|1 Following a comparison between the number of positive breath tests reported by each police force in 2004 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, Hertfordshire, Kent, Lancashire, South Yorkshire, 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 2003.Note:Every effort is made to ensure that the figures presented are accurate and complete. However, it is important to note that these data have been extracted from large administrative data systems generated by police forces. As a consequence, care should be taken to ensure data collection processes and their inevitable limitations are taken into account when those data are used.| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
