How does gritting the roads work?

Gritting roads involves spreading a mixture of salt and grit (sand or aggregate) onto the road surface to improve traction and prevent ice formation during cold weather. The salt lowers the freezing point of water, helping to melt existing ice and snow. Grit provides additional traction for vehicles, reducing the risk of accidents. Gritters are typically equipped with a spreader system that disperses the material evenly across the road as they drive.
