The Minnesota DNR is urging drivers to use caution when heading out onto frozen lakes and rivers. Lisa Dugan is with the DNR.

“Stay off the ice at night, especially if it’s foggy or there are snowfall conditions, it makes it hard to see any areas of hazard that might be ahead of you,” said Dugan.

The warning comes after a truck fell through the ice on Lake Hanksa this week. The Brown County Sheriff’s Office says the two occupants of the truck escaped through the windows. Authorities remind people ice thickness is unpredictable. The Sheriff’s Office says where the vehicle went through was about seven inches thick yesterday and one hundred yards away, 15 inches of ice was detected. They add retrieval cost is estimated to be around ten-thousand dollars.
