What must you do when you see this traffic sign?

This sign is a mandatory instruction sign in Germany that tells you to pass a traffic island or an obstacle on the right-hand side. The blue circle with a white arrow pointing downwards to the right means you must keep right. It is important because it guides safe traffic flow around physical obstacles or separation islands, preventing confusion or accidents.

You are not required to turn right at this sign—only to pass on the right side of the obstruction indicated. This helps maintain orderly and predictable movement on the road. Remember, following these signs is mandatory; ignoring them can be dangerous and is against traffic rules.
