I originally drove on the highway in southern France. Each section had a different toll. Some had toll booths where you had to take a card, while others required you to pay first without a card. Look at the signs above the toll booths to see if you need to take the ETC lane or the regular lane with the toll sign. There was a toll to get to Paris, and there was a toll on one section of the highway to Monaco. There were no tolls on the highways in southern France, but I remember there was an automatic machine at Nice airport that could exchange paper money for coins. I think the toll machines automatically counted the coins you put in, so you didn't have to count them yourself. There were a lot of one-way streets in France, especially in small towns, and the roads were very narrow. Also, always lock your car doors when you leave it, because we were waiting at a red light on a road in Gannat and someone opened our trunk. Fortunately, we had read in the guidebook to lock the car doors before getting out, so we didn't get stolen. This time, we picked up the car in Paris and drove to the Loire Valley ?
