We've rented cars several times in France and Spain but seem to run afoul of the toll gates when trying to pay at the end of an autoroute stint.
I've searched google till blue in the face but have been unable to find a clear, simple description of what toll lanes require passes, which require credit cards, and which take cash. I know there are signs over each lane but, to me, they seem designed by pyramid builders in ancient Egypt.
Simply put, I need to know how to pick a cash lane when getting ready to pay. Seems there are multiple, ambiguous choices and panic sets in a bit when traffic behind is heavy.
I know the sign showing a human with several coins is our friend. After that I am lost - especially when the aforementioned sign is absent. Anybody?
