Can I put after-market tinting on the windows of my vehicle?
The main requirements for legal window tinting in California are:
1. The windshield and front driver’s side and passenger’s side windows cannot receive any aftermarket tinting.
2. If the rear window of a vehicle is tinted, the vehicle must have outside rearview mirrors on both sides.
The law prohibits any person from driving any motor vehicle with any object or material placed, displayed, installed, affixed, or applied upon the windshield or side or rear windows, with certain limited exceptions.
However, legislation signed into law effective January 1, 1999, exempts from the above prohibition specified clear, colorless, and transparent material that is installed, affixed, or applied to the front driver and passenger side windows for the specific purpose of reducing ultraviolet rays.
This legislation allow you to install window tint on the driver and passenger providing that it is clear and does not block more than 30% of the sunlight after it is installed on your car. There are several window film manufacturers that make a film that will meet this law. However, most of them do not meet the initial guidelines listed in the law. The law say that the film must me atleast 88% VLT prior to installation. But once it is installed in your car who cares right?
I have found that most CHP officers are not aware of the 1999 change in the law and will therefore tell you that you can not have any window tint in the driver and passenger.
I have found that most people want to go darker than the legal. I recommend 50%(which is still fairly clear) or 30-35%( a nice light shade)
these shades although not legal, seem to be very acceptable to CHP. They will usually let you get away with a little as long as they can clearly see through the driver and passenger windows.
