General ice thickness guidelines
According to the Minnesota Department of Natural Resources if new clear ice is less than 2″ – STAY OFF. If it’s 4″ ice fishing or other foot activities are OK. It needs to be 5″ for snowmobile or ATV. 8″-12″ is required for car or small pickup and 12″-15″ for a medium truck.
And if the Minnesota Department of Natural Resources doesn’t have something valuable to say about the topic of ice safety, I don’t know who would.
