New highway code rules are in place from today. Most of them are just formalising common sense principals that are already part of what we teach (e.g. leaving appropriate space for pedestrians,cyclists, horses etc), but the giving way to pedestrians waiting to cross a minor road you are entering/emerging from is new (and likely to cause confusion with not everyone knowing about it).

Naturally we’ll cover all of it with our pupils 🙂
