In case of emergency, the driver should also know the location of fire and police stations and hospitals. Upon reaching the destination, drivers determine the fare and announce it to the rider. 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.
