Which vehicle primarily designed for carrying people could be constructed on a truck chassis?

A multi-purpose passenger vehicle is designed to carry people and can indeed be constructed on a truck chassis. This type of vehicle is versatile and includes SUVs and crossover vehicles that often share a platform with trucks, which allows for increased durability and capacity for passenger transport. These vehicles are typically designed to combine passenger comfort with utility, making them suitable for both personal and commercial use.

In contrast, options like a low-speed vehicle and a motorcycle do not fit the criteria as closely. A low-speed vehicle is typically limited in speed and designed for short distances, often lacking the capacity or structure to be built on a truck chassis. A motorcycle, while capable of carrying passengers, does not utilize a truck chassis in its design or construction. A limousine, on the other hand, is primarily focused on luxury transport and is generally built on a car chassis, although it may share some characteristics with a truck chassis; the term "multi-purpose passenger vehicle" more accurately encompasses the broader range of vehicles designed to transport people and can be built on a truck chassis.
