What is a condition under which the driver of a school bus may stop driving?

• A. If a pupil misbehaves
• B. If visibility is low
• C. If the bus is crowded
• D. If road conditions are normal

Answer: (B)

Visibility is a crucial factor for safe driving, particularly when it comes to operating a school bus. When visibility is low, such as during fog, heavy rain, or snow, the driver cannot adequately see the road, other vehicles, or pedestrians. This diminished visibility increases the risk of accidents, making it unsafe to continue driving. Therefore, a driver should stop operating the bus until visibility improves, ensuring the safety of the students and others on the road.

In contrast, while misbehavior by a pupil may be distracting, it does not necessarily warrant stopping the bus unless it poses an immediate safety threat. A crowded bus can create logistical challenges but does not inherently prevent safe driving under normal circumstances. Normal road conditions imply that the driver can maintain safe operation, but if visibility is compromised, the ability to drive safely is severely impacted.
