On which type of road are skids likely to occur?

Skids are particularly likely to occur on roads where snow has become packed. When snow is packed down by vehicle tires, it can create a slick surface that reduces tire traction. This condition is often exacerbated by the cold temperatures, leading to icy patches that can cause vehicles to lose control.

While a newly paved road may initially present a smooth driving surface, it typically does not have the same hazards associated with packed snow. New pavement can also provide good traction unless there are other factors involved, such as rain or other substances on the roadway. Thus, the situation with packed snow significantly increases the risk of skidding, as the surface can become slippery and uneven, often leading to dangerous driving conditions.

Therefore, the road where skids are most likely to occur is indeed the one with packed snow, making it crucial for drivers to exercise caution in such conditions.
