What is 'Black Ice'?

Black ice refers to a thin layer of ice that forms on roadways and is often nearly invisible to drivers. This type of ice typically occurs when moisture on the road freezes, creating an extremely slick surface. Because it is often transparent and has a dark appearance that blends with the asphalt, many drivers may not notice it until it's too late, making it particularly hazardous.

Understanding the nature of black ice is crucial for safe driving, especially during colder months or in areas where temperatures fluctuate around the freezing point. Proper awareness can help drivers take precautions, such as reducing speed and increasing following distances when conditions are favorable for the formation of black ice.

In contrast, rain mixed with oil can create slippery conditions, but this is not the same as black ice. Similarly, ice on snow-covered roads may be visible and can be managed differently than the danger posed by black ice. Water pooling on the road surface can also create hazards, but again, it differs fundamentally from the stealthy presence of black ice.
