Can I ride with someone else if I'm driving a moped?
No unfortunately the only passenger who can ride with you on the moped is your supervising driver.
What are the rules for driving with someone who is supervising me?
You may not drive unless accompanied by a supervising driver age 21 or older who has a valid license to operate the vehicle you are driving. So only a person with a motorcycle license may supervise a person learning to drive a motorcycle
