Tinting of front windows is legal in california, the law says 70% visible light must pass through. When I got mine done a long time ago, 50% was legal. 70% tint is not dark at all.....
Still plan to do mine 35% though
This general statement about California law is wrong. The relevant provisions of the California Vehicle Code make it clear as mud, but as I interpret it, this is the law in California:
Rule 1: No one may place "any object or material upon the windshield or side or rear windows" of a motor vehicle in California. Cal. Veh. Code § 26708(a)(1). So start with the proposition that sticking anything to your windows is entirely illegal. This is why windshield-mounted radar detectors and GPS devices are illegal in California.
Rule 2: Rule 1 doesn't apply to side windows to the rear of the driver. Cal. Veh. Code § 26708(b)(4). So applying both Rule 1 and Rule 2, it's now legal to stick tint film of any opacity on all side windows to the rear of the driver, and your kid can put up stickers in the minivan to their hearts' content.
Rule 3: Rule 1 doesn't apply to the rear window IF the car is equipped with two side mirrors. Cal. Veh. Code § 26708(b)(8). Applying Rules 1, 2 and 3 to all modern cars, it's now legal to apply window tint film of any opacity to your rear window(s).
Rule 4: Rule 1 doesn't apply to "
un screening devices meeting the requirements of Section 26708.2," that are accompanied by a doctor's note of medical necessity, AND that are removed during times of darkness. Cal. Veh. Code § 26708(b)(10). Hey, good luck with that, but that gets me nowhere.
Rule 5: Rule 1 doesn't apply to "transparent material" affixed to the topmost portion of the front windshield if it meets certain requirements. Cal. Veh. Code § 26708(c). Meh.
Rule 6: Rule 1 doesn't apply to pre-tinted safety glass (as opposed to tint film). Cal. Veh. Code § 26708.5(b). The lawyer in me wants to say, "Duh, glass that's pre-tinted doesn't have anything affixed to it within the meaning of Section 26708(a) in the first place."
Rule 7: Drum roll, please . . . Rule 1 doesn't apply to "clear, colorless, and transparent material" that is installed, affixed, or applied to the front side windows IF AND ONLY IF five conditions are met, the fourth of which is the installer's certification that it meets all requirements of subsection (d). Cal. Veh. Code § 26708(d). Basically, it allows material that blocks UV-A rays, if the installer can certify that it is "clear, colorless and transparent," that the film itself blocks only 12% of visible rays; that the film plus any pre-existing tint in the underlying glass together block only 30% of rays, etc. Aha, so here's where the rabbit goes into the hat -- what window tint is "clear, colorless and transparent"? What is the pre-existing tint value of your car's front side windows before the material is applied? Which installers will issue the required certificates? And who has the time to explain this all to the cop who's writing the ticket?
Rule 8: The only exceptions to the "no tint film" rules are those established by subsections (b), (c) and (d) of Section 26708. Cal. Veh. Code § 26708.5(a).
Ta-da!
So what was wrong with the original post? First, you need to carry the certificate in the glovebox. Second, you can only get to the OP's promise of 70% of visible light transference if you combine the maximum 12% film with a pre-existing window that is already effectively an 18% tint before the application of any film. You can't just slap on a 70% VLT tint. You have to slap on a 88% VLT tint, and if there was some darkness to the window to start with, congratulations but don't exceed 70% VLT total; if not, you get what you get and you don't throw a fit.
