What Is the Illinois I-PASS Assist Program?
This is a financial assistance program run by the Illinois Tollway to make toll roads more affordable. It’s part of the existing I-PASS electronic tolling system, which lets drivers pay tolls without stopping at booths. The Assist program specifically targets low-income motorists who rely on toll roads for work or daily travel.
The discount applies automatically once you’re approved and using an I-PASS transponder. There’s no separate device or account, just the same I-PASS tag with a reduced rate.
Who Qualifies for the 50% Toll Discount?
Eligibility hinges on three main factors: residency, income, and vehicle type. You must be an Illinois resident with a valid driver’s license and vehicle registration. Your household income must be at or below 200% of the federal poverty level, which varies by household size.
Only passenger vehicles qualify, no commercial trucks, trailers, or motorcycles. The vehicle must be registered in your name or a household member’s name.

How the I-PASS Assist Discount Works

The 50% reduction is applied at the time of the transaction, so you’ll see the lower rate on your statement.
The discount only works with an active I-PASS account. If you don’t have one, you’ll need to open an account and request a transponder as part of the Assist application. The transponder itself is free for Assist participants.

Costs, Fees, and What You Actually Pay

How to Use Your I-PASS Assist Transponder
