He is a taxi driver.

Please drive safely, driver.
Commonly used to refer to professional drivers of vehicles such as cars, buses, and trucks.
When speaking to a driver professionally, use 運転手様 (unten-shu-sama) for added politeness.
Composed of 運転 (unten, 'driving') and 手 (shu, 'person'), literally meaning 'one who drives'.
In formal contexts, it is polite to address someone as 運転手 rather than just ドライバー.
