What should you anticipate?

Your answer is fully correct. In this traffic situation, you need to anticipate three potential hazards:

1. Pedestrians may suddenly step onto the road from between parked vehicles or from the sidewalk. Visibility is limited because of the parked cars, so be ready to react quickly.

2. Doors of parked vehicles may be opened unexpectedly by people inside or outside the cars. This can cause an obstruction or even lead to collisions if you pass too closely.

3. Vehicles parked at the roadside or waiting in the queue may begin moving again. They might pull out, start moving forward, or change lanes, so be prepared to adjust your speed or position safely.

In German traffic rules, such anticipatory driving behavior is important for safety in urban areas with limited visibility and mixed road users like cyclists and pedestrians. Always reduce speed and stay vigilant in such scenarios to avoid accidents.
