What is the shape and color of a school crossing sign?

The school crossing sign is characterized by its distinct yellow pentagon shape, which is designed to attract the attention of drivers and alert them to the presence of children in the area. The color yellow is commonly used for cautionary signs, conveying the need for drivers to slow down and be vigilant, especially in areas likely to have pedestrians, such as near schools.

The use of a pentagon shape is specifically significant as it is reserved for school-related signs. This shape, combined with the bright yellow color, ensures that the sign is easily recognizable and stands out against its surroundings, helping to improve safety for children crossing the street.
