I got an iPass a few years back due to frequent trips to Chicago and Kentucky from Minnesota. The Kennedy bridge over the Ohio River going from Indiana to Kentucky is another toll organization, but they must contract with iPass because it took the toll from my balance and I didn’t have to mail it in. A bit over $2 just to cross the river.

Can someone answer this question for me? When i got my iPass (just a couple years ago) I had to register it to the vehicle I bought it for and give license plate number. I was told by the attendant at the booth (first oasis as you enter Illinois from Wisconsin) that it would only work in that vehicle because the iPass areas also had license plate recognition cameras. I was also told by someone else (can’t remember whom) that this was not the case for older iPass transponders. Is this all true? Or can I switch my iPass between vehicles? I’ll do an internet search, but wonder if anyone here has first hand knowledge rather than just heresay?

EDIT: Search didn’t take long... https://www.illinoistollway.com/documents/20184/86147/I-PASS+FAQs_0917.pdf/bba788df-a923-4597-98d3-8621fbe2bdf8?version=1.0

Evidently, you can use it for multiple vehicles, but they (Illinois tollway) are “encouraging” you get a separate one for each vehicle. Guess the lady at the desk was just “encouraging” it a bit stronger by telling me I needed one per car. I see now on my getipass.com account where I can add vehicles.

Quick tip...for I-Pass I turned off auto replenish and use manual replenish. I am able to load $10 at a time even though it says $20 minimum. Evidently the software doesn’t enforce it.

If using manual replenish, don’t forget to stay on top of it... if you’re forgetful, keep on auto replenish.
