How should the inspector assess a vehicle's windshield?

Assessing a vehicle's windshield is critical for safety, as it is directly linked to the driver's visibility and overall driving performance. The correct approach involves checking for cracks or obstructions that may impair the driver's view. These defects can significantly hinder the driver's ability to see the road and surrounding environment clearly, increasing the risk of accidents.

A cracked windshield can distort the driver’s view, while obstructions, such as stickers or dirt, may also block the driver’s line of sight. Therefore, ensuring that the windshield is intact and free from anything that could obstruct visibility is paramount. This evaluation is essential in maintaining road safety standards as outlined in Pennsylvania's safety inspection regulations.

While these other aspects, such as scratches, discoloration, outdated stickers, and cleanliness, may be important for overall vehicle aesthetics and maintenance, they do not directly impact the driver's view in the same crucial way that cracks or obstructions do. Thus, while such checks are useful, focusing specifically on the condition of the windshield concerning visibility is the primary concern during an inspection.
