Window Tint Laws in Illinois, Missouri and Iowa: What to Know Before You Tint
By Pristine Window Tint · Published · Updated
Short answer
Illinois, Missouri and Iowa each regulate how dark vehicle window tint can be, especially on windshields and front side windows. Limits differ by state and vehicle type, and laws change. Confirm current rules for your vehicle and the state where it's registered before tinting; medical exemptions may apply in some cases.

How tint laws are measured
Tint laws usually refer to VLT — visible light transmission — the percentage of visible light that passes through the glass and film combined. A lower percentage means a darker window. Laws often also address reflectivity and windshield strips.
What's typically regulated
- Windshields — usually limited to a strip at the top, or restricted to specific films.
- Front side windows — commonly the most tightly regulated.
- Rear side and back windows — rules can differ by vehicle type, such as sedans vs. SUVs and trucks.
- Reflective or mirrored films — often restricted.
Where you live matters
Quincy sits at the meeting point of three states. Your vehicle is generally subject to the laws of the state where it's registered, but you're also driving through neighboring states. If you commute across state lines, factor that into your shade choice.
Medical exemptions
Some states allow darker tint for certain medical conditions with documentation. Requirements vary — check with your state's licensing or transportation agency.
