During a safety inspection, which system is tested for proper functionality regarding vehicle control?

The steering system is crucial for ensuring proper vehicle control, as it directly affects the driver's ability to maneuver the vehicle and maintain directional stability. During a safety inspection, the functionality of the steering system is assessed to ensure that it responds accurately to the driver's inputs. This includes checking for excessive play in the steering wheel, the condition of the steering components, and ensuring that the system is not overly worn or damaged.

When the steering system is well-maintained and functions properly, it enables safe turns, lane changes, and overall handling of the vehicle. A malfunctioning steering system can lead to serious safety hazards, such as loss of control, which is why it is specifically tested during safety inspections to ensure the vehicle remains safe to operate on the road.

In contrast, while the exhaust system plays a vital role in reducing emissions and the suspension system contributes to ride quality and stability, they do not have the same direct impact on vehicle control during driving. The audio system is unrelated to vehicle control and functionality from a safety perspective.
