Tennessee Window Tint Laws: Complete Legal Guide

Window tinting is a popular upgrade for vehicles in Tennessee, offering privacy, UV protection, and cooler interiors. However, Tennessee has specific window tint laws that every driver must follow, and violations can result in fines and failed vehicle inspections. Understanding these regulations before you tint your windows will help you stay compliant and avoid costly tickets.

Quick Reference Table

Understanding VLT (Visible Light Transmission)

VLT stands for Visible Light Transmission, and it's the key measurement that determines how dark your window tint can be. VLT is expressed as a percentage—the higher the number, the more light passes through the tint, making it lighter. For example, 70% VLT means 70% of visible light passes through the tint, while 20% VLT is much darker and blocks most light.

To measure VLT, manufacturers shine light through the tinted window and measure how much light comes through on the other side. This percentage is what Tennessee law enforcement uses when checking tint compliance. If your tint blocks more light than state law allows, you could receive a citation.

Front Windshield Rules

Tennessee law allows non-reflective tint on the front windshield, but only above the AS-1 line (the manufacturer's recommended line that typically runs across the upper portion of the windshield). This tint cannot exceed 70% VLT, meaning it must allow at least 70% of outside light to pass through.

The restriction above the AS-1 line exists because it preserves driver visibility—the lower part of your windshield must remain completely clear. Even though modern windshields often include a tinted band at the top from the factory, aftermarket tint must stay above that AS-1 line. Reflective or metallic tints are not permitted on the windshield in Tennessee.

Side Window Rules

Tennessee distinguishes between front and rear side windows. Your front driver and passenger windows (front side windows) are restricted to 35% VLT or lighter. This means these windows must allow at least 35% of light through, which is relatively dark but still transparent enough to see inside the vehicle.

The 35% limit on front side windows applies equally to both the driver and passenger windows—there's no special exception for drivers. This requirement exists for safety and law enforcement visibility during traffic stops. Many drivers choose this as the darkness level for their entire vehicle when they want a uniform look.

Rear Window Rules

Tennessee has no restrictions on rear window tinting. You can apply any darkness of tint to your rear side windows and rear window—even limo tint (5% VLT or lower) is completely legal. This is one area where Tennessee is relatively permissive compared to some other states.

Keep in mind that vehicles with dual side mirrors (exterior mirrors on both sides) have no additional exemptions or restrictions. The rear window darkness restriction is simply not enforced in Tennessee, so this is where many drivers choose to go darker for maximum privacy in the back of their vehicle.

Restricted Colors

Tennessee does not specifically ban red or amber tint colors in its window tinting statute. However, while colored tints may be legal, law enforcement may cite you under other vehicle lighting codes if your tint significantly alters the appearance of your vehicle's lights or creates a safety concern. The safest choice is neutral gray or carbon tint for all windows.

If you're considering any specialty colored tint, it's wise to check with a local shop familiar with Tennessee enforcement practices. What's technically legal may still attract unwanted attention from officers.

Medical Exemptions

Tennessee does allow medical exemptions for window tinting that would otherwise violate state law. If you have a documented medical condition such as lupus, photosensitivity, severe sun allergies, or other light-sensitive conditions, you may be eligible for an exemption permit.

To obtain a medical exemption, you'll need to submit a written statement from a licensed physician describing your condition and recommending darker window tint as a necessary treatment. Contact the Tennessee Department of Safety and Homeland Security for the specific application process and required documentation. Once approved, your exemption permit allows you to exceed standard tint darkness limits, but you should keep your exemption documentation in your vehicle at all times.

Penalties for Illegal Tint

Illegal window tint in Tennessee is typically cited as a non-moving violation and considered a Class C misdemeanor. A first offense can result in a fine of $50 to $150, plus court costs. If you receive a citation, you'll usually be given an opportunity to remove or modify your tint and present proof of correction (often called a "fix-it ticket").

Tennessee requires an annual vehicle inspection, and illegal window tint will cause your vehicle to fail inspection. You cannot renew your vehicle registration until you correct the tint issue. If you're pulled over and cited for tint, the most cost-effective solution is to have it removed or corrected by a professional tinting shop immediately and request a re-inspection.
