When approaching a narrow passage, depending on the side from which we approach, we may encounter one of two signs shown below. The first, which is the one in the question, indicates that oncoming traffic has priority and prohibits us from entering the narrow passage until it is possible to pass through it without forcing vehicles travelling in the opposite direction to stop. The second, for its part, would indicate that we have right of way over vehicles travelling in the opposite direction.
