What must you do when you see this traffic sign?

This traffic sign indicates that you must pass on the right side of an obstacle, such as a traffic island or road divider. It is a mandatory direction sign, meaning it directs the driver to follow a specific path to ensure safe and orderly traffic flow.

You are not being asked to turn right in general, nor is it a prohibition of turning left before the sign. Instead, it strictly instructs you to keep to the right side of the obstacle indicated.

Remember this sign for situations with traffic islands or roadworks: Always pass on the side the arrow points to—in this case, the right side. This ensures safety and compliance with German traffic regulations.
