Britain has one of the best records in the world for road casualties. However, hundreds still die on the roads every year. In 2010, the police recorded 1,850 deaths, 22,660 people seriously injured and 184,138 who received light injuries.

About the map: Using official data recorded by police in Great Britain between 1999 and 2010, we have plotted every road collision in which someone died. In all, 36,371 fatalities are marked on this interactive map. You will also find partial data for Northern Ireland, for 2004-2009.

How the data is gathered: Detailed information about each crash is recorded by the police at the scene. It is subsequently transferred onto a computer database. This is available to researchers from the Economic and Social Data Service.

Missing data: As with any large collection of data, there will be errors and omissions. The BBC apologises for any distress or offence that may be caused by the inclusion of these errors.
