Illinois Window Tint Law 2025 – Legal Tint Percentage Guide

If you live in the Land of Lincoln, you might want to tint your car windows. Dark windows keep your car cool. They also give you privacy and make your car look great. However, you must follow the window tint law Illinois to avoid getting a ticket.

At Legal case news, we want to help you stay safe and legal. The rules for window tinting can be a bit confusing. Some rules are for small cars, and others are for large SUVs. This guide will explain the illinois window tint law in simple terms so you can drive without worry.

What Is Window Tint and Why Does It Matter?

Window tint is a thin film applied to vehicle glass. It blocks sunlight, reduces heat, and provides privacy. However, tint that’s too dark creates safety concerns. Police officers need to see inside vehicles during traffic stops. Drivers need clear visibility, especially at night.

Illinois has strict rules about how dark your window tint can be. These laws exist to balance driver preferences with public safety needs.

Understanding Tint Percentage Measurements

Window tint darkness is measured by Visible Light Transmission (VLT). This percentage shows how much light passes through the window. A higher VLT percentage means more light gets through, making the window lighter. A lower VLT percentage means less light passes through, making the window darker.

For example:

70% VLT allows 70% of light to pass through (lighter tint)
35% VLT allows 35% of light to pass through (medium tint)
5% VLT allows only 5% of light to pass through (very dark tint)

Illinois Window Tint Law: The Basic Rules

The illinois window tint law sets different limits for different windows on your vehicle. These rules apply to passenger cars, SUVs, and vans.

Passenger Cars (Sedans)

Windshield:

Only non-reflective tint is allowed on the top 6 inches
The rest of the windshield cannot have tint

Front Side Windows:

Must allow more than 35% of light in
This is the most important rule drivers need to follow

Back Side Windows:

Must allow more than 35% of light in
Same requirement as front windows

Rear Window:

Must allow more than 35% of light in
If tinted, you must have dual side mirrors

SUVs and Vans (Multi-Purpose Vehicles)

Windshield:

Only non-reflective tint allowed on top 6 inches
No tint on the remaining windshield area

Front Side Windows:

Must allow more than 35% of light in
This matches the sedan requirement

Back Side Windows:

Must allow more than 50% of light in
Slightly lighter than sedans

Rear Window:

Must allow more than 50% of light in
Dual side mirrors required if tinted

Tint Reflection Rules in Illinois

The illinois car window tint law also controls how reflective or mirror-like your tint can be. Highly reflective tint can blind other drivers, creating dangerous situations.

For All Vehicles:

Front side windows cannot have reflective or mirrored tint
Back side windows cannot have reflective or mirrored tint
Metallic or mirrored appearances are prohibited

Medical Exemptions Under Illinois Law

Some people have medical conditions that require extra protection from sunlight. The window tint law in illinois allows exemptions for these situations.

Who Qualifies:

People with photosensitivity disorders
Individuals with lupus or similar conditions
Anyone with a doctor-verified medical need

How to Get an Exemption:

Obtain written documentation from a licensed physician
The letter must explain your medical condition
Keep this documentation in your vehicle at all times
Show it to police if stopped

Medical exemptions allow darker tint than standard limits. However, you still cannot have completely blacked-out windows. Law enforcement must be able to see inside the vehicle for safety reasons.

Colors and Restrictions

Illinois law doesn’t ban specific tint colors. However, some colors may attract unwanted attention from law enforcement. Red and amber tints can be confused with emergency vehicle lights.

Recommended Approach:

Stick with neutral colors (black, gray, or slight blue)
Avoid colors that mimic emergency vehicles
Choose professional-grade film from reputable installers

Penalties for Violating Window Tint Laws

Breaking the illinois front window tint law results in consequences. While not the most serious traffic violation, illegal tint can cause problems.

Possible Penalties Include:

Traffic citation and fine (typically $50-$200)
Required removal of illegal tint
Failed vehicle inspection
Additional scrutiny during future traffic stops

Police officers can use tint meters to measure your VLT percentage during stops. These devices provide accurate readings. Arguing about tint darkness rarely works when an officer has measurement data.

We recommend consulting with local law enforcement or a professional tint installer if you have questions about specific situations. Legal Case Newz provides general guidance, but individual circumstances may vary.

Choosing a Professional Tint Installer

Working with experienced professionals helps you stay within legal limits. Quality installers know the illinois window tint law 2025 requirements and use proper measurement tools.

What to Look For:

Installers who guarantee legal compliance
Written warranties on materials and installation
Use of quality films from known manufacturers
References from previous customers
Membership in professional tinting associations

Cheap tint jobs often use inferior materials that fade, bubble, or peel. These installations may not meet legal standards. Spending more upfront saves money on removal, reinstallation, and potential fines.

Checking Your Current Tint

If you bought a used car with existing tint, verify it meets legal requirements. Many vehicles have illegal tint from previous owners.

Steps to Check:

Visit a professional tint shop for measurement
Ask your mechanic during routine service
Purchase a VLT meter (available online for $30-$100)
Have it checked during vehicle inspection

Don’t assume your tint is legal just because you haven’t been stopped. Proactive checking prevents future problems.

Window Tint Benefits Within Legal Limits

Even at legal percentages, window tint provides valuable benefits.

Advantages Include:

Reduced heat inside your vehicle (up to 60% heat rejection)
Protection from harmful UV rays (99% UV blocking)
Less glare while driving
Increased privacy
Protection for interior materials from sun damage
Potential safety benefit if glass breaks (film holds pieces together)

Legal tint strikes a balance between these benefits and safety requirements.
