The nanny van (Chinese: 褓姆車) or school private light bus is a kind of school bus service in Hong Kong. At its peak of popularity during the 1980s, it had become a form of "illegal" public transportation. Subsequently, due to unauthorized use of the vans, the government banned them as a form of public transportation and required all existing nanny vans to register and operate on designated routes.
All nanny vans in service today are required by the government to have both the Chinese text "學校私家小巴" and the English text "SCHOOL PRIVATE LIGHT BUS" in capital letters painted on the sides of the vans. There were 1769 such buses registered with the Transport Department in 2014.[1]
