On mopeds and motorcycles, in addition to the driver, a passenger who is over 12 years of age and uses a protective helmet may travel, provided this is stated on the vehicle's licence or registration permit. Exceptionally, from the age of 7, passengers may travel on motorcycles or mopeds driven by their father, mother or guardian, or by adults authorised by them, provided they wear an approved helmet.
