What Medical Conditions Qualify for a Window Tint Exemption? The DMV considers various medical conditions for window tint exemptions, including but not limited to lupus, porphyria, xeroderma pigmentosum, and severe drug photosensitivity.

California Window Tinting Laws. California window tint law restricts windshield tint on top 4 inches. Front side windows must have 70% light transmission or more. Back side windows and rear window may have any tint darkness.

For the front windshield, tint is restricted to the top four inches of the windshield. On the vehicle's front side windows, tint must allow for 70% light transmission, so 30% tint is the maximum. For the vehicle's side rear windows, any level of tint is allowed, and this applies to the rear windshield as well.

The first time a driver is pulled over for violating California's window tint laws, they will likely receive a warning. Officers often issue warnings for these traffic violations, informing the driver that they need to address the issue right away.
