Final answer:
A driver should have a clear view of the road for at least 200 meters in each direction when stopping to unload passengers from a school bus to ensure safety.
Step-by-step explanation:
When you stop to unload passengers from a school bus, it is imperative that you ensure a safe environment for all. For maximum safety, it is generally recommended that you have a clear view of the road in each direction. While specific distances may vary based on jurisdiction, a common guideline is to have a clear view of at least 200 meters. This distance allows a driver enough time to react to oncoming traffic or any other potential hazards. Ensuring this clear view minimizes the risks for both the passengers disembarking and the other vehicles on the road.
