Understanding Tennessee Window Tint Law

Window tinting is a popular choice for many vehicle owners, offering benefits such as privacy, heat reduction, and protection from harmful UV rays. However, it is essential to understand the regulations surrounding window tinting to ensure compliance with the law. In this article, we will explore the Tennessee window tint law and provide you with the information you need to know.

Legal Tint Limits

Tennessee has specific regulations regarding the darkness of window tint on both cars and trucks. These regulations are measured in terms of Visible Light Transmission (VLT), which refers to the amount of light that can pass through the window. The lower the VLT percentage, the darker the tint.

For sedans, the front side windows must allow at least 35% of light to pass through, while the rear side windows and the rear window can have any darkness. This means that you can have darker tint on the rear windows and rear windshield, as long as the front side windows comply with the 35% VLT requirement.

For trucks, the front side windows must also have a VLT of at least 35%. However, there are no restrictions on the darkness of the rear side windows and the rear window for trucks. This means that you have more flexibility in choosing the level of darkness for these windows.

Medical Exemptions

Tennessee law allows for medical exemptions for window tint that is darker than the legal limits. To qualify for a medical exemption, you must have a medical condition that requires you to limit your exposure to sunlight. Examples of conditions that may qualify include lupus, melanoma, and other skin-related conditions.

If you believe you qualify for a medical exemption, you must obtain a certificate from a licensed physician stating the specific medical condition and the recommended level of tint darkness. This certificate must be carried in the vehicle at all times and presented to law enforcement upon request.

Enforcement and Penalties

Law enforcement officers in Tennessee are vigilant in enforcing window tint regulations. If you are found to be in violation of the window tint law, you may be subject to penalties, including fines and the requirement to remove or modify the tinted windows to comply with the law.

It is important to note that ignorance of the law is not a valid defense. Even if you recently purchased a vehicle with non-compliant window tint, it is your responsibility to rectify the situation to comply with the law.


Understanding the Tennessee window tint law is crucial for vehicle owners who are considering or already have tinted windows. By adhering to the legal limits and obtaining any necessary medical exemptions, you can enjoy the benefits of window tinting while staying within the boundaries of the law.

Remember to consult the specific regulations for your vehicle type to ensure compliance. If you have any doubts or questions, it is always best to seek advice from a knowledgeable professional or contact your local law enforcement agency for clarification.
