The city or town council after the drawing of warrants against the accident fund shall estimate the amount necessary to pay the warrants with accrued interest thereon, and shall levy a tax sufficient to pay that amount not exceeding seventy-five cents per thousand dollars of assessed value. If a single levy of seventy-five cents per thousand dollars of assessed value is not sufficient, an annual levy of seventy-five cents per thousand dollars of assessed value shall be made until the warrants and interest are fully paid.
