Toll roads will have a blue sign with "peage" under the area name. They usually start with a booth that dispenses a ticket. You then insert this ticket into a toll booth at the end of that toll road. You are then told how much the toll is. My advice would be to use a bumbag or tankbag to keep these tickets and money for the tolls. Keep a few 5 Euro notes and a bunch of 2 Euro coins handy.
When we bisected france, I think the cheapest toll we encountered was just over 2 Euro, and the most expensive was just over 10 Euro.
The toll roads make short work of doing distance in france so if you're pressed for time they're very handy. The minor roads are excellent quality and in general, traffic is quite sparce on the minor roads.
