What must you be aware of here?

You answered everything correctly. In this residential area, you must be especially aware of three things. First, vehicles may exceed the speed limit even where it's not allowed, so always watch for speeding cars. Second, junctions with limited visibility can be hard to notice, which increases the risk of not seeing crossing traffic or pedestrians. Third, children may suddenly run onto the road from between parked cars or houses. Being alert to all these dangers is essential for safe driving in residential areas. This awareness helps you react in time and avoid accidents.
