Illinois house bill 3325(actual house bill) has been heavily followed by Illinois car enthusiasts. While the new bill proposes some of the most stringent of regulations for window tinting, in my opinion it is a step in the right direction.
If you have tint darker than 30% on the rear, you will NOT be able to tint your front windows
If you have 35% on the rear section, you can also have 35% on the front doors, or if you go a touch darker in rear…30%, you are allowed 50% on the fronts
Suvs/Wagons/Vans with factory Privacy Tinting on the rear windows, only get to have 50% on the front windows

 

Whoa and i thought TX tint laws were messed up.
