These regulations mean that if you want darker-than-standard tint on your front side windows or other restricted areas, you may need an Ohio medical window tint exemption. ForeverTint helps simplify the process by connecting qualifying individuals with a licensed physician for evaluation and assisting with the medical affidavit required under Ohio Administrative Code 4501-41-05. Once approved, your documentation can be kept in your vehicle as proof of your legal Ohio window tint exemption.
