My EZ Pass died. I blew through the Pennsylvania Turnpike from Breezewood to the Ohio border without paying. Their toll barriers don't have a gate, and they give zero feedback as to whether your transponder registers or not. No green light or “Paid” or “Go EZPass.” When I got to the Ohio Turnpike, there is a gate that goes up and down. It did not go up, so I took a ticket and while my wife was driving, I called EZ Pass Maryland. They diagnosed the problem as an expired battery in my transponder, which is 13 years old. They say the batteries only last 7-10 years. Obviously, from my experience, they can last a little longer. Anyway, EZ Pass MD mailed a replacement to my house, and it was there when I returned. I've talked to friends and relative who use EZ Pass. Nobody knew that they have batteries that will eventually expire. I didn't know.
