Every one knows what a snow plough is. No? Then let me explain

A Snow Plough is a special type of truck used in winter for snowing off roads and sideways. An ordinary truck or car can become asnow plough by mounting a special shovel in front of the bumber of that car. But we must remember that the car has to have enough power to move the snow.

Without snowploughs cities would be baralized after heavy falls of snow.
