What would be considered illegal parking with respect to the loading of passengers?

Parking longer than necessary for loading or unloading is considered illegal parking because it violates regulations designed to ensure the safe and efficient movement of vehicles and pedestrians. Loading zones are specifically designated to facilitate quick pick-ups and drop-offs. These areas are not intended for long-term parking, which can obstruct traffic flow and impede other vehicles and pedestrians.

By limiting the duration of parking in loading zones to only what is necessary for these activities, the law promotes public safety and accessibility. This ensures that spaces remain available for others who need to load or unload passengers, maintaining order within high-traffic areas.

In contrast, the other choices do not directly represent the legal framework surrounding loading zones. For example, simply parking in a residential area or during restricted hours might not relate directly to the act of loading or unloading passengers, making those situations less relevant to the specific context of the regulation concerning loading zones.
