Chicago toll payment basics

Chicago's toll roads — the Illinois Tollway system — require payment either at toll plazas or through an electronic account. You can pay with cash at some locations, but most drivers use I-PASS, the state's electronic toll collection system, which charges your account automatically as you drive through toll points. I-PASS works on all Illinois Tollway roads and also on toll roads in Indiana, Ohio, and other states that accept it.

If you do not have I-PASS and drive through a toll plaza without paying, the Illinois Tollway will send you a bill based on your license plate. This is called a toll violation notice, and it costs more than the toll itself — typically double or triple the toll amount, depending on how long you wait to pay.

The Illinois Tollway operates the toll roads, not the city of Chicago, so you deal directly with them for account setup, payment, and disputes. You can set up an account online, by phone, or in person at a toll plaza customer service center.

Key Takeaways

  • I-PASS is the electronic toll payment system used on all Illinois Tollway roads and accepted in multiple states; you can set up an account online at illinoistollway.com or by calling 1-800-UC-IPASS.
  • Cash payment is available at some toll plazas, but driving through without paying results in a violation notice that costs significantly more than the toll.
  • You can link I-PASS to a credit card, debit card, or bank account for automatic replenishment when your balance runs low.
  • If you receive a toll violation notice, you can dispute it online or by mail within 30 days if you believe it was issued in error.
  • I-PASS transponders are mailed to you after account setup and must be mounted on your windshield to work at toll points.

Setting up an I-PASS account

To open an I-PASS account, visit illinoistollway.com, call 1-800-UC-IPASS (1-800-824-4727), or visit a customer service center at a toll plaza. You will need your vehicle's license plate number, a valid driver's license or ID, and a payment method (credit card, debit card, or bank account information).

When you create an account online, you choose a starting balance — typically $25 to $100 — and the system mails you a transponder (the small device that communicates with toll readers). The transponder usually arrives within 7 to 10 business days. Until it arrives, you can still use your account; tolls will be charged to your license plate, and you will not receive violation notices.

Once the transponder arrives, mount it on your windshield as instructed. The device must be clean and positioned correctly for toll readers to detect it. If your transponder stops working or is damaged, you can request a replacement through your account or by calling customer service.

Payment methods and automatic replenishment

I-PASS accounts are prepaid — you load money into your account, and tolls are deducted each time you pass through a toll point. You can pay your initial balance and any future payments using a credit card, debit card, or direct bank transfer.

Most drivers set up automatic replenishment, which adds money to the account when the balance drops below a threshold you choose (for example, $10). This prevents your account from running empty and triggering violation notices. You can turn automatic replenishment on or off anytime through your online account or by calling customer service.

If you prefer not to use automatic replenishment, you can manually add funds to your account through the website or by phone. Check your balance regularly to avoid running out of money during a toll transaction.

Cash payment at toll plazas

Some Illinois Tollway toll plazas still have cash lanes, though the number has decreased over time. Cash payment is available at certain locations during specific hours, but not all plazas accept cash at all times. Before relying on cash payment, check the Illinois Tollway website or call customer service to confirm which plazas near your route accept it.

Cash tolls cost the same as I-PASS tolls for most roads, though some express lanes have different pricing. If you use a cash lane, pay the attendant or use the automated payment machine at the booth. Keep your receipt in case you need to dispute a charge.

Toll violation notices and disputes

If you drive through a toll point without paying and do not have an active I-PASS account, the Illinois Tollway will send you a toll violation notice to the address on your vehicle registration. The notice includes the toll amount plus a violation fee, which typically doubles or triples the cost of the original toll.

You have 30 days from the notice date to pay or dispute it. To dispute a notice, visit the Illinois Tollway website, call customer service, or mail a written response to the address on the notice. Common reasons for disputes include: you paid the toll but the system did not register it, the toll amount is incorrect, or the vehicle listed is not yours.

If you dispute the notice and the Illinois Tollway determines the charge was issued in error, they will cancel it. If you do not respond within 30 days, the violation becomes a debt that can affect your vehicle registration renewal and may be referred to a collection agency.

I-PASS discounts and account management

I-PASS users receive a discount on most Illinois Tollway tolls compared to cash payment. The discount varies by road and toll point but is typically 10 to 30 percent lower than the cash rate. The discount is applied automatically when your transponder is detected.

You can manage your account online anytime: check your balance, view transaction history, update your payment method, change your automatic replenishment settings, or add additional vehicles. If you have multiple vehicles, you can link them all to one account or create separate accounts for each vehicle.

If you move out of Illinois or no longer need I-PASS, you can close your account online or by phone. Any remaining balance will be refunded to your original payment method within 30 days.

I-PASS acceptance outside Illinois

I-PASS is accepted on toll roads in Indiana, Ohio, and several other states through reciprocal agreements. Your transponder will work at these locations without any additional setup. However, toll rates and discount structures vary by state and road, so you may pay a different amount than you would on Illinois roads.

If you travel frequently on out-of-state toll roads, check the Illinois Tollway website for a list of accepted systems and any special rates or requirements. Some states offer their own electronic toll systems that may provide better rates for frequent users in that state.
