How many passengers can a Class B vehicle transport?

A Class B vehicle, as defined by transportation regulations, is typically designed to transport passengers in larger quantities than smaller vehicle classifications. Specifically, a Class B vehicle can carry 24 passengers or more, which is why this choice is correct.

In practical terms, these vehicles are often used for commercial passenger transport, such as buses used in public transit systems, which require a specific licensing to operate. The classification ensures that the vehicles meet safety and operational standards necessary for handling such capacities.

The other options, while they indicate various capacities, do not align with the regulatory definition for Class B vehicles. Choices indicating fewer than 24 passengers would pertain to different classes of vehicles, such as Class C.
