AEMCA Practice Exam

What are the impacts during a motor vehicle collision?

1. Only the car is impacted.

2. There are three impacts involving the car, the person, and the internal organs.

3. Most impacts are minor and do not cause injuries.

4. Only the person inside the car experiences impact.

The correct answer is: There are three impacts involving the car, the person, and the internal organs.

The choice that indicates there are three impacts involving the car, the person, and the internal organs accurately reflects the dynamics of a motor vehicle collision. When a collision occurs, the first impact is between the vehicle and an external object, such as another vehicle or an immovable object. This is often referred to as the primary impact. The second impact involves the occupants of the vehicle. When the vehicle comes to a sudden stop, the human body continues to move due to inertia until it encounters another object, such as the steering wheel, dashboard, or seatbelt. This is known as the secondary impact and can result in injuries to the occupants. The third impact pertains to the internal organs, which can crash against the ribcage or other surrounding structures within the body. This impact can lead to serious injuries, such as organ lacerations or internal bleeding, and is crucial to understanding the full extent of potential harm during a collision. This comprehensive view emphasizes the multi-faceted nature of collisions and the various levels of impact that can occur, leading to a range of possible injuries. Other answers do not encompass the complete picture of impacts during a motor vehicle collision, making this choice the most accurate and informative.
