Black ice

A photo of a small car and a semi truck in the background. Both are stuck in the median of a highway during winter.
Black ice is invisible ice that forms when air temperature is warmer than pavement.
Slow down and avoid applying brakes on ice.

What is black ice?

Black ice is actually invisible ice that is almost totally transparent. It can easily catch drivers off-guard and cause crashes.

 

How and where does black ice form?

Black ice forms when the air temperature is warmer than pavement, which causes moisture to rapidly freeze and creates a thin, transparent layer of ice on the roadway.
