First Aid, Emergency Response and Accident Procedures

What this domain tests

First aid, emergency response and accident procedure tests what you do in the first ten minutes after a crash - the part that decides whether someone lives.

At the scene

  1. Stop. Failing to stop after an injury crash is an offence.
  2. Make the scene safe: hazard lights, reflective vest, warning triangle well back (further on a fast road or a blind bend), engine off, no smoking near fuel.
  3. Call the emergency services - police 117, fire 118, ambulance 119 - and give location, number of casualties and hazards.
  4. Do not move an injured person unless there is fire, fuel or traffic danger. Do not remove a motorcyclist's helmet.
  5. Exchange names, licence, registration and insurance details; report the crash to police.

First aid basics

  • DRABC: Danger, Response, Airway, Breathing, Circulation.
  • Severe bleeding: direct pressure with a clean pad; do not pull out an embedded object.
  • Unconscious but breathing: keep the head aligned, monitor breathing, and use the recovery position only if you must leave the casualty.
  • Not breathing: CPR, 30 compressions to 2 breaths, about 100–120 compressions a minute.
  • Shock: lie the casualty down, keep warm, give nothing by mouth.
  • Burns: cool with clean water, do not burst blisters, do not peel clothing.

Worked example

A motorcycle has gone under your front bumper; the rider is on the road, breathing but unresponsive. Leave the helmet on, keep the head and neck still, check the airway, monitor breathing, keep him warm and shaded, and wait for the ambulance rather than lifting him into a passing car.

Traps

Giving water to a casualty; pulling off a helmet; moving vehicles in an injury crash to clear the road.
