A school group is boarding your autobus from a crowded kerb. What is the safest sequence?

1. Keep rolling at walking speed with the front door open so the teacher can count children
2. Stop fully, secure the bus, open doors only when the door area is clear, and do not move until every child is inside and the doors are closed
3. Board from the offside traffic lane so children stay away from the cycle track
4. Use the horn continuously so following cars do not pass
