You might want to some further research the definitions of the various classes of vehicles; particularly motorcycles. nojoke
While it's certainly not impossible for what you're saying to be true: I would want to make sure that I've got my ducks in a row, before arguing with a Police Officer over what my vehicle is.
EDIT: After a
brief search of Nevada's DMV laws: they state that if a motor vehicle has three wheels or less; it's a motorcycle. :dontknow:
I didn't have the inclination to dig a whole lot deeper, so there might be something in the fine print that changes this...
