What is a key factor in maintaining control of the bus in adverse conditions?

Reducing speed and increasing following distances is essential for maintaining control of the bus in adverse conditions. Slower speeds allow the driver to react more effectively to unforeseen circumstances, such as slippery roads or reduced visibility, which often accompany adverse weather conditions. By increasing the following distance, the driver has more time to respond to the actions of vehicles ahead, which can be particularly unpredictable in challenging conditions. This approach significantly enhances the driver's ability to manage the bus safely and avoid potential accidents or loss of control.

In contrast, accelerating rapidly could lead to loss of traction or control, especially on slippery surfaces. Maintaining a steady speed may not provide enough adaptability to changing road conditions. Using the bus’s horn frequently may not have any beneficial effect on controlling the vehicle and could distract other drivers and pedestrians instead of contributing to safe driving practices. Thus, the focus on reducing speed and increasing following distances is critical for ensuring safety and control while navigating adverse situations.
