What do these traffic signs indicate?

The traffic sign depicted indicates the start of a no-overtaking zone, which lasts for 200 meters. In Germany, this means that drivers are not allowed to overtake other vehicles within the specified distance ahead.

This rule is in place to ensure safety in areas where visibility is limited, such as curves or intersections, where overtaking could result in dangerous situations. The sign specifically signals drivers that they must remain aware of their surroundings and cannot pass other vehicles until they are beyond the designated area. Understanding such signs is crucial for safe driving and compliance with traffic regulations.
