which body parts are hit first during the initial blow from a collision?

During the initial blow from a collision, the first body parts hit are typically the soft tissues, including the collarbone and areas where the seatbelt is positioned. The collarbone is often one of the first injured due to the seatbelt pressing against it. Immediately after impact, the head and body keep moving at the same speed until the head collides with something like the airbag, dashboard, or windshield. Soft tissues bear the initial impact before harder structures like bones or organs get involved in subsequent injury phases. Additionally, ribs and pelvic bones may be affected depending on the severity and nature of the collision, with arms and legs also susceptible to injury from contact with interior surfaces of the vehicle.
