As we approach 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 we have priority over vehicles travelling in the opposite direction.
The second one, on the other hand, would indicate 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.
