What is correct in this situation?

In this scenario, the situation involves a motorbike approaching from the right, which typically means you must yield to that vehicle according to German traffic rules. The sign you see indicates that vehicles from the right have the right of way unless specified otherwise.

When navigating an intersection like this, it's crucial to always allow vehicles coming from the right the right of way, especially if they are approaching ahead of you. Your decision to yield to the motorbike is correct and shows attentive driving behavior.

In addition, if you intended to make a left turn, signaling your intention is also important, but it should not override yielding to the right of way if the motorbike is present. This highlights the need to understand the combination of rules: yielding to a vehicle with the right of way while also signaling your intentions when appropriate. Knowing these rules helps ensure safety and compliance with traffic regulations.
