As an operator, you should prepare a passenger to ride by instructing them to do each of the following, except:

Before beginning a ride, you should ask your passenger to mount the motorcycle only after the engine has been started. They should sit as far forward as they can without crowding you and hold onto the motorcycle's passenger handholds or onto your waist, hips, or belt. They should keep their legs away from the muffler, chains, and other moving parts.
