What color are standard school zone signs?

• A. Fluorescent yellow-green (safety-yellow) signs.
• B. Red and white signs.
• C. Blue and white signs.
• D. Black and yellow signs.

Answer: (A)

Fluorescent yellow-green, often called safety-yellow, is used for standard school zone signs because it stands out quickly to drivers in a variety of lighting and backgrounds. This bright color is chosen to grab attention and warn drivers that children may be nearby, prompting slower speeds and extra caution. Other colors serve different purposes—red and white for regulatory commands, blue and white for informational signs, and black-on-yellow for some generic warnings—but they aren’t the established color for school zone warnings. So the recognizable color you’ll see for school zones is fluorescent yellow-green.
