What should you anticipate?

You are correct to anticipate all three situations:

1. Pedestrians might suddenly step onto the road from between parked cars or the sidewalk, as visibility is limited, and they may not use a designated crossing.
2. Vehicle doors might be opened unexpectedly by passengers in parked cars, posing a hazard for passing vehicles and cyclists.
3. Vehicles parked along the street or waiting may begin moving without much warning, especially in busy urban areas.

In German traffic rules, when you see parked cars, pedestrians close to the road, and cyclists, you must be especially cautious and reduce speed. This allows you time to react and avoid accidents caused by sudden pedestrian movements, opening doors, or vehicles starting to move. Always be vigilant in such complex traffic environments to ensure safety for everyone.
