Which traffic sign refers to the permissible total mass?

The signs depicted refer to weight limits for vehicles on the road.

Sign 1 indicates a maximum permissible weight of 5.5 tons. This means vehicles exceeding this weight are not allowed to use that specific section of the road.

Sign 2 shows a maximum permissible total mass of 7.5 tons, specifically marked with a truck symbol, identifying it as a restriction for commercial vehicles.

Understanding these signs is crucial for compliance with German traffic laws, as exceeding the prescribed weight limits can lead to safety hazards and legal penalties. It's important to pay attention to these limitations, especially for drivers of heavy vehicles, to ensure proper road usage and safety for all.
