Illinois window tint reference card

• Your film manufacturer’s certificate or installation receipt, kept in the glovebox. (Illinois does not require film manufacturers to certify their film for sale in the state.)
• Post-installation VLT reading receipt if you have one (tint shops will print it free on request).
• If you hold a Illinois medical tint exemption, carry the official permit, physician form, or ID card in the vehicle at all times.
• Know the ±3% meter tolerance. If your window reads 35% VLT or higher, a reading of (minimum − 3%) or higher is within tolerance. See our Illinois meter tolerance page.

• Confirm your vehicle’s classification (passenger car vs MPV/SUV) via the door-jamb label.
• Choose a VLT at or above the 35% VLT or higher minimum for front side windows.
• Verify the film meets the Illinois reflectivity cap.
• Use a manufacturer-certified installer (3M Pro Dealer, LLumar SelectPro, SunTek Pro Tint, or Solar Gard). See how to find a good tint shop.
• Require a printed post-install VLT reading for every window.
• Store the manufacturer certificate + installer warranty with vehicle registration.

A single-page, printed reference card in the glovebox is the cheapest insurance you can carry against a wrongful tint stop in Illinois. During a roadside conversation with an officer, being able to hand over a concise document that:

• Cites the current Illinois VLT minimums for your vehicle class,
• Lists the reflectivity cap,
• References the state statute or administrative code,
• Shows your film brand, VLT, and install date,

… accomplishes several things at once. It demonstrates that you understand the law, it narrows the question to a straightforward reading, and it gives the officer something to anchor their notes on. Many stops end in a warning once the officer sees that the driver has done their homework.

A complete glovebox tint-documentation kit for Illinois includes:

1. This reference card, printed single-sided on letter or A4 paper.
2. Your installer’s original invoice showing film brand, model, rated VLT for each window, and install date. This establishes what was installed and proves the work was done by a professional.
3. The manufacturer warranty certificate (3M, LLumar, SunTek, Solar Gard, XPEL, etc.). This lets the officer verify the film is a legitimate named product, not an uncertified import.
4. A copy of your most recent VLT meter reading if you have one — taken by the installer at install or by a tint shop any time the film was re-measured.
5. Medical exemption documentation, if applicable. Either the state-issued permit/sticker or the signed physician certification.
6. Vehicle registration and proof of insurance. Standard glovebox items, but confirm they are current and accessible.

Store all these documents in a single labeled envelope. If you are stopped, you hand the officer the envelope, not a stack of loose papers.

• After each state legislative session (January–June typically), check whether the Illinois tint statute has been amended. Our state pages are updated on a 6-month review cycle — the footer of your state page shows when it was last reviewed.
• After any new tint install or film replacement, re-print the card with the updated film brand, VLT, and install date.
• Annually on your inspection date (in states with annual inspection), print a fresh card while you are gathering the other documents for inspection.
• After you move or register the vehicle in a new state, print the new state’s reference card immediately — old cards become misleading the moment you cross state lines with updated plates.
