Which factor influences the traction of a bus when speed increases?

Traction refers to the grip that the tires of a bus have on the road surface, which is crucial for safe driving, especially as speed increases. When the speed of a bus increases, the dynamics of traction change, often leading to a decrease in traction due to several reasons, such as increased centrifugal force in turns and potential loss of contact with the road surface if conditions are not optimal.

As speed rises, the tires may have a harder time gripping the road due to factors like inertia and the natural shift in balance. This diminished traction can make it more challenging for the driver to control the vehicle and can increase the chances of skidding or losing control in specific conditions like wet or icy road surfaces. Thus, understanding that traction decreases with higher speeds emphasizes the importance of careful driving and adherence to speed limits, especially in a bus with the responsibility of transporting passengers safely.
