本研究使用民國100年1月至108年12月各縣市警察機關取締酒駕、交通各項違規件數之資料進行實證分析,研究4次酒駕政策之行政罰(道路交通管理處罰條例第35條、道路交通安全規則第114條)與刑事罰(刑法第185-3)罰則的修定,是否使一地區之拒酒測率產生轉變。實證結果發現102年6月13日刑法185-3條與道路交通安全規則第114條之同步修訂,顯著的增加拒酒測率約4.7個百分點。而108年6月21日刑法第185-3之修訂(提高酒駕再犯之刑責)與108年7月1日道路交通管理處罰條例第35條(提高拒酒測罰鍰至18萬)之修訂,成功降低拒酒測率約3.3個百分點。;This research examines the effects of the statutory changes of drunk driving administrative penalty(Article 35 of the Road Traffic Management and Penalty Act and Article 114 of Rules of Road Traffic Safety)and criminal penalty(Article 185-3 of the Criminal Code of the Republic of China)on the breath test refusal rates. From early 2011 to the end of 2019, the authorities in Taiwan increased the fine, extended the license suspension period and jail time, etc., for drunk drivers. We find that the amendments to Article 185-3 of the Criminal Code of the Republic of China and Article 114 of Rules of Road Traffic Safety in June 2013 significantly increased nearly 4.7% of the breath test refusal rates. Whereas the amendment to Article 185-3 of the Criminal Code of the Republic of China in June 2019 and the amendments to Article 35 of the Road Traffic Management and Penalty Act in July 2019 significantly reduced nearly 3.3% of the breath test refusal rates.
