During what scenario does PTSD commonly establish itself according to crash data?

Post-Traumatic Stress Disorder (PTSD) is commonly recognized as a mental health condition that can develop after experiencing or witnessing a traumatic event. In the context of traffic incidents, PTSD is more likely to establish itself after severe accidents. These types of accidents often involve significant physical harm, considerable emotional distress, and a greater likelihood of life-threatening circumstances, all of which can deeply impact an individual’s mental state.

Severe accidents tend to create a heightened sense of danger and fear, which can lead to lasting psychological effects such as anxiety, flashbacks, and intrusive thoughts associated with the traumatic event. While minor accidents or those without injuries might still cause stress or anxiety, they generally do not produce the same level of trauma necessary for the development of PTSD. Therefore, the intensity and nature of severe accidents make them the most likely scenario for PTSD to manifest, aligning with the evidence from crash data.
