Road conditions play a significant role in vehicle handling, primarily by reducing traction and control. When the road surface is wet, icy, or uneven, it can diminish the tires' ability to grip the road effectively. This loss of traction can lead to skidding, longer stopping distances, and difficulty in maintaining control when steering or changing lanes.

For instance, on wet pavement, the water can create a layer between the tires and the road, which reduces the friction necessary for optimal vehicle control. Similarly, if roads are covered in snow or ice, the likelihood of losing control is even greater due to extremely limited traction. Poor road conditions, such as potholes or loose gravel, can also disrupt the vehicle's handling and stability. Understanding how these factors influence traction helps drivers make safer choices and be more prepared for challenges while driving.
