In what direction can you continue driving at the mentioned intersection, if you are driving a truck with a maximum permissible weight of 3 tons?

Explanation
The blue circle requires straight travel, and the white plate below it shows only a black goods-vehicle silhouette, limiting the command to that defined class. A 3-tonne goods vehicle is below the 3.5-tonne threshold of the symbol-only class plate, so its driver may choose any otherwise permitted direction.
