Schroeder - The following is from The Old Farmers Almanac

Ice Thickness* Permissible Load
2 inches one person on foot
3 inches group in single file
7-1/2 inches passenger car (2-ton gross)
8 inches light truck (2-1/2-ton gross)
10 inches medium truck (3-1/2-ton gross)
12 inches heavy truck (8-ton gross)
15 inches 10 tons
20 inches 25 tons
30 inches 70 tons
36 inches 110 tons

*Solid clear blue/black and lake ice.
Slush ice has only half the strength of blue ice.
Strength value of river ice is 15 percent less.


I would add at least one extra inch to all measurements. Remember to stay away from partially submerged structure and trees . The sun warms the tree and will make the ice around it very weak. Stay safe!
