Understanding the window tint laws in the state where you live is important. Every state has different rules and regulations, and staying informed of your state’s window laws can help you avoid fees and other penalties. If you’re an Illinois resident, check out the window tint laws in your state below:


Window Tint Reflection in Illinois


Window tint is a useful mechanism for reducing glare and heat by reflecting incoming light. However, Illinois law limits how much reflection your window tint can have. Here’s what you need to know about Illinois’ window tint reflection regulations: 


Permitted Tint Reflection for SUVs and Vans


Front side windows: Windows must be non-reflective.

Back side windows: Windows must be non-reflective.

Front side windows: Windows must be non-reflective.

Back side windows: Windows must be non-reflective.


Window Tint Darkness in Illinois


Illinois regulates how dark the tint on your vehicle windows can be based on a measurement called Visual Light Transmission, or VLT. VLT is the percentage of visible light allowed through your car windows. The permitted VLT in Illinois depends on the type of vehicle that you drive. Here’s what you need to know:

Windshield: Non-reflective tint is only permitted on the top 6 inches of the windshield.

In addition to these laws, Illinois has several other tint darkness laws to know about:

All windows can have up to 35% VLT except the windshield.

Front side windows can have up to 50% VLT, given that the front side windows are not tinted.

If driving a vehicle with factory-installed window tint on any of the back windows, the front side windows must have more than 50% VLT.
