What must you be prepared for?

Your answer is completely correct because in a situation like this, you must always be prepared for:

1. Persons crossing: Pedestrians might suddenly step onto the street from between parked cars or from behind obstacles, so you need to be attentive.

2. Visual obstructions: The parked cars on both sides create blind spots, limiting your view of what might be coming onto or across the road.

3. Vehicle doors opening: Drivers or passengers of parked cars may open doors suddenly, which could obstruct your path or cause accidents.

In German traffic rules, when driving past parked vehicles, you must reduce speed and be cautious to anticipate these hazards. This helps prevent accidents with pedestrians and avoids collisions caused by suddenly opened doors or vehicles pulling out unexpectedly.
