THE next time you get taken for a ride in a taxi, it should be good, clean fun. The territory's 15,000 taxis and 7,500 public light buses are the target of a clean-up campaign designed to raise public awareness as well as encouraging tidiness. Crown Motors, which supplies 90 per cent of Hongkong taxis and the majority of the public light buses, yesterday linked its annual cleanliness drive to the Urban Council's Keep Hongkong Clean crusade. Taxis will be checked by roving inspectors and awarded a badge if they make the grade. The names of their drivers will be entered into a lucky draw. Crown Motors general manager for sales and marketing, Mr William Tsui, said: ''It is extremely important to have clean taxis. Hongkong has a big tourist industry and one of the first impressions anyone gets is from a taxi.'' Mr Pao Ping-wing, chairman of the Urban Council's cleanliness campaign committee, welcomed the initiative.
