What roadway sign is best described as having five sides and is florescent yellow/green?

  1. A stop sign

  2. A yield sign

  3. A school zone sign

  4. A construction zone sign

The correct answer is: A school zone sign

The sign described as having five sides and being fluorescent yellow/green is indicative of a school zone sign. This specific design and color are utilized to alert drivers to the presence of a school area where children may be crossing the road, thereby prioritizing safety. The five-sided shape of the sign, known as a pentagon, is distinctive to signs that warn of school zones, making it easily identifiable to drivers. The fluorescent yellow/green color enhances visibility, especially in low-light conditions, which is crucial as children are often more vulnerable in these areas. This combination of shape and color serves to underscore the importance of caution in zones where children are frequently present. The other options, while also important roadway signs, are not characterized by these specific features.
