About Unequal-rank junction: B6, B7 and the priority road: which statement is correct?
A horse rider does not drive a vehicle, so from an unpaved road you only have to give way to vehicles on the paved road, not to a rider.
Sign B6 means you are required to come to a full stop before the junction.
Sign B1 applies 'until sign B2 indicates the end of the priority road'.
At a junction of an unpaved road with a paved road, the driver on the unpaved road has priority, because that road is harder to drive on.
Explanation
trap: status without an end. Book p.108 - 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
