One of the worst situations any driver can encounter is a surprise. When that surprise is a total loss of traction or grip the results are frightening. This can easily lead to a crash. The dictionary describes black ice as “a thin, nearly invisible coating of ice that forms on paved surfaces.” It can be all but invisible, and can blend in nicely with grey or darker surfaces. Early and late winter, are the most likely periods when we’ll encounter black ice. It usually forms at dawn or just prior to dusk. A millimetre-thin layer of moisture on the road is created by a difference between air and surface temperatures — condensation.
This tiny and often invisible layer of moisture can also appear at other times of the day, and year as well. But it is particularly prominent at this time when the sun still has some punch but the ground is cool.
