Any drive shaft extending lengthwise under the floor of the passenger compartment of a sedan-type autobus, except sedan-type autobuses having a seating capacity of five or less passengers, shall be protected by means of at least one guard or bracket at that end of the drive shaft which is provided with a sliding connection (spline or other such device) to prevent the whipping of the shaft in the event of failure thereof or of any of its component parts. A shaft contained within a torque tube shall not require any such device.
