Just realized this is an old thread. As of 2017, those moped laws read exactly the same as FL. Sure, I ride my MB everywhere around work and race tracks, and never been bothered.........but .....if there was an accident or the like, there may be issues. If one is hurt, there's no coverage etc.
As I said in another thread, I've been riding off road vehicles, on the roads, and as long as I was respectful, never once got in trouble. If anything, chatted with officers. Tractors, double trailers, back hoe, motorized bike, go karts, even once stopped in a race car on a test run, I was passenger...driver turned out had suspended DL. They laughed, told us not to test on public roads, have a nice day.
