What are the three collisions involved in every crash?

In any vehicle crash scenario, the three collisions that occur are categorized as vehicle collision, human collision, and internal organs collision.

The vehicle collision refers to the initial impact where one or more vehicles come into contact. This includes the forces that are exerted on the vehicles involved. The human collision occurs when the body of the occupant inside the vehicle strikes the interior or other objects due to the momentum generated by the initial impact. This can lead to injuries as the human body undergoes rapid deceleration. Lastly, the internal organs collision describes the impact forces experienced by the internal organs of the body against the skeletal structure. This emphasizes the understanding of how different parts of the body are affected during a crash, primarily due to the difference in mass and the physical forces at play.

Understanding these three types of collisions helps law enforcement, emergency responders, and accident investigators analyze the mechanics of a crash, assess injuries, and develop strategies to prevent similar incidents in the future.
