Road accidents and safety statistics

Statistics and data about reported accidents and casualties on public roads in Great Britain.

Road casualty annual statistics

Annual road casualty statistics are published twice each year. Main results are published in June for the first release of key statistics, and the annual report is released in September for detailed data and analyses. Most of the statistics are based on road accidents reported to the police (Stats19). These provide detailed statistics about personal injury road accidents, vehicles and casualties involved.

Guidance on current and previous annual road casualty statistics and main results is available.

Road safety data download tool: we are trialling a new tool for you to download bespoke breakdowns of our data.

Road casualty in-year estimates

In-year estimates are based on road accidents reported to the police (Stats19). They provide a provisional estimate of road accidents and casualties.

Guidance on current and previous quarterly road casualty estimates are available.

Drink drive estimates

Estimates for road accidents involving illegal alcohol levels are published twice a year. Provisional estimates are released in February and final estimates in August.

Guidance on current and previous final and provisional drink-drive estimates are available.

International comparisons of road safety data are available on these external websites:

Ad-hoc surveys and factsheets are published from time to time.

About the road safety statistics data and reports

Claims management companies may ‘cold call’ people saying that they have records that you were in an accident. They claim to have got your information from the national road accident database or a governmental body. This is not correct. No government agency or department holds names, addresses or telephone numbers of people who have been in road traffic accidents.

There is no national database of accidents with names, telephone numbers and addresses. Government departments do not hold any of this information, and even if they did, they would not supply it to anyone under any circumstances as citizen personal data would be protected under the Data Protection Act.

If you have been contacted in such a way, it is most likely to be as a result of cold calling or random number dialling. If you are able to get a contact name and number for the company you can report them to the Claims Management Regulator.

Statistics on road safety in Great Britain are mostly based on accidents reported to the police in the Stats19 collection. This system allows police forces to report all personal-injury accidents to the department. It is not used to collect any information about damage-only accidents. Information on Stats19 can be found in the report form and the guidance document used by the police when completing the form.

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 to the police.

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.

Other sources directly related to road safety are also used, including hospital admissions, death registrations, National Travel Survey, crime survey from England and Wales and data from the Home Office and Ministry of Justice.

Most of the statistics published are National Statistics. Road accident and safety statistics were assessed by the UK Statistics Authority and confirmed as National Statistics in July 2009 and again in 2013.

Road safety publications prior to 2010 can be found on the National Archives.
