A taxi is a type of public transportation vehicle that provides passenger services for hire. It can be hailed on the street, booked through a mobile app, or called from a dispatch service. Taxis are typically equipped with a meter that calculates the fare based on the distance traveled or the time taken.

Taxis are commonly used for convenient and private transport, allowing passengers to choose their destination. They are driven by licensed drivers and are often recognizable by their distinctive colors or markings, such as the brightly colored taxis in Bangkok or the yellow cabs in New York City.
