When approaching a school bus with its stop arm extended, the correct action is to stop at least 20 meters away. This is crucial for ensuring the safety of children who may be boarding or disembarking from the bus. The stop arm and flashing lights indicate that the bus is picking up or dropping off passengers, and it is a legal requirement for vehicles to come to a complete stop.

Stopping at least 20 meters away provides a safe distance, allowing any children to cross the road without the risk of being harmed by vehicles not adhering to the stop signal. This response not only complies with traffic laws but also upholds the responsibility of drivers to protect the most vulnerable road users—children.

Other actions, such as slowing down and proceeding cautiously, are insufficient because they do not guarantee the safety of children in the vicinity. Sounding the horn is inappropriate, as it may startle children and lead to unpredictable behavior. Continuing to drive at normal speed is unsafe and against the law in this scenario.
