The PA Turpike Commission will catch it on camera and send a nasty gram. I have an EZPass, one of the early ones. They had intermittent & premature battery failure. I read about it in the paper, and sure 'nough, a few months later mine randomly failed. I got a $40 nasty gram threat from the idiots. The stupid thing is that they KNEW they were having problems, they even noted that they had an EXIT transaction, but no ENTRANCE transaction, and they treated me like a felon!!!!!! MORONS!!!!!!
