What does a white-painted curb indicate?

Answer: A — Loading zone for passenger loading and unloading

A white-painted curb indicates that the area is designated for passenger loading and unloading. This means that vehicles may stop at this curb temporarily to allow passengers to enter or exit. It is important to note that this is not a zone for parking; it is meant for quick stops only, ensuring that other vehicles can continue to flow smoothly through the area. This regulation helps manage traffic effectively in busy areas, providing a safe space for passengers while preventing longer-term parking that could lead to congestion.
