"Clunk Click Every Trip" is the slogan of a series of British public information films, commencing in January 1971 and starring Jimmy Savile. The BBC adapted Savile's slogan for the title of his Saturday night variety show beginning in 1973. The slogan was introduced during the previous campaign, fronted by Shaw Taylor and featuring the slogan "Your Seatbelt Is Their Security". However, it was the onomatopoeia used by Taylor to describe the act of closing the door and fastening a seatbelt that proved the most memorable aspect of that campaign, and so it was upgraded to act as the slogan when the films moved into colour.
