What must you be prepared for?

In this situation, you should be prepared for all three hazards: pedestrians crossing the street, possible visual obstructions from parked cars, and vehicle doors opening. The street is lined with parked vehicles, making it harder to see people who might step out between them. Pedestrians, especially children or elderly people, can appear suddenly. Parked cars can also obstruct your view, and someone might open a door unexpectedly into traffic. It’s important to drive carefully and at a reduced speed to react in time to any of these dangers. Your answer is correct because you recognized all the potential risks.
