# Greater London Authority Act 1999, Paragraph 3


(1) If a person travelling on a ticket bus service who has had a reasonable opportunity to obtain a fare ticket for a journey on that service fails to produce a fare ticket or a general travel authority on being required to do so by an authorised person, he shall be liable to pay a penalty fare if required to do so by an authorised person.
(2) If a person travels on a non-ticket bus service without paying the fare properly payable for a journey on that service and, while so travelling, fails to produce a general travel authority on being required to do so by an authorised person, he shall be liable to pay a penalty fare if required to do so by an authorised person.
(3) In this paragraph a “ticket bus service” means a local service on which fare tickets are issued in return for fares paid by persons travelling on that service, and a “non-ticket bus service” means a local service on which fare tickets are not so issued.
