In a school zone with reduced speed signs, when must you obey the reduced speed limit?

• A. Only during wet weather.
• B. During school hours or as signed.
• C. Only when children are present.
• D. Any time of day.

Answer: (B)

The reduced speed in a school zone is in effect only when the signs indicate it. It’s typically limited to school hours or other times shown on the posted signs, so you must slow down during those times and stay at that limit until you pass the end of the zone or the times end. This ensures lower speeds when children are most likely to be nearby, but not outside those designated times.

The other scenarios don’t fit because the sign dictates when the limit applies, not weather, whether children are present, or an all-day rule.
