There are a few terms that might be used to describe ice on a road.
* **[]{}** (literally "road surface freezing")
* **** (from the German word "Eisbahn")
* **** (probably the closest to what you're looking for)
The first two refer to any ice on the road, whether it's visually apparent or not. The last one is transparent ice on the road.
I found these on the Wikipedia article for , which I navigated to by searching for "black ice" on the English language Wikipedia and then changing the language for the article to Japanese.
