What is indicated by a sign that is fluorescent yellow-green?

A sign that is fluorescent yellow-green is specifically used to alert drivers to areas where there are school zones and pedestrian crossings. This bright color is selected because it enhances visibility, especially in low-light conditions, thereby promoting the safety of children and pedestrians who may be present in areas where traffic needs to slow down. The goal of this color is to catch a driver's attention and to signify an increased risk of pedestrian activity, which is crucial for ensuring safety in regions where people, especially young children, are likely to be crossing the road.

In contrast, other colors like orange are typically utilized for construction zones, while wildlife crossings may be indicated by different colors such as yellow or caution colors. Speed limit zone signs usually feature white backgrounds, and their purpose is to convey regulatory information rather than the specific alerts that yellow-green signs provide.
