California Governor Expands Medical Exemption List for Tint

September 6th, 2017 by Katherine Coig

California Gov. Jerry Brown recently signed into law a bill introduced by Kevin McCarty allowing vehicle windows to be tinted at a lower visible light transmittance (VLT) than what’s currently allowed, if the driver has a signed certificate from a dermatologist stating the occupant cannot be exposed to ultraviolet rays. The state’s current law requires a minimum of 88-percent VLT. However, the exemption lowers the VLT to 70 percent.

According to the Assembly Floor Analysis, prior to the bill’s enactment, the state allowed for certain medical exemptions; however, the existing exemptions did not include diseases that cause “severe UV sensitivity.” Examples used to argue the case included lupus, which affects 1.5 million people throughout the U.S., and xeroderma pigmentosum, a rare genetic disorder which requires the afflicted to shield their entire bodies from UV light.

According to the law, the driver must also have a document provided by the film installer, in addition to the dermatologist’s note.

“The driver has in his or her possession, or within the vehicle, a certificate signed by the installing company certifying that the windows with the material installed meet the requirements of this subdivision and the certificate identifies the installing company and the material’s manufacturer by full name and street address, or, if the material was installed by the vehicle owner, a certificate signed by the material’s manufacturer certifying that the windows with the material installed according to manufacturer’s instructions meet the requirements of this subdivision and the certificate identifies the material’s manufacturer by full name and street address,” the bill states.

In addition, if the film bubbles or tears, the driver must have it removed or replaced.
