With the Piaggio MP3, the T-Rex, the Bombardier Can-Am Spyder and more three wheelers inevitably on the way, state laws will have to work to keep up, figuring out how they want to classify them for licensing and registration. Delaware now has a law pending that will require operators of these vehicles to have a motorcycle endorsement which takes away the guesswork, at least in that state. Up until now, a regular driver’s license was all that was needed to legally drive any of these.
With the Piaggio, you are riding a vehicle very similar to a regular scooter but with the T-Rex, for instance, you’re sitting inside like a car and other than being powered by a motorcycle engine, it has little similarity to any two wheeler. Unless each vehicle is going to be classified by the department of motor vehicles separately, a law classifying 3 wheelers one way or the other is necessary so everyone knows where they stand. I’m guessing these will be classified as motorcycles for licensing more often than not wherever no law is presently in place.
