The owner of any school bus or provider of school transportation vehicle services transporting children to and from any private or public school, or the owner of any bus owned or used by a religious organization or a nonprofit organization used exclusively as a bus for the transportation of its members in connection with functions of the organization, shall submit to the authorities in the town or city or to the organization which pays for said transportation a list of names of the persons who are to drive the buses or school transportation vehicles used in such transportation. Such authority shall submit the list of names to the department requesting an investigation of each driver's criminal and motor vehicle record. If such driver is found to be qualified to bear the responsibility of such transportation, the division shall cause said driver to be examined under the rules adopted pursuant to RSA 265:58. No person shall drive a school bus or school transportation vehicle unless he has satisfactorily passed the special examination for said driving and received from the division a special school bus driver's certificate for a school bus or school transportation vehicle. The director may revoke such special school bus driver's certificate for good cause shown.
