Why is it important that the frame is straight during inspection?

The importance of having a straight frame during inspection is closely linked to the impact on vehicle performance and safety. A straight frame is crucial because it directly affects how weight and forces are distributed across the vehicle. If the frame is bent or misaligned, it can lead to uneven weight distribution, which may cause tires to wear unevenly. This uneven wear can significantly shorten the lifespan of the tires and compromise the vehicle's handling and stability.

Furthermore, when the frame is not straight, it can cause issues with the vehicle's suspension and alignment, leading to more serious mechanical problems over time. Ensuring the frame is straight is vital for maintaining even tire contact with the road, optimizing traction, and promoting safe operation of the vehicle. Thus, the straightness of the frame is essential for the overall performance, safety, and longevity of the vehicle.
