Our Verdict

E-ZPass wins for operations covering multiple eastern states. Its 19-state network provides the broadest coverage and most consistent toll payment experience for fleet operations.

I-PASS wins specifically for any truck that runs Illinois regularly. The 50% Illinois Tollway discount is too significant to ignore — hundreds or thousands of dollars per year for frequent Illinois operators.

If you run Illinois weekly: get I-PASS. For general eastern US operations: E-ZPass from your base state is the practical choice. Either works on the shared network.

Frequently Asked Questions

Yes, E-ZPass is accepted on Illinois tollways. However, E-ZPass accounts from other states do NOT receive the I-PASS 50% toll discount on Illinois tollways. You pay the full cash rate with out-of-state E-ZPass.

You can have accounts with both, but you should only have one transponder active in the vehicle at a time to avoid double billing. Most drivers choose one transponder that covers their most frequent toll routes.

The toll interoperability landscape is improving but still fragmented. E-ZPass has the broadest reach. SunPass (Florida) and PikePass (Oklahoma) have limited interoperability. For nationwide trucking, Bestpass consolidates all toll systems into one account.
