After stopping for a school bus, when is it safe to proceed?

The correct answer is based on the key safety principle of ensuring that all conditions are safe before proceeding, especially when it involves the safety of children. After stopping for a school bus, it is essential to wait until the bus has resumed motion and the red lights have stopped flashing.

When the bus is stopped with its red lights flashing, it indicates that children may be entering or exiting. Therefore, proceeding before the bus has moved and the lights have stopped could put children at risk. The flashing lights serve as an important warning that it is not safe to continue driving.

This answer emphasizes following traffic laws designed to protect pedestrians and specifically children, who may unexpectedly cross the road in front of the bus. Proper adherence to these rules contributes significantly to road safety.
