Include skin cancer as medical condition that permits certain materials on motor vehicle windows and windshields.

This bill adds skin cancer to the list of medical conditions that allow drivers or passengers to apply for special window tinting on vehicles. It specifically includes "a history of, or a substantial risk of developing, skin cancer" as qualifying under existing rules for medical exemptions. Currently, people with conditions like lupus or light sensitivity could seek permission to use tinting materials that reduce sunlight exposure; this bill expands that exemption to cover skin cancer risks. The change requires the same application process: a doctor's certification and approval from the Motor Vehicle Commission.
