What must inspectors check for in the steering system during a vehicle inspection?

Inspectors must focus on excessive play, wear, and proper operation of components in the steering system during a vehicle inspection because these factors directly impact vehicle safety and control. Excessive play in the steering can lead to a lack of responsiveness, making it difficult for the driver to steer effectively, especially in emergency situations. Wear on components such as the steering gear, linkages, and joints can also compromise the integrity of the steering system, potentially leading to failure during operation.

Proper operation of all steering system components is critical to ensure that the vehicle behaves predictably when the driver turns the steering wheel. Inspectors assess these elements to help identify any maintenance issues early on, which could prevent accidents and enhance the vehicle's overall reliability.

The other options are important aspects of vehicle inspections but focus on different systems or components. For instance, checking fluid levels and leaks pertains to the hydraulic aspects of steering or other systems, while alignment angles and tire wear are more relevant to the suspension and tire health. Equipment safety ratings don’t directly assess the physical condition of the steering system itself, making it less relevant for this specific inspection focus.
