From the 1st July a breathaliser kit has to be carried, cost 1 in Roady stores. Sat Nav is legal but must not display radar info, this may or may not be law yet, I have not seen the definitive implementation or start date.
The breathaliser kit is a typical piece of political nonsense, if you are a **** artist you are not likey to self breathalise and the cops will do it for you if you get caught. Soon there will be no room for luggage with all the junk the polito's want us to carry.
I would add that in some departments all radar warning signs have been removed and on the autoroutes they now have cameras hidden in the armco barriers.
If you go to
www.viamichelin.fr and put in a route, it will show all fixed radar points if it is still legal to show them.
