San Mateo, California
Drivers in San Mateo are subject to California's vehicle window tint rules, which set out how much light must pass through different windows. Understanding those rules before you choose a film keeps your car road legal and helps you get the look and comfort you want without a costly change of mind later.

Tint that falls outside California's limits can bring financial and legal consequences. A correction notice is a common outcome, and it usually means putting the glazing back within the legal limits and showing that the issue has been resolved.
Illegal film has to be removed before compliant film can go on, so the wrong shade often means paying twice. Very dark front glazing can also cut visibility at night. Confirming the limits before you book avoids both problems.
California sets tint limits by window position and by vehicle type, so a sedan and an SUV are not always treated the same way. The diagrams below outline the limits for passenger and multi-purpose vehicles. Visible light transmission describes how much light passes through the glazing, and it is separate from how much solar heat a film rejects, so a lighter film is not automatically a warmer one.
Passenger Vehicles
Passenger vehicles such as sedans and coupes have set limits for each window position, with the front glazing treated more strictly than the rear.
A non-reflective tint / sun strip, is allowed 4 inches from the top as long as it does not go past the AS-1 line on your windshield.
The California law allows 70% of light visibility for front side windows.
The California law allows any shade of light visibility for rear side windows.
The California law allows any shade of light in visibility for the rear window.
