What will we do at this sign?
A)Stop in any case.
B)Give way to crossing traffic.
C)We will be prohibited from passing through the narrow passage if I force vehicles travelling in the opposite direction to stop.Correct
When approaching a narrow passage, we may find, depending on the side from which we approach, one of the two signs below.
The first one, which is the one in the question, indicates that the opposite direction has priority and prohibits us from entering the narrow passage as long as it is not possible to cross it without forcing vehicles travelling in the opposite direction to stop.
The second one, on the other hand, would indicate that we have right of way over vehicles travelling in the opposite direction.
