Free Guide to Illinois Toll Pay By Plate

What Is Illinois Toll Pay By Plate?

Illinois Toll Pay By Plate is a system that allows drivers to pay tolls on Illinois roads without stopping at a toll booth or having a transponder device in their vehicle. Instead of using cash or a physical toll tag, the system reads your vehicle's license plate as you drive through a toll plaza. The toll authority then sends you a bill in the mail based on the photo and registration information associated with your plate.

The system operates on major toll roads in Illinois, including the Chicago Skyway, the Illinois Tollway system, and other designated toll facilities. According to the Illinois Tollway, millions of vehicles use the Pay By Plate system annually. The technology uses high-speed cameras positioned at toll plazas to capture images of license plates. Within days, the toll authority matches the plate number to vehicle registration records and generates an invoice.

Pay By Plate differs from other payment methods available on Illinois toll roads. Some drivers use I-PASS, a prepaid transponder account that offers discounted toll rates. Others use credit or debit cards at specific toll plazas. Pay By Plate serves drivers who do not have a transponder and do not want to stop at a toll booth. It is particularly useful for occasional users, out-of-state visitors, and rental car drivers.

The system has been in place in Illinois for several years and continues to expand. The Illinois Tollway reports that Pay By Plate accounts for a significant percentage of toll transactions on their roadways. Understanding how this system works helps drivers know what to expect when using toll roads in Illinois and how they will be billed.

Practical Takeaway: Pay By Plate is a no-stop toll payment method that photographs your license plate and sends you a bill later. It works on most Illinois toll roads and does not require advance registration or special equipment in your vehicle.

How the Pay By Plate System Works

The Pay By Plate process is straightforward and happens automatically as you drive. When you pass through a toll plaza on an Illinois toll road, overhead cameras capture a clear image of your vehicle's license plate. These cameras are equipped with high-speed photo technology designed to work in various weather and lighting conditions, including nighttime driving and heavy rain.

After the photo is taken, the Illinois Tollway or Chicago Skyway (depending on which toll facility you used) processes the image. Their staff or automated systems read the license plate number and cross-reference it with Illinois Secretary of State vehicle registration records. This process typically takes several days to a week. The toll authority then matches the plate to the vehicle owner's information and determines the appropriate toll amount.

Once the toll authority has identified the vehicle owner, they mail an invoice to the registered address on file with the Illinois Secretary of State. The invoice shows the date you used the toll road, the specific toll plaza or road segment, and the amount owed. Most invoices include a payment due date, usually 30 days from the mailing date. You can pay by mail using the invoice, or many toll authorities offer online payment options through their websites.

The technology behind Pay By Plate has improved significantly over the years. Modern cameras use optical character recognition (OCR) technology to read plates accurately, even when they are dirty or partially obscured. The system is designed to correctly identify plates in the vast majority of cases. However, occasional errors do occur, particularly with similar-looking plate numbers or when plates are difficult to read.

Pay By Plate tolls are generally higher than the discounted rates offered to I-PASS holders. For example, a toll that costs $1.50 with I-PASS might cost $2.00 or more when paid by plate. This price difference encourages drivers to use transponders, which move traffic faster and reduce congestion at toll plazas. The exact toll amount depends on the specific road and location where you use it.

Practical Takeaway: Your license plate is photographed at toll plazas, your vehicle is identified through registration records, and you receive a mailed invoice within one to two weeks. You then pay the invoice by mail or online, typically within 30 days.

Toll Amounts and Payment Options

Understanding the cost of using Illinois toll roads under Pay By Plate is important for budgeting and trip planning. The Illinois Tollway maintains a toll schedule that lists all rates on their system. Rates vary significantly based on your vehicle type and the distance traveled. Passenger cars typically pay different amounts than trucks or recreational vehicles, with larger vehicles paying higher tolls.

On the Chicago Skyway, tolls for passenger vehicles range from approximately $2.00 to $6.00 depending on your entry and exit points. The Illinois Tollway charges vary by segment; for example, a short segment on Interstate 90 might cost $1.50, while a longer route across the state might cost $5.00 or more. The Illinois Tollway website provides a toll calculator where you can enter your entry and exit points to see the exact charge before you drive.

Pay By Plate rates are consistently higher than I-PASS transponder rates. An I-PASS holder might pay 50 percent less for the same trip. For example, a $2.00 toll paid by plate might only cost $1.00 with I-PASS. This reflects the cost savings the toll authority gains from faster processing with transponders. If you use toll roads frequently, the savings from an I-PASS could amount to hundreds of dollars per year.

When you receive your mailed invoice, you have several payment options. Most toll authorities accept payments by mail using a check or money order. You can send payment to the address listed on your invoice. Many toll authorities also offer online payment through their websites. Some accept credit cards, debit cards, or electronic bank transfers. A few toll facilities may charge a small processing fee for credit card payments, so check the invoice for details.

If you do not pay your invoice by the due date, late fees typically apply. Penalties vary but often range from $10 to $25 per unpaid toll. If tolls and late fees remain unpaid for an extended period, the toll authority may report the debt to a collection agency or suspend your vehicle registration. Some toll authorities offer payment plans for large outstanding balances.

Practical Takeaway: Pay By Plate tolls cost more than I-PASS rates but less than stopping at a toll booth in some cases. Pay invoices by mail, online, or through accepted payment methods listed on your bill. Missing payment deadlines results in significant late fees.

Managing Your Pay By Plate Account and Invoices

While Pay By Plate does not require registration or an account in the traditional sense, understanding how to manage your invoices and communication with toll authorities is important. When you drive through a toll plaza without I-PASS, you are automatically enrolled in the Pay By Plate system. There is no action needed on your part to be part of the system. However, keeping accurate contact information with the Illinois Secretary of State helps ensure you receive your invoices.

The key to managing Pay By Plate is staying organized with your invoices when they arrive. Create a system for tracking bills—whether a filing folder, a spreadsheet, or a note in your calendar. Keep invoices until you have confirmed payment, as they contain important information needed to verify transactions and resolve disputes if they occur. Some toll authorities are moving toward electronic invoicing, which reduces paper mail but requires you to monitor email for notices.

If you drive a rental vehicle or a vehicle not registered to you, the rental company or vehicle owner will receive the invoice, not you. Rental car companies typically pass these charges to the renter's credit card on file. If you are responsible for the toll charges, contact the vehicle owner or rental agency to arrange payment. Disputes over who owes the toll may require documentation, such as rental agreements or proof of vehicle use.

Some toll authorities offer online portals where you can view your account history, recent tolls, and payment status. To create an account on these portals, you typically need your vehicle's license plate number and zip code. These portals vary by toll authority—the Illinois Tollway has its own system, while the Chicago Skyway has a separate one. Checking these portals periodically helps you catch invoices early and confirms that your tolls have been processed correctly.

If you notice an error on your invoice, such as an incorrect toll amount or a toll for a trip you did not make, contact the toll authority directly. Most toll authorities have customer service phone numbers and online dispute forms. Disputes usually require submitting information about
