Knight Bus At Harry Potter Warner Bros Studios Royalty-Free Stock Image

For witches and wizards tired of using floo powder, for those who don't trust Apparation, for those who suffer from vertigo or for those who are terrified or sick of having to take a Portkey, the solution is the Knight Bus, a bus that appears whenever a witch or wizard, in urgent need of transportation, takes out her wand at the edge of a sidewalk. It is a purple, three-decker bus with seats during the day and beds at night.
