Window tint laws in California and Arizona

Window tint laws in California and Arizona

Posted: Updated:

Desert Southwest, June 15 -- If you have any doubt summer is here go sit in your car for a few minutes.  It's scorching.  Window tinting sounds like a great idea, but there are some restrictions you need to know about first.

Body shops all over the Desert Southwest have people lined up to get their windows tinted now that summer is here.  When it's placed on the windows of a car, the tint will block various kinds of light from entering the vehicle, either by absorption or reflection.  A car that is not tinted will allow 90 percent of natural light in to a vehicle.  But some state laws prohibit you from keeping cool.

In California you're not allowed to have window tint on the front windows or the windshield of the vehicle. But that's not the case in Arizona.  There are no regulations in either state about  having you're rear windows tinted.
