Authorities warn of thin ice

Law enforcement is warning Minnesotans to use caution when going out onto frozen lakes. 

According to authorities, ice should be 4 inches thick for walking, 5–7 inches for snowmobiles and ATVs and 8–12 inches for vehicles. 

They also warn not to go onto ice alone, avoid cracks and moving water. 

If you fall into the water, authorities say to remain calm, try to pull yourself back onto the ice by kicking your legs and using your arms to pull yourself onto a solid surface. Then you should crawl away from the hole in the ice on your stomach to distribute your weight evenly.
