Confused on I Pass and Sun Pass etc--- toll roads ????

Also remember, if you are operating a Class C, frequently the iPass transponder will not transmit if you have it stuck in the windshield due to the design of the cabover interfering with transmission. They also make a version that attaches to your front license plate which is far more practical for the Class C's.

After a certain number of missed tolls, they will begin charging you a hefty fine each time they have to manually look up your information from the database.

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.

Here is a link to the I-Pass from Illinois. This should answer all your questions.

We have an iPass unit (Indiana) that we velcro in either our truck or car... whichever one we're using at the time. In the Indiana system, we were told that we needed to register both vehicle's in their system. Works from Illinois to the Northeast, and south through West Virginia. Not compatible with Florida's system, but I read somewhere that this may change. When towing, the toll gate automatically registers the number of axles and charges accordingly. We were on many toll roads last September between Mass and Maryland (DC area) and really appreciated not having to stop at all of the toll booths. Was never charged in error either (as far as I can tell). Wouldn't go without one.

Is the Illinois I-Pass good in any other states?

The I-pass is comatible with any of the EZ Pass systems east. I think some states like Indiana have a different name but they all work together. You head West or South (Texas, Oklahoma, Florida come to mind) and the I-pass won't work.

If you only tow a trailer you won't have a problem. I think you need to register its plate as one of the vehicles though, I'm not certain. It gets compiicated for people who tow another vehicle that sometimes they want to take through toll booths on its own, but I don'tthink this is your case. If is is an either/or situation for your tow vehicle and your SUV one transponder will work. Otherwise you might need two.

We have E-Z Pass transponders. One in the motorhome that is programmed for the motorhome and tow car. One in the car for the car alone. The one in the car is kept is a foil bag that it came in to avoid extra charge for the car when it is being towed. FYI, we got our transponders free from Mass. I don't know if they still offer them free. E-Z Pass works in whichever states participate in the program. We are very very happy with ours. We bypass long cash lines each trip.
Good luck,

We have the I-Pass and have the Velcro strips in our other cars so we can transfer the box when needed. You need to logon to their website and register your vehicles that you are using it in. You do not need anything else for your tow. The I-system senses your vehicle and anything behind it and charges appropriately. You will not get charged unless you have your trailer/tow along. It works in many other states--just read on the signs going up to the toll or go online to the I-Pass website.
