Core: Unequal-rank junction: B6, B7 and the priority road

An unequal-rank junction always has a sign regulating priority (Book p.107-108) — that is exactly what distinguishes it from the equal-rank junction of the previous atom. Sign B6 obliges you to give way to drivers on the crossing road, but does not prescribe a full stop: if the road is clear, you may continue at reduced speed. Sign B7 does require a full stop, even if the road looks empty. Sign B1 marks the start of a priority road: all traffic from side roads must give way to you until sign B2 marks the end of that priority road — B2 is therefore just as important as B1. One final variant: at a junction of an unpaved road with a paved road, the driver on the unpaved road gives way to the driver on the paved road, even if the latter is a horse rider.
