What should you anticipate in this situation?

You chose the correct answer. In this situation, you should anticipate that the driver of the red vehicle might fail to see you. This is important because intersections and curves on rural roads can limit visibility, increasing the risk that another driver—especially one on a side road or coming from a minor road—may overlook your approach. Always reduce your speed and remain alert so you can react if another vehicle unexpectedly enters your path. Anticipating the mistakes of other drivers is a key principle of safe driving in Germany.
