You CAN open carry in a vehicle without a permit, but your weapon needs to be visible from outside the vehicle.
I would not risk it unless you wanted to challenge that unconstitutional infringement. There was a ruling on that I read but for the life of me, I can't find it. For now I suggest you either pay the bribe money demanded by the state to exercise a right you already have. Unless you've got a ton of money, in which case take no notice and try to fight the government. Best of luck though, you'll need it
Why would you cut and paste one sentence out of my post when the rest of the paragraph said basically exactly what you said? I'm not sure if you are agreeing with me or disagreeing? I could cut and paste words out of any post here and make it say anything I wanted to.
You can open carry without a license, loaded in a car, truck, boat, motorcycle, lawn mower, bicycle, even a personal aircraft in Wisconsin. The wisdom of doing that in a car on the highway is up for debate, for sure. I have done all of the above! Look on page 44 of the links FAQ.
To the OP, start reading the DOJ FAQ at the bottom of page 21. Page numbers are at the bottom of the page and NOT the numbers generated by the browser. The first 21 pages are the index and then rules regarding law enforcement officers.
OC vs CC page 28
Schools page 32-36
Signs page 38
Prohibited places page 40
TRANSPORTING page 44
I read through this every once in a while when I am bored and lonely. It's kinda dry, but it is understandable. Sadly, they don't link to any citations in the actual law, but it is put out by the WI DOJ so I suppose it is about as close as you can get.
