FastToll Illinois is an app that provides an easier way to pay for highway tolls on Illinois tollways. The app allows users to pay for their tolls through FastToll, which keeps track of each toll plaza they pass through. This is a convenient way to avoid the hassle of stopping at a toll booth, and it is especially helpful for people who do not have an active I-Pass account. It also makes it easier for people to drive through the fast lane without having to maintain an active I-Pass account.

FastToll has partnered with the Illinois Department of Transportation (IDOT) to make the app a one-stop destination for all their toll requirements. IDOT is the agency that manages the tollways in Illinois.

How does it work?

When you first open the app, it will ask you to enter the license plate number of the vehicle you are driving.
