During what condition is it particularly important for bus drivers to be vigilant?

Being vigilant during rainy or foggy weather is crucial for bus drivers because these conditions significantly impact visibility and road traction. Rain can create slippery surfaces, increasing the stopping distance required and making it easier for the bus to lose control. Fog reduces visibility, making it difficult to see other vehicles, pedestrians, or signals, which can lead to dangerous situations. In these weather conditions, bus drivers must be particularly attentive to their surroundings, ensure they are operating at safe speeds, and maintain a safe following distance to respond appropriately to any potential hazards or unforeseen situations.

In contrast, while sunny afternoons may seem straightforward, they can introduce glare that affects visibility, and school holiday breaks might see reduced traffic, but that doesn't necessarily require heightened vigilance. Similarly, traffic jams demand focus on the immediate surroundings for safety but do not present the same inherent risks associated with adverse weather conditions.
