Is 20% Tint Legal in Illinois? VLT Laws Explained
Window tint can enhance your vehicle's appearance and comfort, but Illinois has specific rules about how dark your windows can be. Breaking these laws can result in citations, fines, and failed vehicle inspections. Understanding Illinois tint regulations before you visit a shop ensures you stay compliant and avoid costly tickets.
Quick Reference Table
| Window | Legal VLT % | Notes |
|---|---|---|
| Front Windshield | 35% (top AS-1 line only) | Non-reflective only above the AS-1 line |
| Front Side Windows | 35% | Driver and passenger windows |
| Rear Side Windows | Any darkness | No limit on rear side windows |
| Rear Window | Any darkness | No limit on rear windshield |
Understanding VLT (Visible Light Transmission)
VLT percentage measures how much visible light passes through your window tint. If a tint has 35% VLT, it allows 35% of outside light to enter your vehicle, blocking 65%. The lower the percentage, the darker the tint. This matters because extremely dark tint affects visibility and safety for you and other drivers.
Illinois regulations focus on the front windows, where drivers need clear visibility. Your front windshield and front side windows have specific legal limits, while rear windows have no restrictions. This balances privacy and personalization with road safety requirements.
Front Windshield Rules in Illinois
Illinois allows a non-reflective tint on your front windshield, but only above the AS-1 line (the line where the windshield transitions from the metal frame to glass). This tinted area must have at least 35% VLT or greater. The AS-1 line is typically about 5-7 inches from the top of the windshield, allowing drivers an unobstructed view of the road and dashboard.
Many drivers install subtle tints in this upper section for appearance and a bit of heat reduction. Keep in mind that your windshield tint cannot be reflective—it should be matte or clear to prevent glare and maintain visibility for oncoming drivers.
Side Window Rules in Illinois
Your front side windows—both driver and passenger—must allow at least 35% of visible light through. This 35% VLT limit is moderate, allowing you to add noticeable tint while keeping the windshield area relatively bright. Many shops recommend 35% tint for front windows as a good balance between privacy, heat rejection, and visibility.
To answer the question directly: 20% tint is not legal on your front side windows in Illinois. Any tint darker than 35% VLT on front windows violates state law and can result in a citation. If you're considering 20% tint, you'll need to apply it only to rear windows where no VLT restrictions exist.
Rear Window Rules in Illinois
Illinois imposes no VLT restrictions on rear side windows or your rear windshield. You can legally apply tint as dark as you want—including limo tint or 5% VLT—on these windows. This is where darker tints become an option if you're looking for maximum privacy and heat rejection on your vehicle.
Many drivers choose to keep rear windows clear or lightly tinted for safety and visibility when reversing or backing up. However, the law allows complete freedom, so the choice is yours. Just ensure your front windows remain within the legal 35% limit.
Restricted Tint Colors in Illinois
Illinois does not explicitly ban specific tint colors like red or amber. However, your tint cannot be reflective on any window, and it must not significantly impair visibility. Reflective or mirror-like tints are illegal across all windows because they create glare and reduce visibility for other drivers.
Stick with standard tint colors: neutral grays, blacks, and browns. If you're uncertain whether a particular tint product is reflective, ask your installer—reputable shops know Illinois laws and will guide you toward compliant options.
Medical Exemptions in Illinois
Illinois does allow medical exemptions for window tint. If you have a medical condition requiring darker tint for sun sensitivity or other health reasons, you can apply for an exemption from the Illinois Secretary of State's office.
To obtain a medical exemption, you'll need documentation from a licensed healthcare provider stating your medical necessity for darker tint. Once approved, you'll receive a certificate to carry in your vehicle. This exemption allows you to exceed the normal 35% VLT limit on front windows. However, you must still comply with the basic structure of the law (no reflective tint, front windshield restrictions apply). Contact your local Secretary of State office or their website for the current application process and required medical documentation.
Penalties for Illegal Tint in Illinois
If you're stopped with illegal window tint, you'll typically receive a citation. Illinois treats tint violations as moving violations, and fines can range from $100 to $500 depending on the severity and your driving record. A first offense is often issued as a "fix-it" ticket, giving you time to remove or adjust the tint and have it inspected by law enforcement to clear the violation.
Failing to address an illegal tint citation can result in points on your driving record and increased insurance premiums. Additionally, your vehicle may fail its state inspection if the windows don't meet legal requirements. It's much easier and cheaper to get compliant tint installed correctly the first time than to deal with citations and inspection failures.
