Final answer:
When approaching a school bus with its yellow hazard lights flashing, you should slow down and proceed with caution, ensuring the safety of students getting on or off the bus.
Step-by-step explanation:
When approaching a school bus that is stopped off the roadway with its yellow hazard lights flashing, you should slow down and proceed with caution (option A). The purpose of the yellow hazard lights is to alert other drivers of a potential hazard, such as students getting on or off the bus. It is important to remain vigilant and be prepared to stop if necessary. Passing the school bus (option B) or speeding up (option C) can be dangerous and put the safety of the students at risk. Ignoring the school bus (option D) is not the appropriate response as it is essential to follow traffic laws and prioritize the safety of others.
