The various school boards are authorized to cause a provision to be inserted in policies issued under Code Section 20-2-1090 insuring the members of the general public against personal injury or death or damage to property resulting from the negligent operation of the school buses. Nothing, however, in this part shall be construed as imposing legal liability upon such boards on account of such accidents. Wherever an insurance company issues a policy containing such a provision, the company shall be estopped to deny its liability thereunder on account of the nonliability of the school board.
