Black ice in my terminology is just dampness on a road that freezes
and becomes slippery. This is common this time of year.

Freezing rain is rain that falls through a cold layer of air and
becomes 'super cooled' It freezes on impact. When this condition
becomes severe it's called an 'ice storm'.

A spectacular case was the ice strom of 1998 in the Montreal area.
