The requirement to stop for a school bus is specifically focused on the safety of children who are either getting on or off the bus. When a school bus is loading or unloading children and its stop sign is extended, it indicates that children may be entering or exiting the bus, which creates a significant risk if vehicles do not stop. Stopping ensures that these children can do so safely without the danger of oncoming traffic.

Other options do not represent the correct conditions for stopping. For instance, if the bus is in motion, it is typically not necessary to stop, as children are not being actively loaded or unloaded at that time. Similarly, a bus driver signaling a driver to stop is not a standard requirement; it's the presence of the stop sign that is the key determinant. Lastly, driving under 25 mph is not a relevant condition for determining whether you must stop for a school bus; speeds do not dictate the requirement to stop when the bus is loading or unloading.
