Which of the following signs obliges to give way to vehicles entering or approaching a narrow section of the road in the opposite direction?

Erklärung

The red-bordered white circle with a large black arrow pointing down and a smaller red arrow pointing up gives priority to oncoming traffic at a narrow section, so the approaching driver must yield. The empty inverted triangle is a general give-way sign for a junction, while the red-bordered warning triangles do not impose this narrow-passage duty.
