During my recent trip to the Sunshine State from the Winter Wonderland, I crossed the Ohio River using the I65 toll bridge between IN and KY. The signs said that the bridge would read my plate and bill me. When I started crossing, I received a Poliscan Alert first from the front, then from my rear sensors. I have a 2-CPU set-up, 3 sensors front, 3 sensors mounted rear. Has anyone else come across this? I shut off at 3 seconds but if I had let it go JTG, would I avoid getting the bill?
