Which is an example of a visual inspection during a pre-trip inspection?

Inspections conducted during a pre-trip check are essential for ensuring the safety and operational readiness of a vehicle. A visual inspection involves examining various components of the vehicle to identify any visible wear, damage, or malfunction.

Inspecting brake pads is a clear example of a visual inspection because it requires the inspector to look at the condition of the pads themselves. This process allows the driver or mechanic to see whether the pads are worn down or if there are any visible signs of damage, such as cracking or uneven wear, that could indicate safety issues.

In contrast, listening for unusual noises typically involves audio assessment, not a visual check. Using a computer diagnostic tool assesses system functionality through electronic means rather than visual observation. Checking tire pressure with a gauge, while critical, is primarily a measurement action rather than a direct visual inspection of the condition of the tires themselves.
