N.H. Rev. Stat. § 263:31
The department shall cause to be issued a motorcycle license for persons without a driver's license or an endorsement on the driver's license for persons who have a driver's license, for all applicants who successfully complete the requirements for a motorcycle license. The department shall cause to be issued a restricted motorcycle license for persons who have a driver's license, for all applicants who successfully complete the requirements for a restricted motorcycle endorsement. Applicants for such license or endorsement shall furnish proof of their fitness to drive a motorcycle as the director shall in his or her discretion determine. Such proof shall include the applicant's passing a driver examination conducted on a motorcycle. The examination for a restricted motorcycle endorsement and the examination for a 3-wheeled motorcycle restriction shall be separate and distinct examinations emphasizing the skills and maneuvers necessary to operate safely the specific type of motorcycle for which the restriction is issued. The director may waive the requirement for such a driving examination upon receipt of adequate evidence of experience in driving a motorcycle by an applicant under such rules as the director may deem necessary, or proof that the applicant has successfully completed a state-approved motorcycle rider education course. No person may take the motorcycle driver examination more than twice; any person who fails to pass the examination twice shall be required to successfully complete the motorcycle rider education program under RSA 263:34-b. No person shall drive a motorcycle on a way of this state, unless such person is duly licensed to drive a motorcycle by a motorcycle license, restricted motorcycle license, or endorsement issued under this section, or holds a permit under RSA 263:32. No person shall knowingly authorize or allow the driving of a motorcycle owned by him or her or in his or her charge on a way of this state by any person who does not hold a motorcycle license, restricted motorcycle license, or endorsement or motorcycle learner's permit.
