Safe riding requires knowledge and skill. Licensing tests are the best measurement of the skills necessary to operate safely in traffic. Assessing your own skills is not enough.
People often overestimate their own abilities.
In Missouri, you must have a Class M motorcycle license or permit, or a driver license with the M endorsement if you operate a motorcycle or motortricycle on public roadways. This permit will only be issued if you have successfully completed an approved motorcycle rider training course. You must also pass the Class F and Class M written, vision and road sign tests and have the written consent of your parent or legal guardian. If you are 16 years of age you may apply for a temporary motorcycle instruction permit, but you do not have to take the motorcycle rider training course. When you are ready, you may take the motorcycle skills test to be motorcycle qualified.
