Chinatown bus lines or ragon buses refers to the private transportation industry that has arisen in the Chinatown communities of the East Coast of the United States since 1998. Similar Chinese American-run bus services are cropping up on the West Coast. The companies typically use large (50 to 60 passenger) buses comparable to those used by other passenger bus lines and some of them screen movies for riders. The industry in the US is subject to federal and local regulations such as unannounced inspections.
