Who has priority at a crosswalk?

In a crosswalk, pedestrians crossing within the designated area have the right of way. This means that vehicles must yield to pedestrians who are already walking in a crosswalk or who are about to enter it. The traffic laws are designed to protect pedestrians, as they are more vulnerable than vehicles. This priority is established to ensure the safety of those on foot, allowing them to cross the street without the immediate threat of approaching vehicles.

Now, considering the other choices, vehicles over pedestrians would contradict the laws designed to prioritize pedestrian safety at crosswalks. Speeding vehicles have no special consideration at crosswalks as they may pose a higher risk to pedestrians, and only buses do not have any particular rights that would outweigh those of pedestrians in this context. Thus, it reinforces the importance of allowing pedestrians to cross safely and confidently.
