The capacity of a cab depends entirely on the vehicle type and local regulations. A standard sedan taxi, like those seen in New York or London, typically accommodates up to 4 passengers: three in the rear and one in the front passenger seat. However, for larger groups in 2026, many fleets offer "minivan" or "SUV" cabs that can hold 5 to 7 passengers. In the UK, the iconic Black Cab is specifically designed to carry 5 or 6 passengers in the rear compartment alone. It is important to note that the driver is never counted in these passenger limits. For specialized commercial vans, a "single cab" usually holds 2-3 people, while a "double cab" can transport a crew of 5-7. Always check your local ride-hailing app or taxi dispatcher, as exceeding the legal passenger limit is a safety violation that can result in heavy fines for the driver and a refusal of service for your group.
