Samenvatting
The UK Road Traffic Act 1991 allowed certain Courts to offer drink/drive offenders the opportunity to attend a rehabilitation course. This paper examines reconviction rates over three years of more than 20,000 drink/drive offenders, 9000 of whom attended rehabilitation courses. The variation in the proportions of offenders completing rehabilitation training in 18 different Court areas provided an opportunity to model the effect of subject selection bias. Overall, taking selection bias into account, the drink/drive rehabilitation courses appear to have reduced reconviction rates by slightly more than 50 per cent.
