The sign "Clear the shoulder" is used to indicate that drivers should remove their vehicles from the shoulder of the road. This typically applies in situations where parking on the shoulder is not allowed or when it is necessary to keep the shoulder clear for emergency vehicles or road maintenance.

In Germany, the shoulder of the road is often reserved for emergencies, breakdowns, or other specific purposes. When you see this sign, it is important to follow the instruction and ensure that your vehicle does not obstruct the shoulder area, allowing for safe passage for other road users and emergency services.
