A chauffeur is a person who drives a vehicle (car) as their job. The word can be used for anybody who drives as their job. Usually, it implies a driver of an elegant passenger vehicle (for example, a horse-drawn carriage, luxury sedan, motor coach, or especially a limousine). People who drive taxis, buses or non-passenger vehicles are generally referred to as "drivers" (as in bus drivers and truck drivers).
The main difference between a driver and a chauffeur is that a driver primarily transports passengers from one place to another, while a chauffeur typically provides a more personalized service, including assisting passengers with luggage, maintaining the vehicle and attending to their comfort during the journey.
