CLARIFICATION OF REQUEST
I would just like to add a clarification to my FOI sent yesterday regarding breath tests.
Please take this to mean only roadside breath tests.
I would also like the local authority level breakdown, but if this would cause you to breach the cost limit to work out, please then disregard it and provide the force-wide data instead.
1. Every instance of breath tests for drivers and riders, by date, time, location by local authority and outcome for the calendar years 2012, 2013 and 2014.
It should therefore be possible to work out how many people were breathalysed each day of the year, at what times, the local authority in which it took place and the number of micrograms per 100ml of breath of each test.
For the outcomes, please also state whether the person was under or over the legal limit.
Please find attached our response.
Please note that these data should be interpreted with caution. Comparing numbers of crimes can be misleading, the number of incidents/crimes recorded in an area over a period of time can be influenced by a number of factors. Consequently statistics on incidents/crimes for one period may not necessarily be a good indicator of future incidents in that area.
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 a number of data sources used by forces for police purposes. The detail collected to respond specifically to your request is subject to the inaccuracies inherent in any large scale recording system. As a consequence, care should be taken to ensure data collection processes and their inevitable limitations are taken into account when interpreting those data.
The figures provided therefore are our best interpretation of relevance of data to your request, but you should be aware that the collation of figures for ad hoc requests may have limitations and this should be taken into account when those data are used.
