Here in Florida, you cannot register a side by side for street use. Roxors are assigned a VIN that states it being manufactured as a side by side. You can register a golf cart though. Most side by sides here in Florida on the street are registered in a different state with a motorcycle plate.
My Roxor was made street legal in Michigan and afterward the Michigan DMV assigned it an Assembled Vehicle VIN. With the assembled vehicle VIN you get an automotive plate, not a motorcycle plate. When I brought the Roxor to Florida, the DMV transferred the Roxor and gave me a full automotive plate.
