About Unequal-rank junction: B6, B7 and the priority road: which statement is WRONG?

Sign B1 applies 'until sign B2 indicates the end of the priority road'.
✓ Sign B6 means you are required to come to a full stop before the junction.
At a junction of an unpaved road with a paved road, the driver on the unpaved road gives way to the one on the paved road, even if that is a horse rider.
At a junction of an unpaved and a paved road, the driver on the unpaved road gives way to the road user on the paved road, even if that is a horse rider.

Correct answer: Sign B6 means you are required to come to a full stop before the junction.

Explanation

'If you are required to stop, the sign is not B6 but B7.' B6 = give way to crossing traffic without a mandatory full stop; only B7 forces a stop

Sign B1 applies 'until sign B2 indicates the end of the priority road'. Priority on a priority road is therefore a bounded stretch between B1 and B2, not a permanent status
