The police generally make further investigations when a road collision involves fatal or serious injuries, aggressive or impatient driving, misuse of speed, although other circumstances are considered. Not all investigations result in a prosecution, a driver will only be prosecuted if they are found to have committed an offence.

There are many circumstances where there is insufficient evidence for a criminal prosecution, but a civil claim for a personal injury is still possible. A criminal prosecution and a civil claim are dealt with in different courts and different rules apply.

If the police attended the scene of a road collision, they should:

  • Ensure the scene of the accident is safe.
  • Ensure injured people receive appropriate medical treatment.
  • Determine how the accident occurred, and consider possible offences.
  • Direct traffic around the accident scene safely.
  • Record accident details.
  • Identify and obtain witness details.
  • Assist with the recovery of vehicles from the scene.

If the police do not attend the scene of a road collision, you should:

  • Ensure anyone injured receive help.
  • Ensure people and cars are not creating further hazards.
  • Make a record of how the accident occurred whilst it is still fresh in your mind.
  • Exchange details with other drivers involved in the road accident.
  • Obtain names and addresses of witnesses to the accident if possible.
  • Sketch the accident scene or take photographs.
