Which signage specifically indicates a school zone?

The signage that specifically indicates a school zone is characterized by a yellow and black sign featuring a school symbol. This color combination is intentionally chosen for its visibility and clarity, serving as a warning to drivers that they are approaching an area where children may be present. The yellow color denotes caution, while the black symbol adds visibility against the bright backdrop of the sign.

In contrast, other color combinations depicted in the alternative options are associated with different meanings. A green and white sign typically designates informational or directional purposes, while a red and white sign conveys prohibitive messages such as stop or yield. Blue signs often mark services or facilities, rather than specific warning or caution areas like a school zone. By using yellow and black for school zone signs, it maximizes driver awareness to promote safety in areas frequented by children.
