Missed a Toll in Illinois? You Have 14 Days

Every toll road in Illinois is cashless. There are no coin baskets, no cash lanes, and nothing to stop for. You pass under a gantry at highway speed and it either reads your transponder or photographs your license plate.

If you drove through without an I-PASS or E-ZPass, you are not in trouble yet. You have 14 days from your date of travel to pay through the Illinois Tollway's Pay By Plate service with no fees and no fines.

Miss that window and the cost of one missed toll starts climbing well beyond the toll itself.

What Happens If You Wait

The Illinois Tollway escalates on a published schedule, and it does not stop.

Timeline	What happens
First 14 days	Pay through Pay By Plate with no fees or fines
Day 30	First invoice mailed, adds $3 per toll for passenger vehicles
Day 60 and 90	Additional invoices, fees continue to grow
Day 120	Notice of Violation issued, adds a $20 fine per toll
Day 150	Final Order of Liability, all tolls, fees, and fines owed
Day 180	Sent to collections, possible registration hold and litigation

A single toll that would have cost under a dollar can end up over $70 by the time it reaches violation status. Ignore it further and it can affect your ability to renew your vehicle registration.

The Tollway is explicit about the scale of this. Since cashless tolling began in 2020, more than six million invoices have gone unpaid, representing over $110 million in unpaid tolls.

Pay By Plate Is the Thing to Know About

Most new drivers have never heard of it, and it is the mechanism that keeps a missed toll from becoming a fine.

Pay By Plate lets you enter your license plate and payment information without owning a transponder. You can set it up before you travel, or after, as long as you are inside the 14-day window.

One practical tip from the Tollway itself: if you have already traveled, backdate your plate information to your first date of travel so the system captures the tolls you already accrued.

Two things worth knowing. Pay By Plate charges the cash rate, which is roughly double the transponder rate, so it is a safety net rather than a strategy. And it works only on the Illinois Tollway, not on toll roads in other states.

I-PASS Is Cheaper, and There Is an Assistance Program

If you drive the Tollway with any regularity, a transponder is the cheaper route. Transponder users pay roughly $0.30 to $1.50 per plaza for passenger vehicles, while drivers without one pay about double.

The Tollway also runs I-PASS Assist, which offers income-eligible customers lower prepayment requirements, waived transponder deposits, and dismissal of invoice fees when an account is activated. For a young driver on a tight budget, that is worth looking into rather than absorbing cash-rate tolls indefinitely.

Why This Catches New Drivers Specifically

There is nothing on the road to tell you that you owe money. You do not slow down, you do not see a booth, and no light flashes.

If you are driving a car registered to a parent, the invoice goes to the registered owner, not to you. Families discover a stack of unpaid tolls weeks later, often after the free window has already closed.

If you are borrowing a car or driving one registered to someone else, tell them you used the Tollway. That conversation costs nothing. The alternative costs $3 per toll and rises from there.

Frequently Asked Questions

What is Pay By Plate?

An Illinois Tollway service that lets you pay tolls using your license plate and a payment method, without a transponder. It can be set up before or after travel.

The Bottom Line

Cashless tolling means nothing on the road tells you that you owe money.
