What color are standard school zone signs?

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

Answer: (A)

High-visibility warning color is used for school zones to quickly grab a driver’s attention because it signals caution in areas with children. Fluorescent yellow-green, often called safety-yellow, is highly noticeable in daylight and across different weather conditions, making it easier to spot early and slow down in time. Other colors serve different purposes: red and white indicate mandatory actions or stops, blue with white letters points to services, and green with white letters provide directional guidance. None of those convey the same urgent warning about school children as clearly as safety-yellow.
