Which type of impact involves the occupant striking the interior of the vehicle?

• A. Primary
• B. Tertiary
• C. Quarternary
• D. Secondary

Answer: (D)

When a crash happens, the vehicle stops fast but your body tends to keep moving forward because of inertia. That continued forward motion causes the occupant to strike the interior parts of the vehicle—dash, steering wheel, windshield, or door panels. This contact with the car’s interior is the secondary impact. The first impact is the vehicle hitting something externally, and the other terms refer to different injury mechanisms (such as internal organ movement or later contacts) rather than the occupant’s direct contact with interior surfaces. Understanding this helps explain why restraints like seat belts and airbags are so important—they limit that secondary impact by keeping the body part from slamming into hard interior surfaces.
