REMEMBER, when using the Illinois I-Pass, and pulling a trailer, there are 3 different pay scales in use, depending upon the time of day, or night. Late at night, I think after 11 PM to around 6 AM is the cheapest rate. Your car or truck rate is not effected by these times, unless towing. If your truck is a duley, you are required to pay as a 3 axle vehicle. I know people who have that extra rear wheel, and use there I-Pass, without a problem, but if you hit the cash box, one with an attendant, you might see that extra fee. We have one I-Pass, and use it with our car, truck or truck and fiver. As stated, register your vehicles, and pay special attention to your plate number. They have to match exactly, Or you will be hearing from them.
