Do you need a drivers license to drive a vespa?

In California, you need what's known as an M2 license (motor-driven cycles). The requirements are listed below and I suspect most US states will have similar requirements (check your state DMV for more info, your mileage may vary) To apply for a motorcycle Class M1 or M2 permit, you will need to: * Be at least 15 ½ years of age * Visit a DMV office * Complete application form DL 44 * Have your parents' or guardians' signatures * Give a thumb print * Have your picture taken * Submit proof you have completed both driving education and driver training. * Present an acceptable birth date/legal presence document. * Provide your true full name. * Provide your social security number. * Pay the required application fee. * Pass an vision exam. * Pass a traffic laws and signs test. * Pass an additional law test of motorcycle driving rules. OR * Show your California driver license, if you have one issued to you.  more

In the U.S. does vary according to state, but most require a motorcycle license if the engine is greater than 50cc. Here in Arizona, you need a motorcycle permit if it is less than 50cc to ride on the streets legally and have it registered. That test involves simply reading a book and taking a computer test at the DMV (and something like Old School's answer). If you have a vespa with greater than 50cc engine, you are then required to do the riding test as well.  more

If it's less than 49 ccs then you do not need insurance but you still need a license and a plate.  more
