Core: The 30 km/h zone: where it lies, and why its end has no fixed rule

A 30 km/h zone is mainly laid out in places with a lot of mixed traffic — fast and slow mixed together — and near schools (Book p.90). That is a different reason than the woonerf: the woonerf is about pedestrians ON the roadway, the 30 km/h zone is about tempering mixed traffic. The entrance to a 30 km/h zone is often an inrit/uitrit: when entering or exiting you then give way to all road users, just like at any other inrit. But the end of the zone is not always an uitrit — the book explicitly shows a counter-example: sometimes it is simply an equal-priority junction, where the ordinary priority-from-the-right rule applies. So never automatically assume the inrit/uitrit rule at the end of a zone; look at the junction itself.
