Question to the Department for Transport:

To ask the Secretary of State for Transport, how many drivers and riders killed in road collisions had (a) toxicology results available, (b) toxicology results available for alcohol and (c) toxicology results available for drugs, in each of the last ten years; and what proportion of all deceased drivers and riders those figures represented in each year.

Statistics on drivers killed in road collisions with toxicology results is based on data reported to police using the STATS19 system and data that is received by the Department from coroners and procurators’ fiscal. The latest year for which coroner and procurators’ fiscal data is available is 2024.

The number of a) drivers or riders killed in road collisions, in Great Britain, where toxicology results were available for alcohol or drugs and;

the proportion of all deceased drivers or riders this represents, for each of the last 10 years is provided in the table below.

Note: Pedal cycle riders and horse riders have been filtered out of the data. This is because the current prescribed alcohol and drug limits apply only to drivers of motor vehicles. This only includes drivers or riders aged 16 or above.

Information on (b) the number of killed drivers and riders with toxicology available for alcohol and;

c) the number with toxicology available for drugs area available on GOV.uk in tables 1 and 2 of the report on “Drugs in reported road fatalities in Great Britain”: https://www.gov.uk/government/statistics/developing-drug-driving-statistics
