When can you legally pass a school bus on the opposite side of the street?

Answer: B — Only when it is not loading or unloading children

You can legally pass a school bus on the opposite side of the street only when it is not loading or unloading children. This practice is put in place for the safety of children who may be crossing the street after getting on or off the bus. When a school bus has its stop arm extended or its red lights flashing, it indicates that children are either getting on or off the bus, and vehicles must stop to allow them to do so safely. If the bus is not actively loading or unloading children and you are on the opposite side of the street, you can proceed with caution. This rule reflects the importance of protecting children around school buses and emphasizes the driver's responsibility to be alert and vigilant in these situations.
