How many people can you fit in a standard tractor trailer?

The capacity of a standard tractor trailer for carrying people is typically not designed for passenger transport, as it is primarily intended for cargo. However, if one were to fit people inside, it could potentially accommodate around 20-30 individuals, depending on the size of the trailer and the seating arrangements. Safety regulations and legal restrictions would also limit the number of passengers. It's important to note that transporting people in a tractor trailer is generally unsafe and not recommended.
