What is "black ice"?

"Black ice" refers to a patch of clear ice that often appears wet to drivers. This type of ice is particularly dangerous because it is difficult to see, blending in with the road surface, and can lead to unexpected loss of traction for vehicles. Because it is transparent, drivers might not recognize the hazard until it’s too late, leading to potential skidding or accidents.

Options that describe other conditions, such as a slippery surface made of snow or a dangerous road coating, do not capture the specific characteristics of black ice, which is clear and often deceptive in appearance. Similarly, the option suggesting ice forms on only one side of the road does not relate to the properties of black ice, as it can appear anywhere on the roadway, regardless of sides. Understanding the nature of black ice is essential for safe driving, especially in winter conditions.
