Illinois tolls are collected on specific highways and bridges, and you can pay them in several ways depending on which road you're using and whether you have an I-PASS account.

Illinois operates toll roads through the Illinois Tollway system, which includes Interstate 90 (the Jane Addams Memorial Tollway), Interstate 94, Interstate 88 (the Ronald Reagan Memorial Tollway), and Illinois Route 390. If you drive these routes regularly or occasionally, you need to understand how payment works and what happens if you don't pay.

The main payment methods are I-PASS (a prepaid electronic account), Tollway.com (one-time payment by license plate), or cash at toll plazas where they still exist. Each method has different costs and requirements. Choosing the right one depends on how often you use the tolls and whether you want to set up an account.

Key Takeaways

  • I-PASS is an electronic transponder that gives you a discount on every toll and is the cheapest way to pay if you use Illinois tolls regularly.
  • You can pay tolls without an account by using Tollway.com within seven days of driving, or by mail if you receive a bill.
  • If you don't pay within the required timeframe, the Illinois Tollway sends violation notices and can add late fees and penalties to your bill.
  • Cash payment is no longer available at most toll plazas, so you must have I-PASS or pay online to avoid a violation notice.
  • Rental cars, commercial vehicles, and motorcycles have different payment rules and may require separate accounts or arrangements.

How I-PASS Works and What It Costs

I-PASS is a prepaid account linked to an electronic transponder (a small device you mount on your windshield). When you drive through a toll plaza, the transponder communicates with the toll reader and deducts the toll from your account balance. I-PASS users pay a lower toll rate than drivers who pay by other methods — typically 30 to 50 percent less per toll, depending on the road and vehicle type.

To open an I-PASS account, you go to ipass.illinois.gov, provide your vehicle information and payment method (credit card, debit card, or bank account), and order a transponder. The transponder is mailed to you, usually within five to seven business days. You can add money to your account online anytime, and the system automatically replenishes your balance when it drops below a set amount if you choose that option.

I-PASS accounts are tied to a specific vehicle license plate. If you drive multiple vehicles on Illinois tolls, you need a separate transponder and account for each one. If you sell your vehicle or change plates, you must update your account information or close the account to avoid bills being sent to the wrong person.

Paying Without an I-PASS Account

If you don't have I-PASS, you can pay tolls through Tollway.com using your license plate number. After you drive through a toll plaza, you have seven days to log into Tollway.com, enter your plate number, and pay the toll amount plus a processing fee. The processing fee is higher than the I-PASS rate but lower than violation penalties, so paying on time is important.

If you don't pay within seven days, the Illinois Tollway sends a violation notice to the vehicle owner's address (based on your registration). The notice includes the original toll amount, a violation fee (typically $20 to $50 per violation), and instructions for payment by mail or online. If you ignore the violation notice, additional penalties and collection efforts can follow.

Some rental car companies include toll payment in their rental agreement or charge you directly if tolls are incurred. Check your rental agreement before driving on Illinois tolls to understand whether you or the rental company is responsible for payment.

What Happens If You Don't Pay a Toll

The Illinois Tollway system is automated, so unpaid tolls are tracked by license plate. If you don't pay within seven days of driving, a violation notice is mailed to the registered vehicle owner. This notice is not a traffic ticket — it's a civil violation — but ignoring it creates serious problems.

If you don't respond to the violation notice within the stated important date (usually 30 days), the Tollway can refer your account to a collection agency, report the debt to credit bureaus, or place a hold on your vehicle registration renewal. Some states also allow the Tollway to report unpaid tolls to the Secretary of State, which can prevent you from renewing your driver's license or vehicle registration in Illinois or other states that participate in reciprocal enforcement.

If you receive a violation notice and believe it's incorrect — for example, you paid online but the system didn't process it, or you weren't driving the vehicle — you can dispute it by responding to the notice with documentation. Keep receipts from any online payments you make through Tollway.com.

I-PASS for Commercial Vehicles and Motorcycles

Commercial vehicles (trucks, buses, and vehicles over a certain weight) have separate I-PASS accounts and toll rates. The toll amount depends on the vehicle's axle count and weight. If you operate a commercial vehicle on Illinois tolls, you need a commercial I-PASS account, which you can open at ipass.illinois.gov under the commercial vehicle section.

Motorcycles can use I-PASS, but the transponder mounting is different because of the vehicle's shape. I-PASS provides specific instructions for motorcycle mounting. Motorcycles pay the same rate as passenger vehicles with I-PASS.

If you drive a commercial vehicle without the correct I-PASS account, you'll be charged the higher non-I-PASS rate and may receive violation notices if you don't pay. Using a passenger vehicle I-PASS on a commercial vehicle, or vice versa, can also trigger violations.

Disputing a Toll Violation or Incorrect Charge

If you receive a violation notice and believe the charge is wrong, respond in writing to the address on the notice within the important date provided. Include copies of any documentation — a receipt from an online payment, proof you sold the vehicle, or evidence you weren't driving at the time. The Tollway reviews disputes and may dismiss the violation if you provide sufficient proof.

If your I-PASS account shows a charge you didn't authorize or a duplicate charge, contact I-PASS customer service through ipass.illinois.gov or by phone. They can review your account history and issue a refund if an error occurred. Keep records of all your toll transactions and account statements.

If you've already paid a violation and later discover it was processed in error, you can request a refund. The process varies depending on how you paid, but the Tollway generally processes refund requests within 30 to 60 days.

Connecting Toll Payment to Vehicle Registration

Illinois does not automatically prevent vehicle registration renewal if you have unpaid tolls, but the Tollway can place a hold on your registration if your account is referred to a collection agency or if the debt is significant. This hold is separate from your registration renewal process — it's an enforcement action by the Tollway.

If you're renewing your registration and discover a hold, you'll need to resolve the toll debt before the hold is lifted. You can pay the outstanding tolls and violation fees directly through Tollway.com or by mail. Once payment is processed, contact the Tollway to confirm the hold is removed before attempting to renew.

If you're buying a used vehicle in Illinois, check whether the previous owner left unpaid tolls on the plate. The new owner becomes responsible for those tolls once the registration is transferred. You can contact the Tollway before completing the purchase to verify the toll history on the plate.

Frequently Asked Questions

Can I use my I-PASS from another state on Illinois tolls?

No. I-PASS is specific to Illinois and works only on Illinois Tollway roads. If you have a transponder from another state (such as E-ZPass from the Northeast), it will not work on Illinois tolls. You must open a separate Illinois I-PASS account. Some states have reciprocal agreements, but Illinois does not currently participate in those programs for toll payment.

What if I lose my I-PASS transponder?

Contact I-PASS customer service through ipass.illinois.gov to report the lost transponder. They will deactivate it and mail you a replacement. You'll be charged a replacement fee (typically $10 to $25). Until the new transponder arrives, you can pay tolls using Tollway.com with your license plate number.

Do I need to pay tolls if I'm just passing through Illinois?

Yes. If you drive on any Illinois Tollway road, you must pay the toll. There is no exemption for out-of-state drivers or vehicles passing through. You can pay through Tollway.com within seven days of driving, or you can open an I-PASS account if you use the tolls frequently.

Can I get a refund if I overpaid my I-PASS account?

Yes. If your I-PASS account balance is positive and you no longer need the account, you can request a refund through ipass.illinois.gov or by contacting customer service. Refunds are typically processed within 30 to 60 days and are sent to the original payment method on file.

What happens if I move out of Illinois but still have an active I-PASS account?

You should close your I-PASS account to avoid future charges and to receive a refund of any remaining balance. If you keep the account open and continue to drive on Illinois tolls, charges will continue to be processed. Contact I-PASS customer service to close your account and request a refund of any remaining balance.
