What color are school signs typically?

School signs are typically fluorescent yellow-green or standard yellow, as these colors are designed to be highly visible and alert drivers to the presence of children and school zones. The use of these bright colors enhances visibility in various lighting conditions and increases awareness among drivers, promoting safety for students who may be crossing the road or waiting for buses. This color coding is standardized to ensure that all drivers recognize these important signals regardless of where they are, facilitating a safer driving environment around schools. The other colors mentioned are associated with different traffic signs and messages, which do not specifically indicate school zones or pedestrian areas.
