Black ice is a thin layer of ice that forms on roadways, making it nearly invisible to drivers. It typically occurs when temperatures drop and moisture freezes, often in shaded areas or during early morning hours. This can create hazardous driving conditions, as vehicles may lose traction unexpectedly. To stay safe, drivers should be cautious in cold weather and watch for signs of black ice, such as wet-looking pavement or areas where snow has melted. Reducing speed and maintaining a safe distance from other vehicles can help prevent accidents when encountering this dangerous condition.
