  2. B
    Maintain 20 mph continuously during standard school hours, regardless of whether any children are visible.
  3. C
    Treat the sign combination as an absolute stop requirement before proceeding through the school zone.
  4. D
    Drive at the regular posted street speed limit unless an electronic yellow beacon is actively flashing.

Answer

Reduce your speed to 20 mph only when children are visible on or adjacent to the roadway, sidewalks, or school grounds.
A yellow-green pentagon sign marks a school area. When combined with a plaque stating 'SPEED LIMIT 20 - WHEN CHILDREN ARE PRESENT', drivers must slow down to 20 mph whenever children are visible anywhere on or near the street, crosswalks, or adjacent school property.

Step-by-Step Solution

1
Identify the primary warning sign and its supplemental plaque.
The pentagon shape indicates a school zone, and the supplemental plaque defines the specific speed condition ('SPEED LIMIT 20 - WHEN CHILDREN ARE PRESENT').
Supplemental plaques modify or define the exact legal scope of school zone warning signs.
2
Evaluate the condition required to trigger the lower speed limit.
The speed limit drops to 20 mph upon observing children walking, playing, or waiting near the roadway.
The phrase 'WHEN CHILDREN ARE PRESENT' applies dynamically based on visual presence rather than strictly fixed clock hours or flashing signals.
