About this data
These files provide detailed road safety data about the
circumstances of personal injury road collisions in Great Britain
from 1979, the types of vehicles involved and the consequential
casualties. The statistics relate only to personal injury
collisions on public roads that are reported to the police, and
subsequently recorded, using the STATS19 collision reporting
form. This data contains all the non-sensitive fields that
can be made public. Sensitive data fields, for example
contributory factors data, can be requested by completing
the sensitive data
form and contacting the road safety statistics team
at roadacc.stats@dft.gov.uk.
All the data variables are coded rather than containing textual
strings. The lookup tables are available in the guidance and documentation
section.
The introduction of injury based reporting of casualty severity
for some police forces appears to have led to a change in the
reported severity of road casualties. As a result
the severity adjustment
methodology has been used to adjust the reported
severity of historic collisions to account for this change. In
previous years the severity adjustment figures have been provided
as separate files that users have to join to the main data, with
the publication of the 2024 statistics these adjustment figures
are now provided as part of the main data tables.
