What iPass Pay by Plate Is and How It Works
iPass Pay by Plate is an electronic toll payment system used on toll roads in Illinois. Instead of stopping at a toll booth to pay with cash or a card, this system automatically captures images of your vehicle's license plate and bills you later. The system operates on major tollways including the Illinois Tollway system, which manages over 286 miles of toll roads across the Chicago metropolitan area and beyond.

When you drive through a toll plaza equipped with Pay by Plate technology, overhead cameras photograph your license plate. The system then matches that plate number to vehicle registration information and sends an invoice to the registered vehicle owner's address. This means you don't need to have a transponder device in your car or maintain a pre-loaded account. The transaction happens automatically based on your license plate information alone.
The Illinois Tollway implemented this system to make toll payment more convenient for occasional users and those who don't want to maintain a transponder account. According to the Illinois Tollway, Pay by Plate transactions account for a significant portion of daily toll collections. The system processes hundreds of thousands of transactions daily across the state's toll network.
The technology behind Pay by Plate uses optical character recognition (OCR) software to read license plates with high accuracy. Multiple cameras capture images from different angles to ensure the plate is correctly identified. If there's any issue with plate recognition—such as an obscured or damaged plate—the system has procedures to handle these situations.
Practical Takeaway: Pay by Plate works through automatic license plate recognition, meaning you can use toll roads without stopping or having special equipment, and you'll receive an invoice by mail for payment.
Understanding Toll Invoice and Payment Process
After driving through a toll plaza, the registered owner of the vehicle receives a toll invoice in the mail. This invoice typically arrives within 10 to 30 days of the toll transaction. The invoice clearly shows the date of travel, the specific toll plaza location, and the toll amount charged. Most toll invoices include information about where and how to pay, including payment methods and any applicable deadlines.

Toll payment can be made through several methods. The most common options include online payment through the tollway's website, payment by phone using a credit or debit card, payment by mail by sending a check, or automatic payment if you set up an account. The Illinois Tollway website provides a dedicated payment portal where drivers can enter their invoice number and license plate information to locate and pay outstanding tolls.
The payment amount shown on a Pay by Plate invoice reflects the actual toll rate for that specific plaza and time of travel. Unlike transponder accounts that may offer discounted rates, Pay by Plate typically charges the standard toll rate. For example, on the Illinois Tollway system, toll rates vary based on the number of axles on your vehicle and the distance traveled. A standard passenger vehicle might pay anywhere from $0.70 to $5.50 or more per toll plaza, depending on the specific location and toll zone.
Late payment policies are an important consideration. If payment isn't made within a certain timeframe—usually 30 to 60 days from the invoice date—additional late fees may be added to your bill. These fees can range from $5 to $25 per unpaid toll, depending on the tollway authority's policies. Repeated non-payment can result in vehicle registration holds, collection actions, or boot placement on the vehicle in some jurisdictions.
Practical Takeaway: You'll receive a mailed invoice after using a Pay by Plate toll road, and you should pay within the stated timeframe using online, phone, mail, or automatic payment methods to avoid late fees.
Setting Up Online Account Management for Pay by Plate
Many drivers find that setting up an online account with the tollway authority makes managing Pay by Plate charges simpler. The Illinois Tollway offers an online portal where you can search for outstanding tolls by entering your license plate number. This allows you to view all unpaid tolls associated with your vehicle and pay multiple tolls at once rather than waiting for individual invoices.

Creating an account typically requires you to provide basic information including your vehicle's license plate number, vehicle registration information, and contact details. The account can store multiple vehicles if you own more than one and use different vehicles on toll roads. Once the account is established, you can log in at any time to check for outstanding tolls and transaction history.
The online portal also allows you to set up automatic payments for future tolls. With this feature, when a toll is recorded, payment is automatically charged to your stored payment method—either a credit card or bank account—rather than waiting for a paper invoice. This reduces the number of bills you receive by mail and can help ensure you never accidentally miss a payment deadline. Automatic payment enrollment typically requires authorization and confirmation before it becomes active.
Account features usually include a transaction history that shows the dates, times, locations, and amounts of all toll transactions. This information can be useful for expense tracking or if you need to dispute a charge. Some systems also allow you to set up email or text notifications when a toll is recorded or when a payment is due, helping you stay informed about your toll usage.
Practical Takeaway: Setting up an online account lets you track tolls, view payment options, and potentially set up automatic payment to manage invoices more efficiently.
Common Questions About Toll Rates and Charges
One frequently asked question concerns variation in toll rates. Toll amounts aren't uniform across all plazas or times of day on many toll road systems. On the Illinois Tollway, rates can differ based on several factors: the vehicle's axle count (passenger vehicles are charged differently than trucks), the distance traveled between plazas, and sometimes the time of day. Dynamic pricing, where rates fluctuate based on traffic conditions, has been tested or implemented on some toll roads, though traditional flat-rate systems remain most common.

Another question involves what happens if your license plate isn't clearly visible or is damaged. If the Pay by Plate system cannot read your plate, the toll booth operator or a human reviewer typically examines the image and attempts to manually identify the vehicle. If identification isn't possible, the toll may be flagged for investigation. In some cases, drivers receive a separate notice requesting plate information rather than an automatic invoice. If you've had recent accidents or obtained a new vehicle with a different plate, updating your registration helps ensure the system matches you correctly.
Questions also arise about tolls charged to vehicles you don't own or when a vehicle is sold. If you receive a toll invoice for a vehicle you no longer own, you should contact the tollway authority with proof of sale. Similarly, if you purchase a vehicle and it comes with outstanding tolls, you may be able to provide evidence of the sale date to shift liability to the previous owner. The process varies by state and tollway operator, so contacting the authority handling the tolls is necessary to resolve ownership disputes.
Some drivers wonder about out-of-state vehicles and reciprocal agreements. Most major toll systems have reciprocal agreements allowing them to bill vehicles registered in other states. For example, an Ohio resident driving through Illinois tolls will receive an invoice through the same system as a resident. The Illinois Tollway has agreements with neighboring states to process and collect tolls from out-of-state vehicles through their registered owner information.
Practical Takeaway: Toll rates vary based on vehicle type and distance, issues with unreadable plates are usually resolved through human review, and toll authorities can track vehicles across state lines through reciprocal agreements.
What Happens If You Don't Pay a Pay by Plate Toll
Non-payment of tolls can result in escalating consequences. The timeline typically begins when an invoice is mailed to the registered vehicle owner. If no payment is made by the deadline shown on the invoice—usually 30 to 60 days—a late notice may be sent with additional fees added. A single unpaid toll might incur a late fee of $5 to $25. If multiple tolls remain unpaid, these fees accumulate quickly.

After additional missed payment notices, the tollway authority may escalate collection efforts. This can include referring the debt to a collection agency, which may contact you by phone or mail. Collection agencies have varying approaches, but they generally attempt to secure payment through persistent contact. A notation about the unpaid toll debt may be reported to credit bureaus, potentially affecting your credit score or your ability to obtain loans or credit cards.
Some states and tollway authorities hold vehicle registrations if tolls remain unp
