When must you intervene as driver of a school bus while you are driving?

As a driver of a school bus, it's essential to ensure the safety of all children on board. The correct response involves intervening in specific situations where children's behavior may pose safety risks.

Entering the marked off area indicates a zone where children are either getting on or off the bus, and as a driver, you must be vigilant to their movements and surroundings.

Children standing on the seats could lead to accidents or injuries, as they may lose balance and fall. Thus, intervention is necessary to maintain a safe environment.

The act of changing places is not included in the correct combination because it may not represent a direct safety hazard that requires immediate intervention.

Overall, selecting all relevant scenarios is crucial to ensure the well-being of children and comply with German traffic regulations. Always prioritize safety and be proactive in monitoring children's behavior while driving.
