Drivers must be on duty at all times of the day and night, because most taxi companies offer services 24 hours a day. Early morning and late night shifts are common. Drivers work long hours during holidays, weekends, and other special events to support heavier demand for their services. Independent drivers, however, often set their own hours and schedules. Design improvements in newer cabs have reduced stress and increased the comfort and efficiency of drivers.
Many regulators require standard amenities such as air conditioning.
Modern taxicabs are also sometimes equipped with sophisticated tracking devices, fare meters, and dispatching equipment. In a matter of seconds, dispatchers can deliver directions, traffic advisories, weather reports, and other important communications to drivers anywhere in the transporting area. The satellite link-up also allows dispatchers to track vehicle location, fuel consumption, and engine performance. Drivers can easily communicate with dispatchers to discuss delivery schedules and courses of action should there be mechanical problems. Taxi drivers and chauffeurs meet many different types of people.
