the.com/black ice

means A thin, nearly invisible glaze of ice on pavement that looks like just a wet patch — until your tires find out otherwise.

from Not a borrowing from another language but a plain descriptive name: the ice is so clear that the black asphalt shows through it, so it reads as 'black' road rather than 'white' ice. The term shows up in English by the mid-20th century in driving and weather reports, growing more common as cars, highways, and winter forecasting all spread together — a hazard that needed a name once enough people were driving fast enough to die from not seeing it.
