What conditions can lead to a vehicle's windshield failing inspection?

The reason a vehicle's windshield can lead to failing inspection due to cracks, chips, or impairments in the driver's line of sight stems from safety regulations that prioritize visibility. A clear view of the road is crucial for safe driving, and any obstruction or damage that interferes with the driver’s ability to see can significantly increase the risk of accidents. Therefore, any damage that distorts the driver's line of sight is deemed unacceptable during an inspection.

In contrast, while multiple layers of tinting might affect visibility, the assessment often focuses on legality and specific regulations regarding tint darkness. Stickers and decals, although they can sometimes obstruct view, might not be considered significant enough to cause a failure unless they block important visibility areas. Lastly, excessive dirt or grime does impair visibility but can typically be rectified through cleaning, which might not warrant a failure in the stance of the inspector if it is easily removable.
