What does a yellow-green sign typically indicate?

A yellow-green sign is specifically used to indicate areas where there may be increased pedestrian activity, such as school zones or pedestrian crossings. This color combination is designed to draw attention and alert drivers to the presence of children and pedestrians, reminding them to exercise caution and reduce their speed in these areas. The use of yellow-green for these signs enhances visibility and serves as a warning for drivers to be extra vigilant for potential hazards involving pedestrians.

In other contexts, while construction zones may use orange signs to signal work areas, hazardous conditions might also utilize different caution colors such as bright yellow or white, and speed limit zones are typically marked with standard white signs. Thus, the distinctive yellow-green color specifically communicates the importance of pedestrian awareness and safety.
