Make sure that your snowmobile is in tiptop condition. You don’t want to get stranded far away from civilization with a broken machine.
Do not snowmobile by yourself. Always go with another person on separate machine. If you get stuck, this person can help get you out. If you have an accident, he can go for help.
While you always hope that you won’t need it, be sure to always carry a first aid kit. Know some basic first aid skills, too, such as treating cuts. Know the signs of hypothermia and what to do if you, your passenger, or fellow snowmobiler starts to get it.
Carry a flashlight, a flare, some waterproof matches. If you plan on being gone only for a couple of hours, pack some high-energy snacks. If you’ll be gone longer, additionally pack food for a meal and plenty of water to stay hydrated.
Consider taking an insulated pad and an extra waterproof coat or jacket that could be used as a small emergency tent or shelter if you get stranded out in the elements.
Check the weather forecasts before you go. If heavy snow is predicted, do not stray too far from where your vehicle is parked. Stay in an area that is familiar to you so you won’t get lost if it begins to snow.
When you first start out, do not go fast. It may be very tempting! Take time to learn how to drive and handle your machine before you increase your speed.
Don’t drive over a frozen river or lake. The heavy weight of the machine could break through the ice and you could get stranded in icy cold water (which is very dangerous).
