Paying Illinois tolls is straightforward once you know the available options and requirements. The primary systems are I-PASS, Toll By Plate, and several online and mobile alternatives. I-PASS is the state’s electronic toll collection program, offering discounted rates and express lanes. Toll By Plate uses license plate imaging and bills the registered owner by mail. For visitors or occasional users, one-time payments and third-party apps provide flexibility. This guide explains each method, where and how to pay, account management, and how to avoid violations or missed deadlines.
I-PASS: Illinois Electronic Toll Collection
I-PASS is Illinois’ prepaid electronic toll collection system, managed by the Illinois State Toll Highway Authority (ISTHA). It uses a transponder mounted on the windshield to automatically deduct tolls as you travel. It is accepted on all Illinois toll roads, bridges, and selected neighboring facilities. I-PASS typically offers lower per-mile rates than Toll By Plate and access to dedicated express lanes. You can open an I-PASS account online, by phone, or in person at customer service centers and participating retail locations. The account requires a valid payment method for automatic replenishment to prevent service interruptions.
Setting Up an I-PASS Account
To set up I-PASS, you need a vehicle and a valid payment method. You can apply online through the ISTHA website, by phone, or at retail partners such as select AAA offices and Walgreens. You will provide vehicle details and choose account preferences, including automatic replenishment thresholds. Once activated, the transponder is mailed to you or available for pickup at select locations. Install the transponder according to instructions and register it to your account for best results. Proper registration helps ensure accurate billing and easier dispute resolution if needed.
I-PASS Discounts and Pricing
I-PASS users generally pay lower per-mile rates than Toll By Plate users. Discounts vary by facility but commonly range from about 30% to 50% off the cash or Toll By Plate rate. Monthly statements detail tolls, discounts applied, and any adjustments. If you frequently use Illinois toll roads, I-PASS often results in significant savings over time. Replenishment settings help avoid interruptions; you can set low-balance alerts and automatic top-ups to maintain active status.
Toll By Plate: Pay-by-Mail Option
Toll By Plate is Illinois’ license plate imaging system for drivers without an I-PASS transponder. Cameras capture your license plate as you pass through toll plazas or gantries. You receive a bill by mail, typically within 30 days of travel, and must pay by the due date to avoid fees. This option is convenient for occasional users or visitors but costs more than I-PASS. It’s important to ensure your address and vehicle information are current to receive bills and notices promptly.
How Toll By Plate Billing Works
After a tolling event, an image of your license plate is captured and matched to vehicle registration information. ISTHA generates an invoice sent by mail, detailing the date, location, amount due, and payment deadline. You can pay online, by phone, by mail, or at retail locations. Late payments may incur penalties, so it’s best to pay as soon as possible. If you believe the image was misread or the bill is incorrect, you can dispute it through the official process within the stated timeframe.

Common Issues and How to Resolve Them

For Toll By Plate discrepancies, compare your records with the invoice and contact ISTHA if the amounts don’t match. Respond to notices promptly to avoid additional fees or escalated collection actions.
Steps to Dispute a Toll Bill

- Contact ISTHA customer service within the stated timeframe
- Follow up in writing if needed and keep copies of all correspondence
Tips to Avoid Missed Payments and Violations

For Toll By Plate, watch mail deadlines and pay as soon as you receive the bill. Maintain current contact details with ISTHA so notices reach you promptly. If you travel often in Illinois, consider standardizing on I-PASS for cost savings and convenience. Regular account reviews help catch errors early and keep your standing in good standing.
