What do the white markings on the road mean in this situation?

The white triangular markings on the road indicate a duty to give way, usually related to the right-before-left rule. In German traffic law, these markings are placed before an intersection where you must yield to vehicles coming from the right unless otherwise indicated. This rule ensures a safe and orderly flow of traffic at intersections without traffic lights or signs. You must slow down, look carefully, and let other vehicles with the right of way pass before proceeding. This marking does not indicate a traffic-calming zone or warn about road surface conditions. Understanding this will help you recognize when you need to yield at intersections in Germany.
