In California, there are specific laws regarding the amount of tinting that is allowed on automotive windows. These regulations are in place for safety reasons, to ensure that drivers have sufficient visibility while operating their vehicles.
Here are the key points of California's automotive window tinting laws to consider when developing a plan to upgrade your vehicle.
Windshield Rules and Regulations: The windshield can have a tinted strip along the top, but it must not extend lower than the AS-1 line. This line is located at the top of the windshield and is marked by the manufacturer.
Front Side Windows Rules and Regulations: The front side windows (driver's and passenger's sides) must allow at least 70% of outside light to pass through. This means that the tint cannot be darker than 70%. However, medical exemptions are allowed, which allow drivers with certain medical conditions to use darker VLTs.
Back Side and Rear Window Rules and Regulations: The back side windows and rear windshield can be tinted as dark as desired, as long as the vehicle has side mirrors that provide a view behind the car. If the back side windows are tinted, the front side windows must also allow at least 70% of outside light to pass through.
Reflective tint is not permitted in California. Amber, blue, and red is restricted on all windows. These regulations apply to all types of vehicles, including cars, SUVs, trucks, and vans. If you need clarification on whether your vehicle's window tinting is legal, it's always best to check with your local law enforcement agency or an experienced automotive window tinting professional.
