What does a yellow curb indicate?

A yellow curb indicates that you may only stop long enough to load or unload passengers or cargo. This regulation is in place to promote efficient traffic flow and ensure that these areas are available for those who need to quickly pick up or drop off items or people. It is important to note that this does not permit long-term parking; rather, it allows temporary stopping to facilitate loading and unloading activities.

The other choices do not accurately reflect the function of a yellow curb. For example, indicating that parking is prohibited at all times or that loading and unloading is always allowed would not align with the specific purpose of yellow curb markings. Similarly, the option stating that time-limited parking is permitted does not apply, as yellow curbs are specifically designated for short stops related to loading and unloading only.
