Question to the Department for Transport:

To ask the Secretary of State for Transport, whether her Department has made a recent assessment of the adequacy of data collected on road safety.

The Department’s road casualty statistics are based on data reported to the Department by police forces via the STATS19 system. Information on the strengths and weaknesses of this data are available in the background quality information which accompanies the published statistics on the gov.uk website.

While STATS19 is considered to be a valuable dataset in developing and monitoring road safety, with a wide range of users and uses, the Department is exploring a range of additional datasets to address some of its known limitations. A summary of recent and planned development work, published on 25 September 2025, is also available on gov.uk:
