What color vests do flagpersons typically wear?

Flagpersons, who manage traffic and ensure safety in construction zones or during road work, typically wear vests that are orange, yellow, or fluorescent. These colors are chosen because they offer high visibility. The bright hues stand out against most backgrounds, making it easier for drivers to see the flagperson from a distance, especially in varying weather conditions or during low-light situations.

Using these colors effectively communicates the presence of a person directing traffic, which is essential for maintaining safety in potentially hazardous environments. Other colors, such as red, blue, or green, do not provide the same level of visibility and are not standardized for this specific purpose, making them unsuitable for flagperson vests.
