Any proprietor, or agent of a proprietor, or any driver of a licensed stage-carriage, who, knowingly permits such carriage to be drawn by a less number of horses, or who knowingly permits a larger number of passengers, or a greater weight of luggage, to be carried by such stage-carriage than shall be provided by the license, shall be liable on a first conviction to a fine not exceeding one hundred rupees, and on any subsequent conviction, to a fine which may extend to five hundred rupees.
     In every case where such stage-carriage shall be proved to have been drawn by a less number of horses, or to have carried a larger number of passengers or a greater weight of luggage, than shall be provided by the license, the proprietor of such carriage shall be held to have knowingly permitted such offence, unless he shall prove that the offence was not committed with his connivance, and that he had taken every reasonable precaution and had made reasonable provision to prevent the commission of the offence.
