What is the maximum number of passengers a vehicle can transport, including the driver, to still be classified as a bus?

To be classified as a bus in Pennsylvania, a vehicle must have a seating capacity for more than 15 passengers, which includes the driver. Therefore, when considering the maximum number of passengers that can still classify a vehicle as a bus, it is important to recognize that a vehicle accommodating up to 16 passengers — one driver plus 15 additional passengers — falls within the definition used by transportation authorities.

If a vehicle seats 17 or more passengers, it would exceed the limit that categorizes it as a bus and may require different regulations or certifications. Thus, the total number for classification purposes is capped at 16 passengers, confirming that option B is the correct answer. Understanding this classification helps ensure compliance with safety and operational regulations for different vehicle types in Pennsylvania.
