The document outlines the film classification system used by the British Board of Film Classification (BBFC). It describes the various ratings from U ("Universal") to R18 and what types of content each rating allows. A U rating is suitable for all ages but prohibits bad language, sexual content, or distressing scenes. PG introduces mild violence and discretion is left to parents. 12A allows some strong language or discreet sexual references. Higher ratings of 15 and 18 permit increasingly strong language, violence, sexual or abusive content, but R18 is limited to licensed venues due to explicit pornography.
