I just found out that the Pioneer 500 must be registered/titled (with ATV sticker) in Missouri. They changed the law in 2014. Side by side/UTV over 50 inches (as stated by manufacturers) do not have to be but any UTV 50 inches or less must be registered/titled. I went to get mine registered at the local DMV back in April of this year and was told that since it's a UTV, it didn't need to be. I then got letters from the state saying that it does.
