What class of license is required to be allowed to drive any school purposes bus in Ontario?

Answer: B — B

A A class license is not required to drive a school purposes bus in Ontario. C: A class C license only allows the driver to operate a regular bus but not a school purposes bus. D: A class D license only allows the driver to operate a school purposes bus with a seating capacity of 24 or fewer passengers. In this case, the question is asking for the license required to operate any school purposes bus, not just one with a certain seating capacity. B: The correct answer is B because a class B license is specifically for operating a school purposes bus with a seating capacity of 24 or more passengers. This is the only license that covers all types of school purposes buses in Ontario.
