What does 'alignment' refer to in an inspection?

Alignment refers specifically to the adjustment of the wheels so that they meet the manufacturer specifications. Proper wheel alignment ensures that all wheels are pointed in the right direction and maintain the correct angle in relation to the vehicle's body and each other. This adjustment is essential for optimal handling, tire wear, and overall safety of the vehicle. When the wheels are properly aligned, it provides stability and improves the vehicle's performance on the road.

The other options do not accurately define what alignment pertains to. The condition of the engine relates to mechanical performance, the positioning of mirrors relates to visibility for the driver, and tire balance involves the even distribution of weight around the tire, which is distinct from alignment. Each of these elements is important for vehicle function but does not pertain to the process of aligning the wheels as specified by manufacturer guidelines.
