Learn About Illinois Toll Pay By Plate System

What Is Illinois Pay By Plate?

Illinois Pay By Plate is a toll payment system used on the Illinois Tollway system. Instead of stopping at a toll booth to hand over cash or a transponder, the system reads your vehicle's license plate as you pass through a toll location. The Illinois Tollway then sends you an invoice based on the miles you traveled.

The system operates on major highways in Illinois, including Interstate 90, Interstate 94, Interstate 88, and Illinois Route 390. These roads form a network of toll roads spanning over 280 miles across northeastern Illinois. The system processes millions of transactions each year.

Pay By Plate works through automated cameras positioned at toll plazas. As your vehicle passes through, high-speed cameras capture an image of your rear license plate. The Tollway's computer system matches the plate to a vehicle and calculates the toll amount based on your entry and exit points. You do not need to stop or slow down significantly.

This payment method differs from traditional toll collection where drivers stopped at booths. It also differs from I-PASS, which is Illinois Tollway's electronic transponder system. With I-PASS, drivers purchase a small electronic device that mounts on their windshield and communicates with toll readers. Pay By Plate requires no device—just your license plate.

The system launched to handle traffic flow more smoothly and reduce congestion. According to the Illinois Tollway Authority, the Pay By Plate system processes toll transactions for thousands of daily commuters and occasional users. Understanding how it works helps you know what to expect when driving on Illinois toll roads.

Practical takeaway: Pay By Plate is an automatic toll collection method that reads your license plate and sends you an invoice later. You do not need special equipment or to stop at toll booths.

How Your Toll Invoice Is Calculated and Sent

When you travel through an Illinois toll road using Pay By Plate, the system calculates your toll based on distance traveled. The Tollway divides the highway system into zones. Your toll amount depends on which zone you enter and which zone you exit. The farther you travel, the more you pay.

For example, a trip from one zone to an adjacent zone costs less than a trip spanning five zones. The Illinois Tollway publishes a toll schedule showing rates for different entry and exit point combinations. As of recent years, Pay By Plate rates for standard passenger vehicles range from approximately $1.50 to $4.50 for common trips, though rates can vary.

After passing through the toll location, the Illinois Tollway processes the license plate image within a few days. The system attempts to match the plate number to a registered vehicle owner. Once matched, a toll invoice is generated and mailed to the registered address of the vehicle.

The invoice includes details such as the date of travel, the toll location, the amount due, and a due date for payment. Most invoices must be paid within a specific timeframe, often 14 to 21 days. The invoice will provide clear instructions on payment methods, which typically include online payment, mail payment by check, and telephone payment.

If the license plate cannot be read clearly or is not registered in the Illinois Secretary of State's database, the system may send a notice asking for vehicle information. This can happen if the plate is obscured, damaged, or the vehicle is newly registered out of state.

Practical takeaway: The Illinois Tollway uses license plate images to calculate your toll based on distance traveled and mails you an invoice within days. Payment is typically due within two to three weeks.

Online payment through the official Illinois Tollway website is one of the most common methods. You can visit the website, enter your invoice number and license plate information, and pay using a credit card, debit card, or electronic bank transfer. Online payment is available 24 hours per day, 7 days per week. This method is immediate—your payment is processed right away, and you receive a confirmation number.

Mail payment is another option. You can write a check and mail it to the address shown on your invoice. Include your invoice number with the payment. Mail payment typically takes longer to process, sometimes one to two weeks, so mail payments should be sent early to meet the due date.

Phone payment allows you to call a customer service number provided on your invoice and pay over the telephone using a credit or debit card. A representative can answer questions about your invoice while processing your payment.

Some invoices may also offer the option to set up automatic recurring payments if you regularly travel the toll roads. This can reduce paperwork and the chance of late payments.

The cost of payment depends on the method chosen. Online and phone payments using a credit card may include a small processing fee. Direct bank transfers may not include a fee. Check payments through the mail typically have no processing fee.

It is important to pay by the due date shown on your invoice. Late payments may result in additional penalties and fees. If you cannot pay by the due date, you should contact the Illinois Tollway customer service to explore payment plan options.

Practical takeaway: You can pay your toll invoice online, by mail, or by phone. Pay by the due date to avoid late fees and penalties.

What Happens If You Do Not Pay Your Toll Invoice

Not paying a toll invoice on time can result in additional costs and complications. The Illinois Tollway has specific procedures for handling unpaid tolls.

If your invoice is not paid by the due date, the Tollway typically sends a second notice. This notice may include a late fee added to your original toll amount. Late fees can range from $5 to $25 per transaction, depending on how long the toll remains unpaid. The total amount owed increases significantly if you ignore multiple invoices.

If the toll and late fees remain unpaid for several months, the account may be referred to a collection agency. A collection agency will attempt to contact you by phone and mail to demand payment. A collection account on your record can impact your ability to borrow money or obtain credit in the future.

In some cases, the Illinois Tollway may suspend your vehicle registration or prevent you from renewing it. The Tollway can report unpaid tolls to the Illinois Secretary of State's office, which may block vehicle registration renewal until the debt is resolved. This means you would not be able to legally drive your vehicle.

If you moved and did not receive your invoice, you should contact the Illinois Tollway as soon as possible to provide your current address. If the invoice contains errors or you dispute the charges, you can request a review. Contact customer service to explain the situation and ask for an investigation.

The Illinois Tollway may also offer payment plans for those who cannot pay the full amount immediately. If you are facing financial hardship, contacting customer service early is important. Waiting until collection efforts begin makes negotiation more difficult.

Practical takeaway: Unpaid tolls result in late fees, collection action, and possible vehicle registration suspension. Pay invoices on time or contact the Tollway if you cannot pay.

Differences Between Pay By Plate and I-PASS

Pay By Plate requires no equipment or registration. If you drive on toll roads occasionally, the system automatically captures your license plate and sends you an invoice. This makes Pay By Plate convenient for infrequent users who do not want to purchase a device. However, Pay By Plate offers no discount on toll rates.

I-PASS is an electronic transponder system. You purchase a small device that mounts on your windshield. As you approach a toll location, the device communicates with toll readers, and your toll is deducted from your prepaid account. I-PASS requires you to purchase the device initially and add money to your account before traveling. However, I-PASS offers significant discounts compared to Pay By Plate. As of recent years, I-PASS users may pay 25% to 50% less per toll transaction than Pay By Plate users.
