A correlational examination of 54 consecutive months of data from British Columbia on the relationships among the number of vehicles checked in police drinking-driving roadchecks, the number of driving while impaired (DWI) charges laid, the number and percent of alcohol-related casualty traffic accidents, and the extent of media coverage on drinking-driving (as measured by print media coverage), revealed that: the extent of media coverage, and not the extent of roadchecks or charging activity is probably the critical element in the reduction of drinking-driving accidents. The failure of the minimally publicized April-May 1984 British Columbia police roadcheck "blitz" to reduce either the number or proportion of alcohol-related casualty traffic accidents lent support to these correlational findings.
对来自不列颠哥伦比亚省连续54个月的数据进行的相关性研究，涉及警方酒驾路检中检查的车辆数量、提出的酒驾指控数量、与酒精相关的伤亡交通事故数量及百分比，以及媒体对酒驾的报道程度（以平面媒体报道衡量），结果显示：媒体报道程度，而非路检或指控活动的程度，可能是减少酒驾事故的关键因素。1984年4月至5月不列颠哥伦比亚省警方进行的宣传极少的路检“突击行动”，未能减少与酒精相关的伤亡交通事故的数量或比例，这为这些相关性研究结果提供了支持。
