Know The Legal Limits:
Car Window Tinting Laws
Every states’ car window tinting laws are different.
My goal is that you can find the current legal limit for the state in question by focusing on the areas that will most concern you. The resource on which we rely whenever we need to check window tinting laws is a chart published by the IWFA (International Window Film Association).
What does VLT% mean?
There are many different reasons one chooses to tint their vehicle. One of the main factors is privacy which is measured by VLT% (Visible Light Transmission%). It is important to understand VLT% because the window film industry uses this measurement to name their products. For example, Carbon 5, means 5% VLT (95% of the visible light is blocked). Understanding car window tinting laws should help consumers to ensure their vehicle is compliant.
How to read the chart.
When viewing the chart focus on the columns under the ‘visible light transmission’, these numbers are the legal limits. In Arizona the legal limit for your front side driver/passenger (F.SIDE) windows is 33%. There are no restrictions for the rear side windows or back-glass. The column labeled ‘Windshield’ refers to the visor strip which can be installed down to the AS1 marker stamped on the glass.
