Cabs, short for taxicabs, are vehicles for hire that transport passengers to their desired destinations. They are typically equipped with a meter that calculates the fare based on distance traveled and time taken. Cabs can be hailed on the street, booked via phone, or requested through mobile apps. Cabs come in various types, including traditional yellow cabs, ride-sharing services like Uber and Lyft, and luxury options. They provide a convenient mode of transportation in urban areas, helping people navigate busy streets without the need for personal vehicles.
