Answer

Reduce speed to the posted school zone limit of

20\text{ mph}

or lower until entirely clear of the school zone.

When school zone warning lights are actively flashing, drivers must immediately reduce speed to the posted school zone speed limit (typically

20\text{ mph}

) and maintain that speed until reaching the end of the school zone.

Step-by-Step Solution

Identify active regulatory traffic indicators

Recognize that active flashing beacons on a school zone speed sign signal a legally active speed reduction.

School zone limits are enforced when flashing lights are operating.

Adjust vehicle speed accordingly

Decelerate to

20\text{ mph}

or lower prior to entering the school zone boundary.

Drivers must maintain the reduced speed through the entirety of the designated zone for safety.
