If (as you stated in Question 2785/2006) the Metropolitan Police don't hold figures on the numbers of breath tests it conducts, who provides the Home Office with the figures on total number of breath tests and the proportion that are positive or refused, which are published annually in "Motoring Offences and Breath Tests, England and Wales"? If the Metropolitan Police do, in fact, collect and hold this information, would you like to revisit your answers to questions 2784/2006 and 2785/2006?

Answer for Breath testing

Answered By: 
The Mayor

The Metropolitan Police don't record the total number of breath tests administered to drivers (i.e. all negative and positive tests). I am informed that whilst this used to happen, it was decided that the process was time consuming, imprecise and that it served no useful purpose in the reduction of drink drive related offences.The police do record the number of drivers arrested, for testing positive, for refusing a test or for being judged incapable of driving. These figures were provided in answer to question 2785/06. I am informed that the Home Office are sent figures including numbers for negative tests (so as to provide a total) but that these are only estimates based on historical data.
