I-Pass

Likewise, entering or exiting the tollway system with an I-Pass allows continuous movement through the toll gate, albeit at a decelerated speed of 15 miles per hour (24 km/h).

If the account holder fails to contact the tollway authority by the due date on their violation notice, additional fines will be levied, eventually leading to having their vehicles plates, drivers license, or both, suspended.

Fines have reportedly often escalated into thousands of dollars due to the failure of the account holder to act by contacting ISTHA about the violation.

About 70% of all electronic transactions on the Indiana Toll Road are done with I-Pass transponders, according to Tollway Authority figures.

To address this imbalance, ISTHA began charging I-Pass users a three-cent surcharge on each of their Indiana tolls, effective January 1, 2010.

In September 2019, NPR radio station WBEZ revealed that the Illinois Tollway had been divulging I-Pass records to lawyers and law enforcement.

The Illinois chapter of the ACLU responded negatively to this use of I-Pass data, referring to it as "mission creep".

An I-Pass sticker transponder, introduced in 2024, which is permanently affixed to the vehicle's windshield (the perforations in the sticker will disable the transponder if removed), and does not require replacement for battery expiration.
