1 Following a comparison between the number of positive breath tests reported by each police force in 2006, and the number of court proceedings for drink/driving related offences, it became clear that there was under-reporting in a number of forces. As a result Essex, Humberside, Lancashire, Norfolk, Northumbria, Staffordshire, Dyfed-Powys, Gwent and South Wales court proceedings figures have been substituted for the positive breath test figures. Similar adjustments were also made to various forces data between 1998 and 2005.
