Driving under the influence of alcohol en drugs : Results of the BIVV/IBSR three-yearly road safety attitude survey. The Belgian Institute for Road Safety (BIVV/IBSR) attitude survey is based on 1,540 interviews with drivers whose principal residence is in Belgium and who had driven a car or delivery van at least 1,500 km in the six months preceding the interview. The interviews were conducted verbally by the research agency Significant GfK in September and October 2012. In the attitude survey, respondents were asked to provide their opinion on a number of statements. Each attitude statement was examined to determine whether or not there was a correlation between the statement and certain driver characteristics (gender, age and region). The percentages were also calculated for the different categories of answers; where possible the figures were compared with those from previous attitude surveys conducted by the BIVV/IBSR and with results from other sources. It looked for the existence of significant differences depending on the respondent’s gender, age or region. The attitude survey 2012 comprised several sections. This report only includes the results for driving under the influence of alcohol, drugs and medication. (Author/publisher)
