The Illinois E-ZPass Discount gives passenger vehicle drivers a 50% cut on tolls across the Illinois Tollway system. The discount applies automatically when you drive through a toll plaza with a working I-PASS or E-ZPass transponder mounted in your vehicle. No forms to fill. No special requests. The system reads your transponder and charges half the cash toll rate to your prepaid account.
I-PASS is the Illinois brand of the E-ZPass network. The Illinois Tollway Authority runs the program. The discount covers every toll road in the system, including I-90 (Jane Addams Memorial Tollway), I-88 (Reagan Memorial Tollway), I-294 (Tri-State Tollway), and I-355 (Veterans Memorial Tollway). The Chicago Skyway and the Indiana Toll Road also accept I-PASS for reduced rates.
How the Illinois E-ZPass Discount Works
The Illinois Tollway uses open road tolling. Overhead gantries read your transponder as you drive at full speed. The system charges your I-PASS account at the discounted rate within seconds. Cash lanes still exist at some plazas for drivers without a transponder, but those lanes charge double the I-PASS rate.
Here is what happens at a toll point:
- Transponder detected: The 50% discount applies right away. Your account is charged the lower rate.
- No transponder: A camera snaps a photo of your license plate. You pay the full cash rate through the Illinois Tollway’s Pay By Plate service, plus a $3 invoice fee per trip.
- Account balance low: The system still gives you the discount. Your saved credit card or bank account tops off the balance automatically if you set up auto-replenish.
The discount works day and night, weekdays and weekends. There is no off-peak requirement for the standard 50% savings. Every trip on a toll road with a working transponder gets the reduced rate.
Who Qualifies for the Illinois E-ZPass Discount
Any driver with a passenger vehicle can get the Illinois E-ZPass Discount. You do not need to live in Illinois. Drivers from other states with an E-ZPass, E-PASS, SunPass, FasTrak, or any other interoperable transponder get the same 50% savings in Illinois. The E-ZPass Group operates in 19 states, and all of those transponders work on Illinois toll roads.
Eligible vehicle types include:
- Cars and sedans
- SUVs and crossovers
- Pickup trucks under 7,001 pounds gross vehicle weight
- Motorcycles
- Minivans
Vehicles that do not qualify for the standard discount include commercial trucks, large RVs, buses, and vehicles pulling trailers with extra axles. Those vehicles need a commercial I-PASS account with different rates based on weight and number of axles.
What You Need to Set Up Your I-PASS Account
You need three things to start saving: a transponder, a registered account, and a payment method. The Illinois Tollway makes the process simple through getipass.com.
Step 1: Get a transponder. You can order a free I-PASS sticker transponder online or pick one up at a customer service center. The sticker version mounts to your windshield and works the same as the older hard-case model. Mount it behind the rearview mirror on the inside of the windshield.
Step 2: Open an account. You need your name, address, driver’s license number, and license plate number for each vehicle. The minimum opening balance is $20. That balance covers tolls and keeps your account active.
Step 3: Link a payment method. Add a credit card, debit card, or bank account for auto-replenishment. When your balance drops below $10, the system adds $20 automatically. You can change the threshold and refill amount anytime through your online account.
Step 4: Mount the transponder. Place it in your vehicle and wait 24 hours for activation before driving through toll plazas. Driving through a toll before activation results in a Pay By Plate charge at the full cash rate.

I-PASS Assist: Extra Savings for Low-Income Drivers

First responders employed full-time by an Illinois police, fire, or EMS agency qualify for a free transponder and account fee waiver.
Applications for these programs require proof of eligibility, such as a military discharge document (DD-214), state-issued senior ID, or agency employment verification. Processing takes 7 to 10 business days.

Frequently Asked Questions About the Illinois E-ZPass Discount
The following questions cover the most common concerns drivers have about the Illinois E-ZPass Discount program. Each answer includes specific details about eligibility, costs, and account management based on current Illinois Tollway policies.
1. Can out-of-state drivers get the Illinois E-ZPass Discount?
Yes. Any driver with a working E-ZPass, I-PASS, or other interoperable transponder receives the 50% discount at Illinois toll plazas. The system does not check your state of residence. Your home state’s E-ZPass account gets charged the reduced Illinois rate automatically. Drivers from Florida, New York, Ohio, and other E-ZPass states get the same savings as Illinois residents without opening a separate account.
2. How much does an I-PASS transponder cost?
The I-PASS sticker transponder costs $0 with a new account. You only pay the $20 minimum opening balance, which goes toward your toll charges. Hard-case transponders cost $9.95 plus shipping. There are no monthly account fees for personal accounts. Commercial accounts pay a $10 monthly fee per account regardless of the number of transponders linked to it.
3. What happens if I drive through a toll without my transponder?
A camera photographs your license plate. The system matches Virginia Customer Service Services the plate to your I-PASS account if registered. You get charged the full cash rate plus a $3 invoice fee per missed toll. The transponder must be physically mounted and active in the vehicle at the time of the toll for the discount to apply. Driving through a toll with a dead transponder battery triggers the same penalty.
4. Does the I-PASS discount work on the Chicago Skyway?
Yes. The Chicago Skyway accepts I-PASS and E-ZPass at a reduced rate compared to cash or credit card payment. The current I-PASS rate on the Chicago Skyway is $3.30, compared to $6.60 for cash payment. Drivers without a transponder can use the Pay By Plate option, but it costs more than the I-PASS rate and includes processing fees.
5. Can I share my I-PASS transponder between two vehicles?
No. Each transponder must be linked to a specific license plate in your account. Moving a transponder between vehicles causes the system to flag the transaction. Use one transponder per vehicle for accurate billing. The Illinois Tollway allows up to four transponders per personal account at no extra cost beyond the initial deposit.
6. How do I replace a lost or stolen I-PASS transponder?
Log in to your account at getipass.com and deactivate the missing transponder immediately. Then order a replacement through the website or by calling customer service. A new sticker transponder costs $0 and ships within 5 business days. You maintain your account balance and do not lose the $20 opening deposit when you replace a transponder.
7. Are there discounts for riding in carpools or HOV lanes?
Illinois Tollway roads do not have traditional HOV lanes with carpool discounts. The I-PASS Flex transponder, which switches between standard and HOV modes, works in other states like Virginia, but Illinois uses open road tolling without HOV restrictions. Carpooling still saves money because you split the toll cost with passengers, even though the toll itself stays the same per vehicle.
