Yes it is very clear.

"Anglers may only use one hook. An artificial lure is considered one hook. A treble hook, when not part of an artificial lure, is considered three hooks and is not legal."

I understand this law is in place to prevent snagging. But it also limits the use of quick strike rigs. Multi hook quick strike rigs for live or dead bait allow you to set the hook immediately--less likely for fish to swallow bait. Used to use them under a big bobber with a gigantic smelt or ciscoe for big nortens growing up. The Beavers is right How you get around the rule in MN is you have to add a small spinner above the hooks now it is considered a lure. Snagging is already illegal so I don't think the rule is necessary.

If you are fishing walleyes on a tip up you can add a stinger hook or second hook if you are using a small jig head or once again you have to add a spinner if you are just using a plain minnow to stay legal.
