What type of weather conditions require a school bus driver to increase caution?

In conditions characterized by rain and snow, the school bus driver must exercise increased caution due to several factors associated with such weather. These conditions can severely affect road traction and visibility. Rain can create slippery surfaces, especially when oil and water mix, which can lead to challenges in braking distances and steering control. Snow often covers the roadway, reducing grip and making it more difficult to navigate turns and stops safely.

Additionally, rain and snow can lead to reduced visibility, making it harder to see other vehicles, road signs, or pedestrians. Furthermore, during snowy conditions, other drivers may also struggle with their vehicle control, which can increase the risk of accidents. Consequently, the driver needs to adjust their speed, increase following distances, and be more vigilant while driving to ensure the safety of all passengers onboard the bus.
