Invisible "black ice" catches drivers off guard on an interstate highway. Black ice forms from freezing rain, which creates a thin layer of ice on roadways that appears identical to wet pavement. You can prepare yourself for black ice by paying attention to the air temperatures before you get into your car. If temperatures are at or below 32° Farenheight (0° Celsius) and precipitation (rain or snow) has been present, expect roads to be icy!
