Question to the Department for Transport:

To ask Her Majesty's Government, further to the Written Answer by Lord Ahmad of Wimbledon on 21 December 2016 (HL4034), what progress has been made in collecting and publishing figures for the prosecution of incidents of drink driving which involve a casualty.

The Government are not yet in a position to publish any robust data in this area. Although preliminary work to develop suitable methodologies has taken place, it has not yet been possible to develop these into a data set that can be generated in a regular or systematic way. Both departments will continue to keep this area under close review going forwards.
