People here call them tabs I guess? They are just the stickers you put on your license plate that you need to renew on a yearly basis, and the color of the sticker changes from year to year. Michigan sends you something in the mail so you can just renew it that way, but apparently my wife didn't send it in so that means we have to go to the Secretary of State's office. The SoS is a ****ty Michigan government office that handles things like vehicle and trailer registration, titles, drivers licenses, and other stuff that is usually really busy and there are always lots of interesting individuals there, kinda like the people you see using the public bus system around here.
Also, it's not soda guys, it's pop
