Emergency advice

Managing a traffic accident:

  1. Park well away and turn on hazard lights.
  2. Protect the area and make vehicles safe.
  3. Call 999 and be alert for danger.
  4. Assess casualties using the primary survey.
  5. Treat casualties where you find them.
  6. Monitor their response. 

Traffic accidents can range between minor incidents such as a bicycle crash or much more serious incidents like a vehicle crash. It is crucial that the incident area is safe before you help any casualties. This is so that you, the casualties and other road users are protected.

Once you know the area is safe, quickly assess the casualties and prioritise treatment. Give first aid to anyone with life threatening injuries first before tending to other casualties.

Call 999 or 112 for emergency help and give as much detail about the incident as possible such as number and age of casualties and types of injury.

What to do

Make sure the incident area is safe for yourself and others

  1. Park safely and well away from the incident. Make sure you turn on your hazard lights and put on a high-vis jacket if you have one.

  2. Ask two car drivers to protect the incident area in each direction by parking well away and turning on their hazard lights. If you have warning triangles, the area can be protected using these as well. Bystanders can help you do this while you help the casualties.

  3. Make vehicles safe by switching off the ignition of all damaged and surrounding cars and if you can, disconnect the battery.

  4. Make vehicles stable. Apply the handbrake, put them in gear or put a block in front of the wheels if the vehicle is upright. If it is on it’s side, try to stop it rolling over further, but do not attempt to move it.

  5. Be alert for physical dangers such as traffic and make sure no one smokes near the incident.

  6. Call the emergency services to report damaged power lines, spilt fuel or vehicles carrying hazardous substances.

Assessing the casualties

  1. Call 999 or 112 straight away.

  2. Assess the casualties quickly by doing the primary survey and treat anyone with life threatening injuries first.

    • Assume that anyone involved in the accident may have neck or spinal injuries.
  3. Treat the casualties in the position you find them if possible and make sure you support their head and neck at all times.

  4. Make sure you search the surrounding area so that casualties who are not in the immediate incident area are found and treated. Ask other people to help you.

  5. If anyone is trapped inside or under a vehicle, the fire service will need to help them.

  6. Monitor the casualties and record their breathing, pulse and level of response.
