Knowing the tint rules before film goes on the glass saves an expensive change of mind later. This guide covers how the limits are set, how they apply to different vehicle types, and how to choose a film and shade you're happy to drive with in West Chicago.

Tint that sits outside the legal limits can be dealt with at the roadside. Depending on the circumstances, that may mean a citation and a requirement to correct the film and show that the vehicle now complies. The practical cost is rarely just the penalty: it is the removal, the cleanup and then paying again for a film you could have chosen in the first place.
Taking film off is slower and messier than putting it on. The adhesive is built to stay put, so removal usually leaves residue that has to be worked off the glass, and the rear defroster lines can be damaged in the process. Choosing a legal shade at the outset avoids the whole job.
Tint limits in Illinois are set by vehicle category, and the windows are treated differently depending on where they sit on the car. Passenger vehicles and multi-purpose vehicles each have their own figures, expressed as visible light transmission, the amount of light that passes through the glass. The diagrams below show how those limits apply, window by window.
Passenger Vehicles
Sedans, coupes and similar cars are covered by the passenger vehicle rules, which set the permitted levels for the windshield, front side windows and rear glass.
A non-reflective tint / sun strip, is allowed 6 inches from the top as long as it does not go past the AS-1 line on your windshield.

Kepler film is made to hold its look on the car rather than fade into a purple haze a few summers in. Color stability, optical clarity and a clean edge at the glass all matter as much as the numbers on a spec sheet, because they are what you actually live with every day you drive. Ask your dealer about the specification and coverage that applies to the film you choose.
