What is the purpose of new pedestrian and school zone signs?

The purpose of new pedestrian and school zone signs primarily revolves around enhancing safety for pedestrians, especially children, in high-traffic areas. These signs serve as warnings for drivers, alerting them to the presence of crosswalks and the potential presence of pedestrians. Such signage is particularly crucial in school zones, where children might be crossing the road before and after school. The visibility of these signs prompts drivers to reduce their speed and remain vigilant, thus significantly aiding in the prevention of accidents.

The other options, while relevant in different contexts, do not align with the primary function of pedestrian and school zone signs. Speed limit signs, for example, focus solely on controlling vehicle speeds rather than warning about pedestrian crossings. Similarly, regulating cyclist movements and designating parking areas are concerns addressed through different signage and laws, which don't specifically pertain to the purpose of pedestrian and school zone signs.
