Fare carriers are transportation services that charge a fee for transporting passengers from one place to another. The two most common fare carriers are CABS (4 letters) and TAXIS (5 letters). CABS are usually smaller vehicles, such as cars or vans, that can be hailed on the street or called for a pick-up. TAXIS are similar to CABS but are typically larger vehicles, such as minibuses or limousines, that must be booked in advance. Both CABS and TAXIS provide a convenient way for people to get around without having to drive themselves.
