Which action is an appropriate response to a yellow curb?

When you see a yellow curb, it indicates a loading zone where stopping is allowed but parking is restricted to brief activities. The primary purpose of a yellow curb is to facilitate the quick drop-off and pick-up of passengers or cargo, allowing for smooth traffic flow and accessibility in busy areas. Stopping is acceptable, but only for the purpose of letting someone in or out of the vehicle or to load or unload items, and the vehicle must not be left unattended.

Options that suggest parking your vehicle unattended or using the curb for long-term parking contradict the regulations associated with yellow curbs, which are not designed for those purposes. Similarly, waiting for an extended period, such as two hours, is inappropriate since the intent is to promote short-term stopping rather than prolonged use of that space. Thus, stopping only to drop off passengers or cargo is the correct and appropriate response to a yellow curb.
