The British colony of Hong Kong introduced its first double-decker buses in 1949 by Kowloon Motor Bus. By law, double-decker buses in Hong Kong are limited to a length of 12 metres (40 feet). Today, the majority of buses running in Hong Kong are double-decker buses. There are also double-deck trams; Hong Kong Tramways is the only tram company in the world that operates double-deck trams exclusively.
