Traffic Accident Response: Duties, First Aid, and Secondary Crashes
What this domain tests
Accident-response questions test the legal duties after a collision and the practical steps that prevent a second crash. Korean law requires stopping, helping, and reporting.
Immediate actions
Stop immediately, switch on hazard lights, and set the parking brake. If anyone is injured, call 119 and give first aid within your ability; call 112 for police. Move the vehicle only if it is safe and does not destroy evidence. On an expressway, place a warning triangle about 100 m behind the vehicle and move people behind the barrier.
First aid
Check consciousness and breathing. If unresponsive and not breathing normally, start chest compressions at 30 compressions to 2 breaths and use an AED if available. Control severe bleeding with direct pressure. Do not move a suspected spinal injury unless there is immediate danger, and do not give an injured person food or water.
Secondary crashes
Most expressway deaths involve people standing behind or beside the car. Face oncoming traffic, wear a reflective vest if available, and stand on the shoulder or behind the guardrail.
Worked example
Your car stalls in the fast lane of an expressway. You cannot push it to the shoulder. Correct sequence: hazards on, triangle at roughly 100 m, everyone out and behind the barrier, then call 112/119 and your insurer. Standing behind the boot to inspect the engine is the classic fatal error.
Traps that cost marks
Leaving the scene to call later, moving an injured rider, or placing the triangle just a few metres behind the car.
