If a medical exemption is requested for someone other than the registered owner of the vehicle, please provide the following information about that person. In most cases, you will need to fill out a vehicle tint-waiver request form — or some form along those lines — depending on where you reside.The law provides an exemption for any person who, for medical reasons, must be shielded from direct sunlight. Window tint medical exemptions allow you to install darker tint on car windows. See all requirements for medical waivers, certificates and exceptions. We do not offer a window tint exemption. We only have a colorless sun screening waiver. I had to fill out the initial paperwork that I picked up at the Operator Control office portion of the DMV.
