Have fun but remember to stay safe while snowmobiling! Drowning is one of the leading causes of snowmobile fatalities. Wherever possible, avoid riding on frozen ponds and rivers because ice conditions are never guaranteed and can change in a period of several hours. If you must cross ice, stay on the packed or marked trail. Don’t stop until you reach shore. If you hit slush, don’t let off the throttle. If you are following someone who hits slush, veer off to make your own path. Consider carrying a set of picks that will help you grip the edge of the ice more easily. As a rule of thumb, “If you don’t know, don’t go.”

If you do break through the ice, don’t panic. Follow these self-rescue tips:

Kick vigorously into a horizontal position and swim to the nearest ice edge. 
Place hands/arms on unbroken ice while kicking hard to propel your body onto the ice, like a seal.
Once clear, stay flat and roll away to stronger ice.
Stand, keep moving and find shelter fast.
