How does I-Pass work?

I-Pass is an innovative electronic toll collection system designed to streamline the process of paying tolls in Illinois. When a vehicle equipped with an I-Pass transponder enters a toll plaza, special equipment installed overhead reads the transponder's information, such as account details and balance. The toll amount is then deducted from the driver's prepaid account, eliminating the need to stop and manually pay. I-Pass users enjoy benefits such as reduced toll rates, faster travel times, and the convenience of not needing exact change or tickets. The system automatically replenishes the prepaid account when the balance runs low, ensuring uninterrupted use. I-Pass can be used on all the Illinois Tollway roads and even on some tolled bridges. Overall, I-Pass provides a convenient and efficient way for drivers to pay tolls in Illinois.
