What is the condition of ice that is deemed too unsafe for riding?

The condition of ice that is deemed too unsafe for riding is indicated by a thickness of 10 centimeters or less. Ice at this thickness does not provide sufficient structural integrity to support the weight and movement of a snowmobile safely. Riding on such thin ice poses a significant risk of breaking through, resulting in dangerous situations. In contrast, thicker ice, such as that which is 15 centimeters or more, is generally considered safer for riding, as it is less likely to collapse under the weight of a snowmobile. Additionally, 20 centimeters or more typically indicates a safer riding condition, further emphasizing that ice must reach a minimum thickness to be deemed secure for snowmobiling activities.
