What is the difference between structural and non-structural damage?

• A. Structural affects the frame or unibody
• B. Non-structural affects outer panels
• C. Structural affects interior
• D. Non-structural affects engine

Answer: (A)

Structural damage refers to damage to the vehicle’s frame or unibody—the main load‑bearing skeleton that holds the car together, carries crash energy, and keeps wheels, doors, and panels aligned. When the frame or unibody is bent, twisted, or otherwise compromised, it can change suspension geometry, steering feel, and overall safety, so repairs require precise measurement, possible frame straightening, and sometimes replacement of structural components. Non-structural damage involves parts that don’t carry loads for the vehicle’s structure, such as outer body panels, trim, glass, or interior components. These areas can be damaged in a collision without affecting the vehicle’s fundamental strength or alignment, so repairs are usually cosmetic or involve panel replacement and refinishing rather than structural work. So the statement that best describes structural damage is that it affects the frame or unibody—the backbone that determines the vehicle’s structural integrity. Interior damage and engine-related issues, while potentially serious, are not about the vehicle’s load-bearing structure, and outer panels are typically non-structural.
