Chauffeur driven car businesses provide pre-booked journeys in a car driven by a professional driver. Customers may use the service for airport and railway station transfers, business travel, meetings, weddings, private events, sightseeing or journeys where they prefer not to drive. Vehicles commonly include saloons, executive cars and larger vehicles for groups or extra luggage, depending on the service offered. Bookings can be arranged for a single journey, a return transfer or a period of time, such as a day of meetings or an event. Services may include collection at an agreed place and time, help with luggage and waiting between stops. The vehicle and journey are usually selected to suit the number of passengers, luggage and occasion. In the UK, private hire journeys generally need to be booked in advance, and relevant drivers, vehicles and operators must be licensed by the local authority.
