Most road signs are universal all round the world and they are recognisably described in the hand outs. Mind you I don't think it changes the way anybody drives. What is more dangerous a young bloke doing 80 in a 60 zone, or an oldie doing 40 on the same road at the same time that you are doing your 60?

My point is that the handouts you talk about help to associate their language with that of yours. By the way did you know there was a, (I think you call them Referendums), held when your nation was born as to what your language was to be, German or English?
