During which weather condition should a bus driver be extra cautious?

Bus drivers need to be extra cautious during rain, snow, and fog because these conditions significantly impact visibility and road traction. When it rains, water can create slippery surfaces that increase the risk of skidding and reduce stopping distances. Snow and ice further exacerbate these issues by making roads very hazardous, requiring drivers to adjust their speed and increase following distances. Fog reduces visibility dramatically, making it difficult to see other vehicles, road signs, and potential hazards. All of these factors together necessitate heightened awareness and careful driving habits to ensure the safety of all passengers and other road users. Meanwhile, sunny weather and clear skies typically present fewer hazards for bus drivers, although caution is still necessary in any driving condition. High winds can also pose risks, but they are often more manageable than the compounded dangers presented by rain, snow, and fog.
