What are the three phases of a crash?

• A. Pre-crash, Crash, Post-crash
• B. Pre-Impact, Impact, Post-Impact
• C. Preparation, Impact, Aftermath
• D. Pre-Event, Event, Post-Event

Answer: (A)

Crash dynamics unfold in three phases: pre-crash, crash, and post-crash. The pre-crash phase covers the moment a hazard is detected up until contact—it includes how a driver perceives danger, reaction time, braking or steering decisions, speed, road conditions, and whether safety devices like seat belts are used. The crash phase is the actual moment of impact, when forces act on the vehicle and occupants, there is intrusion, and occupant motion and restraint performance determine how severe injuries can be. The post-crash phase starts with the crash and continues through emergency response, scene safety, first aid, patient assessment, and securing the area for further investigation and care. This breakdown helps analyze how a collision unfolds and informs prevention, investigation, and response strategies.
