Taxis are vehicles that provide transportation services to passengers for a fee. They can be hailed on the street, booked through a phone call, or requested via mobile apps. Taxis are typically marked with a distinctive sign and may have a meter to calculate fares based on distance and time. Taxis come in various types, including sedans, minivans, and electric vehicles. They are commonly used in urban areas where public transportation may be limited. Taxis offer a convenient way to travel, especially for those who need to reach a destination quickly or carry luggage.
