
| Window | Sedans (min. VLT) | SUVs / Vans / Multipurpose (min. VLT) |
|---|---|---|
| Front side windows | 35% | 35% |
| Back side windows | 35% | Any darkness |
| Rear window | 35% | Any darkness |
| Windshield | Non-reflective strip above AS-1 line only | Non-reflective strip above AS-1 line only |
If you drive an SUV or van, the practical effect is that you have significant flexibility on the rear passenger area. Many SUV owners in Tennessee run very dark or even limo-level tint (5% or less) on the rear glass, which is legal as long as the front side windows stay at 35% or lighter.
Windshield tint rules in Tennessee
Tennessee requires the main area of the windshield to allow more than 70% VLT at all times. The only exception is a non-reflective strip at the very top of the windshield, above the AS-1 line, which is the standard sun visor band most states permit. No tint may extend below the AS-1 line onto the primary driving field of the windshield.
Metallic or mirrored tint is prohibited on all windows under Tennessee law, including the windshield strip. The statute does not call out specific banned colors beyond the metallic and mirrored prohibition, but any film that gives the glass a chrome, mirror, or highly reflective appearance violates the law regardless of its VLT percentage.
The 70% threshold for the full windshield is worth noting if you are considering a clear UV-blocking film across the entire windshield. Any full-windshield film must still pass more than 70% of visible light to be legal.
Medical exemptions in Tennessee
Tennessee allows a medical exemption for darker tint. A licensed physician can certify that a driver or regular passenger has a medical condition requiring protection from sunlight, and that certification permits the installation of tint that is darker than the standard 35% limit.
If you qualify for an exemption, carry the physician's certification in the vehicle at all times. When stopped, presenting this documentation to an officer immediately explains why your windows appear to exceed the normal limits. The Tennessee Department of Safety handles driver services and can provide guidance on the formal documentation process.
Common conditions that qualify for medical exemptions include lupus, certain skin cancers, albinism, and photosensitivity disorders. Your physician must certify the medical necessity; a general request from a patient does not automatically qualify. Check with the Tennessee Department of Safety or a Tennessee attorney for the current form and requirements.
How tint is measured and certified in Tennessee
Tennessee law enforcement uses a VLT meter to test window tint during traffic stops. The officer measures the percentage of visible light passing through the glass, and if it falls below the legal limit, a citation can be issued.
An installer label is required on every vehicle with tinted windows. The sticker must appear in the lower-right corner of the driver's side window and must cite T.C.A. 55-9-107. The label identifies the installer and certifies that the film was installed to legal specifications. This sticker is your first line of defense at a traffic stop. A properly placed sticker from a licensed installer signals compliance even before a meter is used.
When choosing an installer, ask specifically whether they are familiar with T.C.A. 55-9-107 and whether they will provide the required compliance label. Keep your installer's receipt showing the VLT percentage of the film installed. If you are stopped and receive a citation you believe is in error, that paperwork and the sticker together form the basis of a challenge.
The Tennessee statute does not specify a published measurement tolerance, unlike South Dakota's broad plus or minus 9% or Alabama's plus or minus 3%. In practice, officers generally allow a small real-world variance for measurement equipment calibration, but there is no statutory protection for being slightly over the darkness limit.
Penalties for illegal tint in Tennessee
A violation of Tennessee's window tint law under T.C.A. 55-9-107 is a Class C misdemeanor. A Class C misdemeanor in Tennessee carries a maximum penalty of 30 days in jail and a fine of up to $50. In practice, tint violations are almost always resolved with a fine and a requirement to bring the vehicle into compliance. Jail time for a first-time tint offense is exceedingly rare.
If you are cited, you typically have the option to correct the violation (remove or replace the non-compliant tint) and present evidence of correction to the court, which may result in dismissal or reduction of the fine. Courts handle these corrections differently by county, so contacting the issuing court for their specific process is advisable.
Not having the required installer sticker can itself trigger a citation under the statute, even if the VLT of the film is technically legal. Make sure the label is present and readable at all times.
If you want to tint your windows in Tennessee
Here is how to get tint installed in Tennessee and stay on the right side of T.C.A. 55-9-107.
Confirm your vehicle type first. If you drive an SUV, van, or another multipurpose vehicle, you have maximum flexibility on the back side windows and rear window, and any darkness is legal behind the driver's position. Your front side windows still must meet the 35% minimum regardless of vehicle type.
For sedan owners, all four side windows and the rear window must meet the 35% threshold. Choosing a 35% film is legal, but a 40% film gives you a buffer in case of meter variation.
Ask your installer for the required T.C.A. 55-9-107 compliance sticker and make sure they affix it in the lower-right corner of the driver's window. If an installer does not know about the sticker requirement, find a different installer.
Keep a copy of the installation receipt with the film's VLT specs in the glove box. If you have a medical exemption, keep the physician certification there as well.
Avoid metallic or mirrored film on any window, including the windshield strip. Even if the film is dark enough to pass the VLT test, a mirrored appearance is a separate violation.
