Illinois Tint Laws

Illinois tint laws were enacted relatively recently in the scheme of things, having been put in place in 2009. While rules governing how dark window tint can be and on what windows it can be placed have not changed significantly since that year, they do change from time to time, so it’s a good idea to check in on current window tint rules before any window film application.

The main factor that determines if window tint is legal or not in Illinois is its VLT percent, or visible light transmission percent, shortened to VLT. VLT concerns how much visible light passes through window film, and the more of it the clearer the window. So a window rated at 99% VLT looks almost completely clear, while a window with a 1% VLT looks completely opaque from outside the vehicle.

Note that Illinois window tint law does not allow for any metallic and reflective window tinting on cars, so even a tint that is permissible based on visible light transmission may still be illegal under state tinting laws.

As the rules about window tint in Illinois are different for various parts of a vehicle and for different types of vehicle, we will look at cars separately from trucks, vans, and SUVs, and we’ll break down each window individually.

% of Tint or Visible light transmission (VLT) is the measurement used to assess the amount of light passing through a piece of glass. This is the percent of visible light that passes through the film and glass to give you a net transmission percentage. The lower the VLT%, the darker the window.

Law Enforcement uses a tint meter which measures the Visible Light Transmittance (VLT) of window film and glass for illegal tint. 

Windshield: Several states allow medical exemptions for drivers or passengers who frequently travel in the vehicle. These exemptions usually require a licensed physician in that state to sign a waiver. Please visit your states .gov site for details. 

AS-1 Line: This is the line extending from the letters AS-1, found on most motor vehicle windshields, running parallel to the top of the windshield.

If you’re driving a truck or SUV built in the last decade, chances are it’s equipped with factory tinted glass on all windows behind the front doors.

Many owners of vehicles like this often choose to only have the front windows tinted to match the back because they believe that they are already set with the rear windows.

UV Protection

While this factory tint improves the looks of the vehicle, and offers rear passengers some privacy, it does very little to help reduce the heat entering through the glass or protect them from the sun’s harmful UV rays. 

Heat Rejection

The same also goes for heat rejection. Some assume that the level of heat rejection they will on the front glass is already present in the rear glass because of the factory tint. Nothing can be further from the truth. Other than having the tinted look, these windows do very little to stop the heat.
