Motor Vehicles - Enhanced Tinted Windows - Medical Exemption

HB 1507 allows out-of-state physicians licensed to practice medicine to issue medical exemption certifications for vehicles with tinted windows darker than Maryland's standard 35% light transmittance requirement. It removes the previous 2-year expiration limit for these exemptions, making them valid indefinitely for permanent medical conditions (like photosensitivity disorders). This directly affects Maryland residents requiring dark window tint for medical reasons, who previously needed in-state physician certifications with time limits. The bill does not change the 35% light transmittance rule itself, only the process for obtaining medical exemptions.
