A predominately Roman Catholic practice is to place a medal of Saint Christopher, the patron saint of truck drivers and travelers in general, inside the car. Usually, the driver will have this medal blessed by a priest. An ancient legend, mentioned by Erasmus in the "Praise of Folly", holds that those who see an image of Saint Christopher cannot die through misadventure during that day. Not surprisingly, images of Saint Christopher became popular automobile accessories. Through the presence of the medal, the driver is asking the Saint to pray on his or her behalf for a safe and uneventful journey.
