If you look in the Tom Tom menu, there's a setting that labels French cameras as "Agincourt", "Waterloo", etc. A small white flag symbol shows where they are.
If they do stop you, take a close look at the charge sheet. You may find the items "Mother was a hamster" or "Father smelt of elderberries". These are not legitimate offences.
Never been stopped in the ten years we travel through France. Just try avoid towns as crit air may be an issue if you havent one !!!. Tbh we havent ever had beam bender, GB or UK or whatever stickers.....
