Fountain Valley, California
Tint compliance is worth understanding before any film goes on your car. California sets the limits that apply in Fountain Valley, and staying within them keeps your visibility good and your vehicle clear of avoidable trouble.

Driving with film that falls outside the California limits can lead to a citation and the cost of putting it right. A fix-it ticket means correcting the tint and showing that the vehicle now complies, so it's far cheaper to get the shade right the first time.
Removing film is slow work. Adhesive clings to the glass, and defroster lines on rear windows can be damaged if film is pulled away carelessly.
Tint rules in California are written around vehicle type, with separate expectations for passenger cars and for multi-purpose vehicles. The diagrams below set out how the limits are applied window by window, so you can see where a darker film is treated differently from the windshield or front sides. Remember that visible light transmission describes how much light passes through the glass; it is a measure of shade, not of how much solar heat a film rejects. Two films at the same shade can perform very differently, which is why it pays to compare the exact film and shade with your installer.
Passenger Vehicles
For passenger cars, including convertibles, the limits vary by window position, as set out here.
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.
