DRINKING DRIVERS IN CANADA. A NATIONAL ROADSIDE SURVEY OF THE BLOOD ALCOHOL CONCENTRATIONS IN NIGHTTIME CANADIAN DRIVERS

In accordance with an internationally accepted methodology, a National Roadside Survey of the blood alcohol concentrations (BAC) of the nighttime driving population was undertaken in 1974. The objective of this survey was to assess the extent and nature of driving after drinking in Canada. The survey was conducted on each Wednesday, Thursday, Friday and Saturady of a 12 week period. In the course of this survey, over 9,700 drivers were stopped between the hours of 10 p.m. and 3 a.m. at 585 randomly selected sites. Each driver was asked to voluntarily provide a breath sample and information on drinking and driving habits, trip length and basic demographic characteristics. This report describes the survey methodology, the sampling and analysis procedures, and the relationships between BAC and demographic, driving and drinking variables are presented. This report examines the extent and nature of the drinking-driving problem in Canada and the further use of these data in monitoring the effectiveness of future countermeasure activities. /Author/
