Never Ride Alone
It is strongly recommended that you always use the buddy system and never snowmobile alone.
If you do choose to ride alone, be doubly certain to follow all safety procedures including using the Pre-ride Checklist
and ensuring you have your tool kit, safety equipment, emergency kit, and personal items kit with you before you leave.
Always let someone know when you are riding alone, exactly where you are going, when you will return and absolutely never deviate from your stated trip plan so they know where to look for you if you are over-due.
