Ahead, there is a reminder sign for school students crossing the road. What should you do?

Stop, wait for the sign to be retracted before continuing forward
If there are no children crossing the road, keep driving
If the children have already crossed the road, proceed immediately.

Option 1: "Stop and wait for the sign to be withdrawn before proceeding" is the correct practice according to New Zealand traffic rules. When the pedestrian crossing sign appears, vehicles in both directions must stop and wait; there is no concept of merely slowing down. You must stop and wait for the sign to be removed before proceeding.
