Under rules and regulations the commissioner adopts, the commissioner may, by written order, suspend or modify the requirements of filing as to any kind of insurance, or subdivision or combination of insurance, or as to classes of risks, the rates for which cannot practically be filed before they are used. Those orders, rules, and regulations shall be made known to insurers and rating organizations affected by them. The commissioner may make an examination as the commissioner may deem advisable to ascertain whether any rates affected by an order meet the standards set forth in § 27-9-4(a)(4).
