A four-door vehicle was involved in a frontal impact. Adjust the _____panel assembly first

• A. Rear Door
• B. Front Door
• C. Trunk
• D. Roof

Answer: (A)

In this situation, the sequence for restoring body alignment after a frontal impact centers on establishing a solid reference on the side of the car before touching the damaged area. The rear door panel assembly is chosen first because it tends to be less distorted by a frontal collision and can serve as a stable, reproducible baseline for the body line and gaps. By getting the rear door to fit correctly and line up with the surrounding panels (such as the quarter panel and rocker area), you create a reliable reference from which to adjust the adjacent front door and other panels. This helps ensure that the overall side-to-side alignment remains consistent across the vehicle.

Starting with the front door or other panels can complicate things because those areas are more likely to have direct impact distortion, making it harder to establish accurate gaps and lines. The trunk and roof aren’t the primary reference points for aligning the side of the vehicle after a frontal impact, so they aren’t the first focus in this context.
