Investigators say speed and alcohol seem to be the biggest factors in snowmobile accidents.
According to the experts, you'll always want to think twice about racing in your sled, especially at night.
Your headlights only let you see about 220 feet in front of you, and once you hit 40 miles an hour, 220 feet is the distance it'll take you to come to a stop.
If you're riding on a lake, don't forget to be wary of everyone else who's out there.
"It is the law that when you come within 100 feet of any ice shanty or any person out on a snowmobile that you must be under ten miles an hour," says Sgt. Michael Lukas of the Portage County Sheriff's Department.
It's never a good idea to drink before you get out on your sled either, despite the fact that it won't affect your driving record if you get caught. You'll get fined more than $600 the first time, and you could go to jail for a month the next.
