Illinois Tollway is a free Android app that allows you to pay unpaid tolls, enroll, and manage your I-PASS account or Pay By Plate service directly from your smartphone. With this app, you can avoid fines and fees by adding your plate and payment information for up to 14 days after your initial travel. You can also backdate your plate information to reflect your beginning date of travel if you have already missed a toll.

If you are an I-PASS customer or looking to enroll, you can now manage your account right from the Tollway's app. You will receive account notifications and will be able to manage your entire account online. Additionally, if you are renting or borrowing a vehicle without an I-PASS or E-ZPass transponder, Pay By Plate is the perfect solution for you. Simply enter the plate, payment, and travel dates and times within 14 days of your initial travel, and you're all set.

The app is easy to use and navigate. Once you download the app, log in to manage your Pay By Plate service or enroll in I-PASS. Overall, Illinois Tollway is an excellent app for toll payment and account management, making it convenient and hassle-free for users.
