What is the purpose of a pedestrian crossing sign?

The purpose of a pedestrian crossing sign is to indicate a place where pedestrians have the right of way. This sign alerts drivers that they are approaching an area where people may be crossing the street, and it emphasizes the need for drivers to yield to pedestrians at these designated crossing points. This safety measure is intended to reduce the risk of accidents and ensure that pedestrians can cross roads safely, thus encouraging responsible driving behavior.

The other choices pertain to different aspects of road safety and traffic management. Speed limit signs are focused on regulating vehicle speeds, while signs warning of school zones prioritize the safety of children during specific times. Signs indicating nearby bus stops serve public transportation purposes but do not influence pedestrian right-of-way.
