A chauffeur is one who drives 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, the chauffeur is simply called the "driver."
A Chauffeur is a domestic professional who serves as a personal transporter to his/her principal in the course of all daily activities and events. A Chauffeur handles all care and conditioning of each vehicle. A Chauffeur is usually a confidant of his/her principal, and as such, discretion is a mandatory prerequisite for employment.
