I will be renting a car in Portland, and eventually driving through New Hampshire and Massachussetts to Boston's Logan airport - a one-way rental. Can I use my own Maine Ez-Pass transponder on the rental car (and disable the rental car's transponder so that it doesn't register when going through a toll station)? Since I already have one, I am not happy about the prospect of renting the use of a second one for $10-$15 per day from the rental car company. (Since I will be approaching Logan from the south through a tunnel, I know that a transponder is mandatory.) I could not find any information on this on the Maine Ez-Pass website.
