Self-reported drink and drug driving

This article presents data on self-reported drink and drug driving from the Crime Survey for England and Wales (CSEW)1. The CSEW has included questions asking people whether they have driven whilst over the legal alcohol limit, or under the influence of illegal drugs, since 2009. This article presents data from the 2009/10 and 2010/11 waves of the survey.
In both 2009/10 and 2010/11, an estimated 8 per cent of adult drivers who had consumed alcohol in the last year reported driving at least once or twice within the last 12 months whilst they thought they were over the legal alcohol limit. In 2010/11, an estimated 19 per cent of adult drivers who had taken illegal drugs in the last year reported driving at least once or twice within the last 12 months whilst they thought they were affected by or under the influence of illegal drugs. This was similar to 2009/10, where an estimated 17 per cent reported driving at least once or twice within the last 12 months whilst under the influence of illegal drugs.
