What is black ice?

Black ice refers to a thin layer of ice that forms on road surfaces, making the pavement appear wet and often blending in with the asphalt, which can be misleading for drivers. This phenomenon typically occurs when the temperature fluctuates around the freezing point, causing moisture to freeze on the road. Because it is often transparent or nearly transparent, drivers may not realize that they are driving on ice, which significantly increases the risk of losing traction and can lead to accidents.

Understanding black ice is crucial for drivers, particularly those operating large vehicles that require a longer stopping distance and are more challenging to control on slippery surfaces. Recognizing the presence of black ice helps drivers to take precautions, such as reducing speed and avoiding sudden maneuvers, to maintain control and increase safety while driving.
