Final answer:
True, drivers must stop for a stopped school bus unloading children on a two-lane road to ensure child safety and adhere to traffic laws.
Step-by-step explanation:
The question asks whether a driver must stop when approaching a stopped school bus unloading children on a two-lane road. The answer is true. It is a standard traffic safety rule that drivers should stop on both directions of a two-lane roadway when a school bus is stopped with its red lights flashing and its stop arm extended, as this indicates that children are getting on or off the bus. Not only is stopping required by law to ensure the safety of the children, but failure to do so can result in significant legal penalties.
