Does the Adhesion Increase or Decrease on Ice and Snow Roads?

[LeMichael]

When driving on ice and snow roads, the road adhesion decreases. Additional Information: I. Introduction to Ice and Snow Roads: Generally refers to snow-covered roads, compacted snow roads, snow-turned-ice roads, and ice roads. The most significant characteristic of ice and snow roads is their low adhesion coefficient, which is only 10%~20% of that of dry and well-paved roads. A low adhesion coefficient results in reduced adhesion. II. Ways to Improve Vehicle Adhesion on Ice and Snow Roads: 1. Use snow tires. 2. Utilize four-wheel drive. 3. Use snow chains. Note: Changing to snow tires is the best method as it directly increases the adhesion between the tires and the road. Snow chains are less commonly used due to their inconvenient installation and potential damage to both tires and road surfaces.
