What must you be prepared for in this situation?

In this situation, you need to be prepared for multiple potential hazards.

1. Oncoming traffic can appear unexpectedly, especially if visibility is blocked by the truck. This is a crucial factor to always consider when driving.

2. Truck drivers may exit their vehicles suddenly. This can happen more frequently if they are making deliveries or need to inspect something. Being aware of this increases safety for all road users.

3. Traffic signs could be hidden behind the truck, which can prevent you from seeing important information regarding speed limits or road conditions. Knowing this is vital for making informed driving decisions.

Understanding these points aligns with German traffic regulations that emphasize vigilance and awareness of surroundings to prevent accidents. Always be alert and ready to react to changing conditions on the road.
