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 according to the German right-before-left rule. This means you must yield to traffic coming from your right at the next intersection. These markings serve as a clear visual cue for drivers to slow down and prepare to give way, ensuring safe and orderly flow of vehicles. They are not related to speed calming zones or warnings about road surface conditions. Understanding these markings helps you know when you must give priority to other vehicles, which is essential for traffic safety in Germany.
