School children have just alighted and some start to cross in front of your autobus. What should you do?

1. Pull away promptly so the bus no longer blocks their view
2. Wave them across while rolling, because you can see both directions from the cab
3. Sound the horn and continue; children must wait on the kerb after alighting
4. Keep the bus stationary with doors closed until the crossing children are clear, and watch the front corners where small children disappear
