Red Dwarf: Infinity Welcomes Careful Drivers is a best-selling science fiction comedy novel by Grant Naylor, the collective name for Rob Grant and Doug Naylor, co-creators and writers of the Red Dwarf television series, on which the novel is based. First published in 1989, the novel presents the plotline of the TV series as a cohesive linear narrative, providing expanded backstory of the Red Dwarf world and more fully developing each of the characters, particularly Dave Lister and Arnold Rimmer. The book incorporates elements and scenes from the first and second-season episodes The End, Future Echoes, Kryten, Me² and Better Than Life. In 1990, the book was followed by a sequel, Better Than Life.

Arnold Judas Rimmer is a fictional character in the science fiction sitcom Red Dwarf, played by Chris Barrie. Rimmer is characterised as a second-class technician and de facto leader of the mining ship Red Dwarf. Portrayed as snobbish, pedantic, and self-centred, Rimmer is unpopular with his crewmates and is often the target of insults and general ridicule.
