The sign "Prohibition for vehicles carrying dangerous goods that require labeling" is a regulatory sign used in Germany to indicate that vehicles transporting dangerous goods, which must have specific labeling, are not permitted to enter or pass through the area where the sign is posted.

This prohibition is important for maintaining safety in areas where the presence of such goods could pose a risk to public safety, such as residential neighborhoods, near schools, or in crowded places. The purpose of this sign is to prevent potentially hazardous materials from being transported in places where they could cause harm due to accidents or spills.

Drivers should be aware of these signs and ensure that they do not drive their vehicles carrying dangerous goods into restricted areas. Ignoring this sign can lead to fines and further legal consequences.
