Question to the Ministry of Justice:

To ask the Secretary of State for Justice, how many drivers were convicted for (a) killing and (b) seriously injuring other road users whilst under the influence of (i) alcohol and (ii) illegal drugs in each year since 2010.

Information about drivers who have been arrested for being under the influence of drugs or alcohol and later convicted for causing death or serious injury, and information about whether an offender convicted for causing death or serious injury was under the influence of drink or drugs at the time of a driving offence is not held centrally and can only be obtained at disproportionate cost.

Data on the number of offenders convicted for drink or drug driving offences, and the specific offence of ‘causing death by careless driving under influence of drink or drugs’ is available in the motoring data tool in the annual criminal justice statistics publication, which can be found at https://www.gov.uk/government/statistics/criminal-justice-system-statistics-quarterly-december-2016
