Stickers on the back
National stickers like the B etc are not required here. There is no need. The only foreign plates they ever see are Canadian and I guess Mexican.
Re the insurance. Just be prepared to be stopped by a police man who is wetting himself over a registration tag he had never seen. If the insurance card does not say Allstate, State Farm or something he recognizes be prepared for a long wait while Bubba checks it out. Waving around some international carnet or some card in , god help you French, is not going to go down very well.
