What is the basic rule for observing hand signals given by German police officers regarding traffic parallel to their outstretched arms?

The basic rule for observing hand signals given by German police officers regarding traffic parallel to their outstretched arms is that traffic may proceed. When officers extend their arms horizontally, it signifies that vehicles and pedestrians can move through the intersection or area without stopping. This signal indicates that the situation is safe for movement, and drivers and pedestrians should take advantage of this signal to continue on their way.

In the context of traffic management, this hand signal is especially important as it provides clear direction and maintains the flow of traffic, preventing confusion and ensuring safety on the roads. Understanding these signals is key for anyone driving or navigating in areas where German police officers are directing traffic, as adherence to these signals helps in maintaining order and reducing the risk of accidents.
