Question

what is true about this school speed limit sign? you must go at least 20 mph at all times. you may not go faster than 20 mph when there are children around. the speed limit is always 20 mph on this entire road. school speed limit 20 when children are present

Explanation:

• Analyze the first option: School speed limit signs are for maximum speed, not minimum, so "at least 20 mph" is wrong.
• Analyze the second option: The sign says "WHEN CHILDREN ARE PRESENT", so the 20 mph limit applies when children are around (present), meaning you can't go faster than 20 mph then. This matches the sign's meaning.
• Analyze the third option: The sign has the condition "WHEN CHILDREN ARE PRESENT", so the limit isn't always 20 mph on the entire road, only when children are present.

Answer:

B. You may not go faster than 20 mph when there are children around.
