What is black ice?

• A. A thick layer of snow on the road
• B. A coating of ice that is nearly invisible to drivers
• C. A type of road hazard sign
• D. A temporary closure sign during winter

Answer: (B)

Black ice refers to a coating of ice that is nearly invisible to drivers, making it particularly hazardous. This type of ice forms when moisture on the road freezes, creating a smooth, transparent layer that adheres closely to the asphalt. The term "black" is used because the dark color of the road surface often shines through the thin layer of ice, making it difficult for drivers to see. This invisibility can catch drivers off guard, especially during nighttime or in conditions where visibility is reduced. Recognizing the presence of black ice is crucial for safe driving because it can lead to loss of traction, resulting in vehicles skidding or losing control. Awareness and caution in potentially icy conditions, particularly in shaded areas or during early morning and late evening when temperatures can drop, are essential for maintaining safety on the road.
