A vehicle for hire is a type of transportation service that allows people to pay for rides in a car. The most common types of vehicles for hire are taxis, cabs, and hackneys. Taxis are typically four-door cars with a yellow or green light on the roof that indicate they are available for hire. Cabs are usually three-door cars that are also available for hire. Hackneys are seven-door cars that are used for public transportation. All of these vehicles for hire provide a convenient way for people to get around without having to own their own car.
