What factor affects friction and traction on the road surface?

Weather conditions significantly impact friction and traction on the road surface. When it rains, snows, or the road is icy, the surface becomes slippery, which reduces grip between the tires and the road. This decreased friction can lead to longer stopping distances and an increased chance of skidding. Conversely, dry and clear weather typically provides better traction, allowing for optimal handling and braking performance.

While other factors such as the driver's skill play a role in how effectively they can respond to changes in traction, they do not directly alter the physical properties of the road surface itself. Similarly, the type of fuel used in the vehicle does not affect the friction between the tires and the road. The color of the vehicle is entirely unrelated to friction and traction, as it does not influence the surface material or the tire performance.
