Use a sled with runners and a steering mechanism, which is safer than toboggans or snow disks. Sled in well-lighted areas when choosing evening activities. Drinking before or during snowmobiling can impair judgment, slow reaction time, increase likelihood of hypothermia. Speed plays a part in nearly every fatal snowmobile crash. Bring first-aid kit, flashlight, waterproof matches, knife and compass.
Fatigue can harm coordination, judgment.
Avoid ice, particularly when uncertain of thickness. Never travel single file when crossing water bodies. Use a full-sized helmet and goggles or a face shield. Clothing should be windproof and water repellent, worn in layers and just snug enough to avoid catching in the machine. When necessary to cross one, come to complete stop, listen, use hand signals.
