Which of the following is NOT a position of pedestrians?

The correct answer indicates a position that does not typically involve pedestrians in a direct interaction with bus operations. A designated pickup zone is specifically meant for the purpose of allowing pedestrians to board or alight from vehicles safely. This area is inherently designed to accommodate the movement of pedestrians in relation to public transportation, especially buses. It serves as a controlled environment where pedestrians can expect to safely enter or exit a bus, making it an actively utilized space for them.

Conversely, the other options represent scenarios where pedestrians might be positioned in relation to a bus but can also indicate moments of danger or confusion. For example, being on board refers to passengers already inside the bus. Being in front of the bus could imply a critical risk, as it places a pedestrian dangerously close to the bus’s path. Boarding or alighting describes the action of getting on or off the bus, which occurs in various locations, including designated zones but also potentially in unsafe settings. Therefore, the designated pickup zone is the only option that clearly identifies a safe and appropriate position for pedestrians concerning bus operations.
