Illinois Tollway____________________
If I am driving a rental car on the Illinois Tollway, how can I pay my tolls?
First, check with your rental car company on its policy for paying tolls. Some rental car companies provide transponders. In such cases, be sure you understand how to use the transponders and how you will be charged for transponder-based tolls. Inquire about transponder availability and fees with the rental agent.
Second, if your rental car company does not provide a transponder or you do not want to use the transponder they provide, you have two options:
โข Pay the cash tolls.
โข Use your I-PASS or E-ZPass transponder.
Be sure to mount the transponder on the inside of the windshield, next to the rearview mirror, to help ensure that the transponder signal is received.
Review your I-PASS account activity regularly to ensure the charges are accurate.
We do NOT recommend adding rental car license plates to your account.
In the event your transponder signal is not properly read while in the rental car, there is a possibility you will receive a violation notice. The violation notice will be sent to the rental car company, which is the registered owner of the vehicle. The rental car company then has two options: 1) by Illinois law, it may re-assign the violation notice to you based on its record of who was renting the vehicle when the violations were incurred; or 2) it may choose to pay the notice and bill you. If a rental car agency chooses to pay the notice and bill you, you will not be eligible for the settlement guidelines.
