Missed an Illinois Toll? Pay by Plate & 14-Day Grace Period

Missed an Illinois toll and now you’re wondering about the pay-by-plate system and that 14-day grace period? You’re not alone. The Illinois pay-by-plate system and 14 day grace period for missed tolls lets you pay after the fact, but only if you act fast.

As of 2026, the Illinois Tollway gives you exactly two weeks to settle the bill before late fees kick in. Here’s how it works and what you need to do next.

The invoice is mailed to the vehicle owner. Paying on time avoids penalties.

How the Illinois Pay-by-Plate System Works

The Illinois Tollway uses cameras to capture your license plate if you don’t have an I-Pass transponder. The system then generates an invoice and mails it to the registered owner of the vehicle. This is called pay-by-plate tolling, and it’s designed for drivers who don’t use the toll roads often.

You don’t need to stop at a toll booth. The cameras read your plate as you drive through at highway speeds. The toll amount is based on your vehicle’s class, which is determined by the number of axles and height.

Most passenger cars fall into Class 2, while larger vehicles like RVs or trucks are Class 3 or higher.

This system is part of Illinois’ open road tolling, which keeps traffic moving. It’s different from traditional toll booths where you’d pay with cash or a transponder on the spot. With pay-by-plate, you’re billed later, which is convenient but easy to forget.

The 14-Day Grace Period Explained

The 14-day grace period starts the day you pass through the toll plaza. During this time, you can pay the toll online, by phone, or by mail without incurring any extra fees. The Illinois Tollway sends an invoice to the address on file with your vehicle’s registration, so make sure it’s up to date.

If you don’t pay within 14 days, a $2 administrative fee is added to your bill. After 30 days, additional late fees apply, and the toll violation may be sent to a collections agency. This can also affect your vehicle’s registration if left unpaid.

The grace period is your window to avoid penalties. It’s not a free pass, but it does give you time to sort out the payment. If you’re renting a car, the rental company will typically handle the toll, but they may charge you an extra fee for the convenience.

How to Pay a Missed Toll Before the Deadline

Step 1: Find Your Toll Invoice

Check your mail for the invoice from the Illinois Tollway. It will include details like the date, time, and location of the toll, as well as the amount due. If you don’t receive an invoice within a week, you can look up the toll online using your license plate number and the date of travel.

Step 2: Pay Online, by Phone, or by Mail

The easiest way to pay is online through the Illinois Tollway’s website. You’ll need your invoice number or license plate information. You can also pay by phone or by mailing a check or money order to the address on the invoice.

Step 3: Confirm Payment

After paying, save your confirmation number. It may take a few business days for the payment to process. If you don’t receive a confirmation email or receipt, contact the Illinois Tollway customer service to verify your payment went through.

What If You Don’t Pay Within 14 Days?

Late Fees and Penalties

If you miss the 14-day window, a $2 administrative fee is added to your toll. After 30 days, the fee increases, and the toll violation may be reported to a collections agency. This can impact your credit score and may lead to a hold on your vehicle’s registration.

How to Dispute an Incorrect Charge

If you believe the toll charge is incorrect, you can dispute it online or by contacting the Illinois Tollway. You’ll need to provide evidence, such as proof that your vehicle wasn’t on the road that day or that you had a valid I-Pass at the time. Disputes must be filed within 30 days of the invoice date.

Pay-by-Plate vs. I-Pass: Which Should You Use?

Pay-by-plate is best for occasional drivers who don’t want a transponder. You pay after the fact, but you risk forgetting and incurring fees.

I-Pass is better for frequent toll road users. It’s a prepaid transponder that deducts tolls automatically as you drive through. You’ll save money on tolls and avoid the hassle of invoices.

Here’s a quick comparison:

Common Mistakes (And How to Avoid Them)

Forgetting to update your vehicle’s registration address is a big one. If the invoice goes to the wrong place, you might miss the 14-day window.

Another mistake is ignoring the invoice. Even if you think the charge is wrong, you still need to dispute it within the timeframe. Otherwise, you’ll face late fees.

Rental car users often assume the company handles everything. Check your rental agreement. Some companies charge extra fees for toll processing.

Who Gets Charged? (Rental Cars, Out-of-State Drivers, etc.)

The registered owner of the vehicle is responsible for the toll. For personal cars, that’s you. For rentals, it’s usually the rental company, but they’ll pass the cost to you.

Out-of-state drivers are treated the same as Illinois residents. The invoice goes to the address on file with your vehicle’s registration.

Commercial vehicles are also subject to pay-by-plate tolls. The rates are higher, and the grace period rules still apply.

Where to Check Your Toll History and Payments

The Illinois Tollway website lets you look up tolls by license plate. You can see your recent toll history and pay any outstanding invoices.

You can also call customer service for assistance. Have your license plate number and the date of travel ready.

If you have an I-Pass account, you can log in to view your toll transactions. This is the easiest way to keep track of your payments.
