A chauffeur is one who rives an automobile as a job. While the term may refer to anybody who drives for a living, it usually implies a driver of a luxury sedan, especially a limousine; those who drive non-luxury cars are simply called "drivers" (as in bus drivers). In some countries, particularly developing nations where a ready supply of labor ensures that even the middle classes can afford domestic staff and among the wealthy who avoid affectation, the chauffeur may simply be called the "driver."
