The fourth series of On the Buses originally aired between 27 November 1970 and 21 February 1971, beginning with "Nowhere to Go". The series was produced and directed by Stuart Allen and designed by Alan Hunter-Craig. All the episodes in this series were written by Ronald Chesney and Ronald Wolfe.[1][2]
Due to the ITV Colour Strike, most of the episodes from the second half of series four plus the Christmas Special 1970 were shown in black-and-white.
