Key points – London 2022

  • Self-reported collisions are where the public, often the casualty, report the collision after the event, usually online. The police were unable to attend the collision. This may be because they were not notified or unable to attend in time, i.e. before those injured left for medical treatment.
  • Self-reported collisions are much less likely to result in a criminal prosecution or civil compensation, due to the lack of evidence collected at scene by police.
  • In London, cyclists are disproportionately involved in self-reported collisions:
      • Almost one in three seriously injured cyclists was self-reported, i.e. online, much more than other road user modes and twice the overall average.
      • Over half of slightly injured cyclists were reported on-line (52%), compared to 37% of all those reported seriously injured.
  • Given the impact self-reported collisions have on accessing justice, Action Vision Zero believes the police and Transport for London should know:
      • If casualties are choosing to self-report or if it is down to police being requested but being unable to attend in time.
    • Why cyclists are so disproportionately affected.
