In an astonishing video uploaded on to Twitter, a young passenger winds down her windscreen to reveal a sheet of ice.

She touches the ice with her finger and it shatters, much to her amusement.

Freezing rain is the name given to rain which solidifies on contact with freezing surfaces - such a car window in current conditions.

Unlike sleet, which is a mixture of rain and snow, ice pellets and hail, freezing rain is made entirely of liquid droplets.
