What applies here?

In the scenario depicted, the police officer is directing traffic at a crossroads. According to German traffic rules, if a police officer is present and signaling, their instructions must be followed before proceeding. This means that while the crossroads may be crossed, it might not be safe to do so without further signals from the officer.

The correct combination of answers would emphasize that while crossing is permitted, waiting for the officer's signals is crucial for safety and legal compliance. This highlights the importance of adhering to a police officer's commands, as they are authorized to manage traffic situations that may not be clear to drivers. Always prioritize their instructions in such situations to ensure the safety of all road users.
