Road accidents and safety
This series presents statistics on road safety in Great Britain. Most of the statistics are based on accidents reported to the police (STATS19 system). These provide detailed statistics about the circumstances of personal injury road accidents, including the types of vehicles involved and the consequent casualties.
Other sources directly related to road safety are also used, including hospital admissions, death registrations, coroner’s reports, surveys, and statistics on breath tests and motoring offences from the Home Office and Ministry of Justice.

Notes and guidance
As noted above, statistics on road safety in Great Britain are mostly based on accidents reported to the police via the STATS19 system. Comparisons with death registration statistics show that very few, if any, road accident fatalities are not reported to the police. However, it has long been known that a considerable proportion of non-fatal casualties are not known to the police, as hospital, survey and compensation claims data all indicate a higher number of casualties than are reported.
The Department produces an annual ‘best estimate’ of the total number of road casualties in Great Britain each year, including those not reported to police. This is derived primarily from National Travel Survey (NTS) data. The latest such estimates, along with a description of how the have been derived and their limitations, are set out in an annual article published in the in Reported Road Casualties Great Britain: Annual report.
The STATS19 data are therefore not a complete record of all injury accidents and this should be borne in mind when using and analysing the data. However, they remain the most detailed, complete and reliable single source of information on road casualties covering the whole of Great Britain, in particular for monitoring trends over time.
