While I think of it, a couple more tips for driving in France........Speed traps all over, fixed and movable. Stop signs - STOP for at least 3 seconds, even if the road is clear both ways. Not a stop 'n' go like UK - usually a fed in watching distance, behind a bush..........Finally RED Triangle with an 'X' on a white back ground means the traffic from the right has Right of Way - ie, bumbling along at 50kph in a village and old geezer in his 'sans permis' can and do come out from a side road onto the main road - allways be aware of this rule! The Feds will pick on Foreiners as they are easy pickings - ie confiscate car if not paying fine - they will take you to a cash point!
Happy holidays
