A chauffeured auto is a vehicle that is driven by a professional driver, often referred to as a limo. The term 'limo' is an abbreviation of the word 'LIMOUSINE, ' which is a luxury vehicle typically used for special occasions such as weddings, proms, and other events. Chauffeured autos are typically more expensive than regular cars, but they offer a higher level of comfort and convenience. They are also often equipped with amenities such as TVs, bars, and sound systems.
