Question to the Department for Transport:

To ask the Secretary of State for Transport, whether his Department has conducted an assessment of the (a) reasons for the change in the number of drink-driving convictions between 2004 and 2014 and (b) the implications of that change for the Government's policy on drink-driving.

We have made no assessment of changes in drink-driving convictions; however, drink drive casualties went down in the period 2004 to 2014 and drink drive fatalities are at their lowest ever level; the proportion of people who tested positively for alcohol following a reported road traffic accident has fallen from 4% in 2004 to 3% in 2014; and the overall proportion of drivers who tested positively on a roadside screening test fell from 18% in 2004 to 11% in 2014. We continue to promote our THINK! Campaign and we have no plans for lowering the drink drive limit.
