There's no law in Michigan and other states that says you cannot drive legally without a shirt.
My brother in Michigan drives without a shirt all the time in the summertime and even sometimes drives around in his boxer shorts as well.
He's been pulled over for other things and has been in his boxer shorts and no shirt and sometimes just shorts and no shirt and he's been just fine.
The cops have never said anything about the way he was dressed.
If you want to drive without a shirt in Michigan or other states you can legally do so without any issue.
