強制汽車責任保險自1998年1月1日實施至今，立法精神及施行成效深受社會大眾肯定。隨著社會安全制度的持續發展，持續進行全盤檢討，並於2005年2月5日公布新修正強制汽車責任保險法，3月1日正式實施。 由於強制汽車責任保險風險分類直接反應於費率計算，資訊不對稱容易形成道德風險，被保險人與保險人產生顯著資訊落差，保險人無法合理歸類被保險人風險特性，保費計算上易受外界雜訊所影響，產生嚴重道德風險。為降低資訊不對稱的成本增加，保險輔助人成為被保險人與保險人間資訊傳遞的重要中介機構。如何健全保險輔助機構的執業規範及分工定位，以降低資訊不對稱所造成之負面影響，成為強制汽車責任保險的重要監理議題。 本研究主要檢視現行強制汽車責任保險制度，如何有效規範保險輔助人，強化保險作業與交通監理作業降低資訊不對稱成本，討論具體措施諸如設立保費查詢中心、確保理賠損失資料之正確性、各項財務資訊揭露透明度與落實保險人之差異化管理政策，並歸納具體建議如下： 一、 建立強制汽車責任保險專屬網站，強化資訊揭露； 二、 交通監理作業投保查詢應整合保險查詢，減少代理成本； 三、 落實保險人內部稽核，建立承保及理賠標準流程； 四、 建立保險輔助人評等制度，維護市場公平競爭； 五、 車種分類及費率精算宜朝簡化為原則，避免道德風險。 / The Compulsory Automobile Liability Insurance Law has been enforced since January 1, 1998, the spirit of the law and the goodwill lay behind it were highly praised by the general public.
