These restrictions mean that if you want darker-than-standard tint—especially on your windshield or front side windows—you must obtain approval through a Tennessee medical window tint exemption. Without state authorization, darker tint can result in citations. ForeverTint helps you determine if you qualify by connecting you with a licensed physician who understands Tennessee’s requirements, and if approved, you’ll receive the necessary medical documentation to submit to the state so you can legally request darker window tint under Tennessee law.
