Question to the Department for Transport:

To ask the Secretary of State for Transport, what assessment he has made of the reasons why the number of deaths caused by drink-driving has increased each year since 2010.

The estimated number of people killed in accidents where at least one driver was over the alcohol limit has remained at 240 each year since 2010. The exceptions were 2012, for which the estimate is 230, and the provisional results for 2015, for which the estimate is 220. Once uncertainty is taken into account the figure should be regarded as being unchanged since 2010. During that time traffic has increased by 4.5%.
