Which of the following indicates an issue with the windshield during inspection?

A small crack in the windshield is a clear indication of a potential issue during a pre-trip inspection. The integrity of the windshield is crucial for driver visibility and safety. Any crack, regardless of its size, can distort the view of the road, potentially impairing the driver's ability to see other vehicles, pedestrians, or road signs clearly. Additionally, a crack could worsen over time due to environmental factors or stress, leading to further visibility hazards.

In contrast, a clean and clear windshield suggests optimal visibility, which is ideal during driving. A securely mounted windshield indicates that the windshield is well installed and minimizes the risk of it dislodging during operation. Having no illegal stickers ensures that the driver's view is not obstructed by any unnecessary objects, which is also important for safe driving. However, these aspects do not indicate any problems with the windshield itself, making the presence of a crack a significant concern to address during the inspection.
