Now that ice is forming, and we undoubtably will start to hear about vehicles, ATV's, snowmobiles, and people going through the ice.
Here is info from the State of Minnesota.
2 inches or less: KEEP OFF!!!!!
4 inches: ice-fishing or other on foot activities
5 inches: Snowmobiles or ATV's
8-12 inches Cars
12-15 inches Medium Truck

When in doubt, STAY OFF. Be safe, and don't take the next heavier vehicle out on the ice to test it
.
Bottom Line (yes I am shouting) BE SAFE!!!!!!!!!
