What is gritting the road?

Gritting involves spreading rock salt on the roads to prevent ice forming and, during heavy snowfalls, snow ploughs may be used to clear snow. Salting is done when it is not raining to avoid the grit being washed away. If rainwater freezes quickly ice can form before our teams have completed their routes.
