Understanding I-Pass costs helps Chicago drivers save money while traveling locally or across EZ Pass states.

• Toll rates for trucks range $3–$15 per plaza depending on axle count and route.

Violation, Late Payment & Penalty Costs
Drivers who skip tolls or use outdated transponders face violation fines. Illinois enforces strict tolling policies to encourage I-Pass usage. Avoiding fines significantly reduces overall I-Pass and EZ Pass travel expenses.
