How E-Pass Works and What Happens When You Don't Pay
What E-Pass Is and How the Payment System Works
E-Pass is an electronic toll collection system used on toll roads in Illinois and Indiana. Instead of stopping at a booth to pay cash, a small transponder mounted on your windshield communicates with readers as you drive through a toll plaza. The toll amount is deducted from a prepaid account you set up with the Illinois Tollway or Indiana Toll Road, depending on which system you use.
The payment happens automatically. When your transponder passes under a reader, the system identifies your account and charges the toll immediately. Your balance decreases in real time. You can check your account balance and transaction history online or through a mobile app, and you can add money to your account whenever you want—there is no minimum balance requirement.
E-Pass accounts are tied to a specific vehicle and license plate. If you drive a different car, you will need a separate transponder for that vehicle, or you can request a temporary transponder if you are borrowing a car occasionally. The account itself belongs to you, not to the vehicle, so you can transfer it to a new car if you sell your current one.
Key Takeaways
- E-Pass charges tolls automatically by reading a transponder on your windshield, and the cost comes out of a prepaid account you control.
- You must maintain a positive balance in your account; if your balance drops to zero, tolls will not be charged and you may receive a violation notice instead.
- If you do not pay a toll—whether because your account was empty or your transponder malfunctioned—the toll authority will send you an invoice by mail, usually within 30 days.
- Unpaid tolls accrue late fees and can result in vehicle registration holds, license suspension, or civil judgment if the debt goes unpaid for months.
- You can set up automatic replenishment so your account refills when the balance drops below a threshold you choose, reducing the risk of running empty.
Setting Up Your Account and Adding Money
To open an E-Pass account, you go to the Illinois Tollway website (illinoistollway.com) or the Indiana Toll Road website (indianatollroad.com), depending on which system you will use. You provide your name, address, vehicle information (make, model, license plate), and a payment method—either a credit card, debit card, or bank account for ACH transfers.
Once your account is created, the tollway mails you a transponder. Installation takes about two minutes: you clean a small area on the inside of your windshield and stick the transponder there. The system is ready to use as soon as the transponder is mounted, even if you have not yet added money to your account (though you will incur violations if you drive through tolls with a zero balance).
You can add money to your account online, by phone, or through the mobile app. Most people set up automatic replenishment, which means the account refills itself when your balance drops below a level you choose—for example, $10 or $25. This prevents the account from going empty and triggering violation notices. Replenishment happens instantly when the threshold is crossed.
What Happens If Your Account Balance Runs Out
If you drive through a toll plaza and your account balance is zero or negative, the toll is not charged to your account. Instead, the system records the vehicle and license plate, and the toll authority treats it as an unpaid toll. You will receive a violation notice in the mail, usually within 30 days of the incident.
The violation notice includes the toll amount plus a penalty fee. The penalty varies by state and by how many unpaid tolls you have accumulated, but it is typically $25 to $50 per violation on top of the actual toll. The notice will tell you how much you owe in total and provide instructions for payment.
If you pay the violation notice within the timeframe stated (usually 30 days), the matter is closed. If you do not pay, the toll authority can escalate the debt by placing a hold on your vehicle registration renewal, suspending your driver's license, or referring the debt to a collection agency. Some states also allow the toll authority to file a civil judgment against you, which can affect your credit and lead to wage garnishment.
How Late Payments and Violations Affect Your Driving Privileges
Unpaid toll violations do not immediately suspend your license or prevent you from renewing your registration. However, if the debt remains unpaid for several months—the exact timeline varies by state—the toll authority can report the debt to the state's Secretary of State or Department of Motor Vehicles. At that point, your registration renewal will be blocked until you pay the outstanding balance.
A registration hold means you cannot legally renew your vehicle registration. If your registration expires and you have not paid the toll debt, you are driving with an expired registration, which is a separate violation and can result in a traffic stop and additional fines.
In some cases, particularly if the debt is large or has been unpaid for a year or more, the toll authority may request a driver's license suspension. This is less common than a registration hold, but it is possible. The best way to avoid these consequences is to pay violation notices promptly or to set up automatic replenishment so your account never runs empty in the first place.
Disputing a Toll Charge or Violation Notice
If you believe a toll charge or violation is incorrect—for example, your transponder malfunctioned, you were not actually in the vehicle, or the amount charged is wrong—you can dispute it. Contact the toll authority's customer service line and explain the issue. Have your account number and the date of the disputed toll ready.
The toll authority will investigate. If your transponder was defective, they may waive the violation fee (though you will still owe the actual toll). If you can show that you were not the driver, you may be able to provide the name of the person who was driving, though this does not always remove your liability as the vehicle owner.
If the toll authority denies your dispute, you can request a formal hearing or appeal. The process and timeline vary by state, so check the toll authority's website for the specific steps in your jurisdiction. Keep copies of all correspondence and documentation in case you need to escalate the dispute.
Transferring Your Account or Closing It
If you sell your vehicle or no longer need E-Pass, you can close your account online. Any remaining balance in your account will be refunded to the payment method you used to fund it, usually within 5 to 10 business days. You should also remove the transponder from your windshield and return it to the toll authority if they request it, though some systems allow you to keep it.
If you buy a new vehicle and want to keep your E-Pass account, you can update your vehicle information online. You will receive a new transponder for the new vehicle, and your account balance carries over. This is simpler than closing one account and opening another.
If you move to a different state or region, check whether E-Pass is accepted there. E-Pass works on Illinois and Indiana toll roads, but if you relocate to a state with a different toll system, you will need to open a separate account with that system. Some toll systems are interoperable, meaning a transponder from one system works on another, but this is not universal.
Frequently Asked Questions
Can I use E-Pass on toll roads outside Illinois and Indiana?
E-Pass is specific to Illinois Tollway and Indiana Toll Road systems. Other states have their own toll collection systems—for example, Florida uses SunPass, and Ohio uses E-ZPass. If you travel to a state with a different system, you will need a transponder for that system or you can pay tolls with cash or a credit card at some plazas.
What if I lose my transponder or it stops working?
Contact the toll authority's customer service and request a replacement. They will mail you a new transponder at no charge. In the meantime, if you drive through a toll plaza without a working transponder, the toll will be recorded as unpaid and you will receive a violation notice. Once you receive the replacement and mount it, future tolls will be charged normally.
Can someone else use my E-Pass account?
Your E-Pass account is tied to your vehicle's license plate, not to a specific driver. Anyone can drive your vehicle and the tolls will be charged to your account. If you lend your car to someone frequently, make sure your account has sufficient balance so tolls do not go unpaid.
How long does it take to receive a violation notice after I miss a toll?
Violation notices are typically mailed within 30 days of the unpaid toll. The exact timeline depends on how quickly the toll authority processes the transaction and generates the notice. Check your mail regularly and pay the notice promptly to avoid late fees and registration holds.
Will unpaid tolls show up on my credit report?
Unpaid tolls do not automatically appear on your credit report unless the toll authority refers the debt to a collection agency or files a civil judgment against you. If that happens, the debt can affect your credit score. Paying the violation notice before it escalates to that stage keeps it off your credit record.
