Understanding Illinois Tint Laws
Window tint laws in Illinois regulate how dark your vehicle windows can be tinted. The rules are measured in VLT (Visible Light Transmission) — the percentage of light that passes through the glass and film combined.
Getting pulled over for illegal tint in Illinois can result in a fix-it ticket or fine. Before tinting your vehicle, always confirm current regulations with your local DMV as laws can change.
A reputable tinting shop will know local IL tint laws and ensure your installation stays within legal limits.
