Black Ice

It forms when temperatures are near freezing. Bridges and shaded areas freeze first. Roads may look only wet. Many cars warn the driver when the outside temperature is near freezing. If the car starts sliding on ice, avoid sudden braking or steering and keep inputs smooth. Bridges, shaded corners and dips near water are typical places where black ice forms first. Winter tyres improve grip but cannot prevent sliding on clear ice.

Water freezes in a clear layer.
