To ask Her Majesty's Government what data are collected on the number of people killed and injured by road users who are breaking the law; and who collects those data.
The Department for Transport’s data on road accidents collected from police STATS19 returns reporting personal injury road collisions does not collect definitive information about whether any of the road users involved in a collision were breaking the law.
There is information in the STATS19 database to indicate, in the opinion of the police officer attending the scene, what contributory factors might have played a part in a particular road collision. However, this information is not recorded for all collisions and is based on the officer’s initial opinion assessment only before any legal action has taken place. In addition, information about breath test results at the scene is collected but there is no record of whether this led to a prosecution or conviction.
Data on prosecutions are collected by the Ministry of Justice.
