Is 20% Tint Legal in Tennessee? VLT Laws Explained

Window tint laws in Tennessee are designed to balance driver safety, visibility, and personal preference. Violating tint regulations can result in fines, failed vehicle inspections, and the requirement to remove illegal tinting. Understanding what's allowed in your state helps you avoid these headaches while keeping your vehicle looking great.

Quick Reference Table

Understanding VLT (Visible Light Transmission)

VLT stands for Visible Light Transmission—it's the percentage of visible light that passes through your window tint. A 70% VLT tint, for example, allows 70% of light to pass through, meaning 30% is blocked. The higher the percentage, the lighter the tint; the lower the percentage, the darker it appears.

In Tennessee, the front windshield and front side windows have stricter VLT requirements (70%) compared to rear windows (35%). This tiered approach ensures drivers maintain clear visibility through the front of the vehicle while allowing darker tint for privacy in the rear. When shopping for tint, always ask your installer about VLT percentages to ensure compliance with state law.

Front Windshield Rules in Tennessee

Tennessee allows tinting on your front windshield, but only above the AS-1 line (the point where the windshield's upper edge meets the roof line). Any tint applied to the upper portion must be non-reflective and allow at least 70% of light to pass through.

This restriction exists because tint below the AS-1 line would obstruct the driver's view of the road and oncoming traffic. The AS-1 line is typically around 4-5 inches from the top of the windshield, though exact placement varies by vehicle model. Professional tint installers in Tennessee are familiar with these measurements and can apply compliant windshield tint safely.

Side Window Rules in Tennessee

Tennessee requires that both front side windows (driver and passenger) maintain a minimum VLT of 70%. This means no more than 30% of light can be blocked on either front window.

Many drivers find this requirement more restrictive than desired for privacy, but it's a compromise that ensures law enforcement and other motorists can see inside your vehicle. If you want darker tint, you'll need to apply it only to your rear side windows, which have more lenient requirements. Some drivers opt for 70% tint on the front and then darker tint (such as 35% or darker) on the rear for a graduated appearance.

Rear Window Rules in Tennessee

The rear window has more flexibility than the front windows. Tennessee allows a minimum VLT of 35% on your rear window, meaning you can go much darker in the back of your vehicle.

Many drivers take advantage of this rule by applying very dark tint—sometimes as dark as 5-15% VLT—to the rear window for maximum privacy. Vehicles with dual side mirrors are still required to follow the 35% minimum rule for rear windows; having dual mirrors does not exempt you from VLT restrictions. Rear side windows follow the same 35% minimum rule, allowing you to create a cohesive dark appearance on the rear half of your vehicle while maintaining front visibility.

Restricted Tint Colors in Tennessee

Tennessee does not prohibit specific tint colors like red, amber, or blue. However, any tint applied must be non-reflective, meaning it cannot have a mirror-like or metallic appearance. Reflective tints can cause glare and obstruct the view of other drivers, which is why the state bans them.

This rule applies to all windows, including the front windshield. When selecting tint at a shop, confirm with your installer that the product is non-reflective and compliant with Tennessee law. Most professional tint shops stock only compliant materials, but it's always good to ask.

Medical Exemptions for Window Tint in Tennessee

Tennessee does allow medical exemptions for window tinting under specific circumstances. Individuals with photosensitivity, lupus, or other medical conditions that make them sensitive to sunlight may qualify for a medical exemption that allows darker tint than normally permitted.

To obtain a medical exemption, you'll need a written statement from a licensed physician documenting your condition and recommending tint as a medical necessity. Submit this documentation to the Tennessee Department of Safety and Homeland Security along with your vehicle registration information. Once approved, you'll receive documentation to carry in your vehicle. Law enforcement will recognize your medical exemption if pulled over. The approval process typically takes 2-4 weeks.

Penalties for Illegal Tint in Tennessee

If stopped by law enforcement for illegal window tint, you may receive a citation. Tennessee treats window tint violations as a non-moving violation, typically resulting in a fine of $50 to $100 depending on the officer's discretion and your local jurisdiction.

In many cases, law enforcement will issue a "fix-it ticket," giving you a set timeframe (usually 10-30 days) to have the tint removed or corrected. If you bring proof of compliance to the issuing officer or courthouse, the citation may be dismissed. Vehicle inspection failures in Tennessee will also flag illegal tint—you won't pass inspection until the tint meets state standards. Removing or correcting non-compliant tint is usually faster and cheaper than paying fines and dealing with inspection failures.
