Though journeys are defined as ‘short distances’ they may be of any overall length, as long as passengers can get off within 15 miles of the place at which they were picked up.
Er bod teithiau yn cael eu diffinio fel ‘pellter byr’ mae’n bosibl iddynt fod o unrhyw hyd cyffredinol, cyn belled ag y bo modd i deithwyr fynd oddi ar y bws o fewn 15 milltir i ble y cawsant eu codi.
