State

Your tint's VLT (optional)

VLT (visible light transmission) is the share of light the film lets through; a lower number is darker. It is printed on the film packaging or your installation receipt. Leave it blank to just read the limits.

Illinois legal tint limit, window by window

Front side windows

35% or 50% (two options)

Two options: (1) front sides ≥50% if no window behind the driver is below 30%; or (2) front sides ≥35% if no window behind the driver is below 35%. 5% metering variance..

Back side windows

Any darkness

No flat floor, the rear-window tint level selects the front option (≥30% for Option 1, ≥35% for Option 2).

Rear window

Any darkness

No flat floor; an obscured rear window is compliant if the vehicle has conforming side mirrors on both sides.

Windshield

Top 6 in, nonreflective

Nonreflective tinted film only along the top, extending no more than 6 inches down.

Medical exemption

Administered by the Secretary of State: a physician-certified statement carried in the vehicle, renewed every 4 years, with a copy filed with the SoS; the vehicle displays a distinctive Window Tint license plate (§3-412(k)). Form VSD 704. Statutory conditions include lupus, disseminated superficial actinic porokeratosis, albinism, and TBI light-sensitivity; conditions treatable with sunglasses do not qualify.

Penalty

First offense: petty offense, $50–$500. Second or subsequent: Class C misdemeanor, $100–$500 (the section sets its own range). Windows must be brought into compliance.

Tint-meter tolerance

5% variance for law-enforcement metering

Enter your film's VLT above to check it against each Illinois window limit, or read the limits as they stand.

The two front columns are the two statutory options. A window darker than 35% behind the driver leaves no compliant front-window option; an obscured rear window itself is allowed with conforming dual side mirrors (12-503(e)). Law-enforcement meters observe a 5% variance.

Film is sold by its own VLT, but police measure the installed darkness: the film combined with your factory glass, which reads darker than the film alone. These are the Illinois figures stated as information, not a determination about any stop or ticket.

Informational only, not legal advice. Reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. See the full rules, the exemption steps, and the citations on the Illinois window tint reference, cited to 625 ILCS 5/12-503.

How the Illinois tint rules work

Illinois does not have one front-window number; it has a trade-off. Go darker in back (down to 30%) and your front doors must stay at 50% or lighter; keep everything behind the driver at 35% or lighter and your front doors may go down to 35%. Police meters get a 5% grace, and repeat violations escalate from a petty offense to a Class C misdemeanor.

This checker applies the Illinois figures to the VLT you enter. It is informational only and not legal advice: reflectivity limits, color bans, and vehicle-class exceptions can change the answer for a specific car. For the full rules, the shades table, and the citations, see the Illinois window tint reference, cited to 625 ILCS 5/12-503.
