In a car crash, there are actually three different collisions that occur, even though we usually only think about the vehicle hitting something. Understanding these three stages helps explain how injuries happen, even in accidents that don’t seem severe.
Vehicle collision
The first collision happens when the vehicle crashes into an object like another car, a tree, or a guardrail. This is what most people think of when they imagine a crash. The vehicle suddenly slows down or stops, but everything inside the vehicle, including the people, keeps moving at the same speed as before.
Human collision
After the vehicle hits an object, the second collision happens. This involves the people inside the vehicle. Their bodies continue moving until they hit something, such as the steering wheel, dashboard, windshield, or even the seatbelt. Seatbelts and airbags help prevent serious injuries by slowing down this second collision and reducing the force on the body.
Internal collision
The third collision occurs inside the body. Even after the human collision, the organs inside a person’s body keep moving. This movement can cause them to crash into bones or other organs, leading to internal injuries. The brain hitting the inside of the skull, or the heart and lungs striking the ribs, are examples of this internal collision.
An unseen danger
Recognizing the complexity of collisions during a crash underscores the importance of proactive safety measures. By taking steps to minimize harm, drivers can better protect themselves and others on the road. The layers of impact in an accident are a reminder that even seemingly minor crashes can result in significant consequences for the human body.
