How are vehicles with a permissible total mass up to 2.8 t allowed to be parked here?

The parking sign indicates that parking is allowed for vehicles with a permissible total mass of up to 2.8 tons. According to German traffic regulations, when parking in such areas:

1. **Vehicles like the car illustrated** can park parallel to the curb.
2. **Caravans** that meet the weight requirement can also park in the designated area, as they are included under the same mass limitation.

The option regarding small cars parking diagonally to the driving direction isn't applicable here because only parallel parking is typically allowed unless otherwise indicated. It's essential to choose all relevant options to comply with the traffic rules fully.
