A 3-year enpidemiologic study of fatal motor vehicle accidents was carried out by the Alberta Task Force on Highway Accidents. It was found that 11.1% of culpable drivers had been driving while impaired by alcohol on at least one occasion prior to the fatal accident, while only 3.3% of exonerated drivers had previous records. This significant difference led to a case-control study that demonstrated that the recidivist drivers (case group) differed significantly in a number of aspects from the innocent drivers (control group)--notably, age distribution, sex, whether drinking before the accident, blood alcohol concentration, ethnic distribution, class of accident and type of collision. Thus the recidivist driver is a greater threat to highway safety than the innocent driver and needs special attention by legislators and law enforcement agencies.
艾伯塔省公路事故特别工作组开展了一项为期3年的致命机动车事故流行病学研究。结果发现，11.1%应受指责的司机在致命事故发生前至少有一次在酒精影响下驾车，而在被免除责任的司机中，只有3.3%有前科。这一显著差异促使开展了一项病例对照研究，该研究表明，累犯司机（病例组）在多个方面与无辜司机（对照组）存在显著差异——尤其是年龄分布、性别、事故前是否饮酒、血液酒精浓度、种族分布、事故类别和碰撞类型。因此，累犯司机对公路安全的威胁比无辜司机更大，需要立法者和执法机构给予特别关注。
