Understanding California's tint limits keeps your car legal and your view clear. This guide covers how the rules apply to passenger and multi-purpose vehicles, what happens if film is too dark, and how to talk to an installer about a shade that works for you.

Film that falls outside California's limits can attract a citation. A fix-it ticket asks you to correct the problem and show proof that the vehicle now complies, which usually means having the film removed or replaced with a legal shade.
Correcting illegal tint means paying for removal on top of the original job, and often for new film in a legal shade. Choosing a compliant shade at the outset avoids that cost.
California sets separate expectations for passenger cars and for multi-purpose vehicles such as trucks, vans and SUVs. The tables below summarize how light transmission is treated on each window. Film choice and compliance are two different decisions: pick the film for the performance you want, then confirm the shade against the current rules.
Passenger Vehicles
For sedans and similar passenger cars, each window is treated separately, with the windshield and front side windows held to the tightest limits.
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.
