Window Tint Laws

How Dark Can Window Tint Be in Illinois?

The darkness of tint is measured by Visible Light Transmission percentage (VLT%). In Illinois, this percentage refers to percentage of visible light allowed in through the combination of film and the window.

Illinois Law Requires:

• Windshield Non-reflective tint is allowed on the top 6 inches of the windshield.
• Front Side Windows Must allow more than 35% of light in.
• Back Side Windows Must allow more than 35% of light in.
• Rear Window Must allow more than 35% of light in.

More Legal Combinations:

• 30-35% in the rear/up to 50% front
• If you have below 30% tint in the rear, you cannot have front tint.
• If you have an MPV, which include but are not limited to, SUVs, Station Wagons, minivans, Toasters, etc., and said MPV has factory installed privacy glass (smoked), you are allowed to have up to 50% tint in front.
