To understand the impact of drinking and driving laws on drinking and driving fatality rates, this study explored the different effects these laws have on areas with varying severity rates for drinking and driving. Unlike previous studies, this study employed quantile regression analysis. Empirical results showed that policies based on local conditions must be used to effectively reduce drinking and driving fatality rates; that is, different measures should be adopted to target the specific conditions in various regions. For areas with low fatality rates (low quantiles), people's habits and attitudes toward alcohol should be emphasized instead of transportation safety laws because "preemptive regulations" are more effective. For areas with high fatality rates (or high quantiles), "ex-post regulations" are more effective, and impact these areas approximately 0.01% to 0.05% more than they do areas with low fatality rates.
为了了解酒驾法律对酒驾致死率的影响，本研究探讨了这些法律对酒驾严重程度不同地区的不同影响。与以往的研究不同，本研究采用了分位数回归分析。实证结果表明，必须根据当地情况制定政策，才能有效地降低酒驾致死率；也就是说，应针对各地区的具体情况采取不同的措施。对于致死率低的地区（低分位数），应强调人们对酒精的习惯和态度，而不是交通安全法，因为“先发制人”的法规更有效。对于致死率高的地区（高分位数），“事后法规”更为有效，对这些地区的影响比致死率低的地区大约高出 0.01%至 0.05%。
