Final answer:
A 'Pedestrian Crossing' sign is a traffic and pedestrian safety sign, typically yellow in color, signaling drivers to watch for and yield to pedestrians.
Step-by-step explanation:
The type of sign that says, "Pedestrian Crossing: Watch out for people who might walk or run in front of you. Pedestrians have the right of way and you may have to stop for them," is a traffic and pedestrian safety sign. These signs are typically yellow and feature an image of a pedestrian to alert drivers to the potential presence of people crossing the road. This sign serves as a reminder that drivers should be vigilant for pedestrians and be prepared to yield to them, ensuring pedestrian safety especially around areas with high foot traffic like schools and campuses. In areas where pedestrian safety is compromised due to high vehicle speeds or large volumes of traffic, the installation of a traffic signal can help manage vehicle flow and provide designated crossing times for pedestrians.
