Frankfort, Illinois
Driving in Frankfort means meeting the same vehicle tint rules that apply across Illinois. Knowing what the law allows before film goes on the glass keeps your car road legal, protects your view at night and saves the cost of stripping film that should never have been fitted.

Film that sits outside the Illinois limits can turn into a fine and time spent putting it right. Enforcement usually begins with a traffic stop, and a fix-it ticket asks you to correct the film and then show that the vehicle complies.
Window film adhesive is made to stay put, so removal is slow work. Rushed stripping leaves glue on the glass and can lift the defroster lines on a rear screen. Choosing a legal shade first avoids paying for the job twice.
Illinois sets its tint limits by window position and by vehicle category, so the rules that cover a sedan are not always the rules that cover an SUV or van. The summaries below show how the limits are structured for each type of vehicle, and are a starting point for a conversation with your installer rather than a substitute for the current state rules.
Passenger Vehicles
Passenger vehicles, including sedans and coupes, have tint levels set window by window, from the strip at the top of the windshield through to the 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.
The Illinois law allows 50% of light visibility for front side windows.
The Illinois law allows 35% of light visibility for rear side windows.
The Illinois law allows 35% of light in visibility for the rear window.

Darker does not automatically mean cooler. Kepler IR and IR+ are nano-ceramic films built to work on infrared heat, so lighter shades are worth considering. Visible light transmission is separate from solar heat performance, so compare the exact film and shade, then check it against the Illinois limits.
