Q

a ptnt typically experiences 3 collisions in a car accident. these are:

A

collision of car against car/object/tree (greater damage to the car, greater damage to the patients)

collision of passenger(s) against the cars interior. worse if the patient is not restrained.

collision of the patients internal organs against the solid structures of the body. these injuries are not as apparent but can be the most life threatening.
