What can be done during the pre-trip inspection to check the visibility of the driver?

Ensuring that mirrors and windows are clean and unobstructed is crucial for the visibility of the driver during a pre-trip inspection. Clear mirrors and windows allow for optimal sightlines, enabling the driver to see road conditions, other vehicles, and potential hazards. This step is essential for maintaining safety, as impaired visibility can lead to accidents or prevent the driver from being aware of their surroundings.

While adjusting the driver's seat to a comfortable position can improve personal comfort and posture, it does not directly relate to visibility in the same way that maintaining clean and unobstructed windows and mirrors does. Similarly, asking another person if they can see the driver clearly may provide anecdotal feedback but does not verify that the driver has adequate visibility for safe operation of the vehicle. Performing a test drive can help assess driving conditions, but it is not a part of the pre-trip inspection specifically aimed at ensuring visibility prior to beginning a journey. Thus, focusing on the cleanliness and unobstructed view of mirrors and windows directly addresses the visibility concerns critical for safe driving.
