No, 35% window tint is illegal in Illinois for passenger vehicles. State law mandates front-side windows allow ≥35% light transmission, but rear windows may not exceed 35% if factory-tinted. Non-compliance risks citations under 625 ILCS 46/5-302, enforced by local law enforcement and the Illinois State Police. A 2026 amendment tightens rear-window exemptions for medical waivers, requiring physician certification for tints below 30%.
