When snow covers the ground and the sky is grey, you must change the kind of transport you use to get from one point to another. When you do not have to hurry, you can use skis or a sled, but another kind of transport is snowmobiling. It is powerful and can pass various obstacles such as mounds of snow or small crevices.
Driving a snowmobile is not easy, because you can go wrong if you drive on ice or sleet.
A snowmobile is also known as a snow scooter.
In ski resorts, you can see many people using snowmobiles.
