Fares often consist of many parts. In many taxicabs, a taximeter measures the fare based on the length of the trip and the amount of time the trip took. Drivers turn the taximeter on when passengers enter the cab and turn it off when they reach the final destination. Passengers generally add a tip or gratuity to the fare. The amount of the gratuity depends on the passengers' satisfaction with the quality and efficiency of the ride and courtesy of the driver.
Drivers issue receipts upon request from the passenger.
These logs help check the driver's activity and efficiency. Drivers also must fill out accident reports when necessary. Chauffeurs operate limousines, vans, and private cars for limousine companies, private businesses, government agencies, and wealthy individuals. Many chauffeurs transport customers in large vans between hotels and airports, bus, or train terminals. Others drive luxury automobiles, such as limousines, to business events, entertainment venues, and social events.
