How should the windshield be inspected?

The proper inspection of a windshield is critical for ensuring driver and passenger safety. The primary focus is on visibility, which is why the correct response highlights that the windshield must be free of significant cracks and chips that impair visibility. Any impairment to visibility can increase the risk of accidents, as it obstructs the driver's view of the road and surroundings. Therefore, during the inspection, the inspector checks for any damages that might compromise seeing the roadway clearly.

While the replacement of a damaged windshield may be necessary in cases where significant impairments are found, the option that specifically addresses the requirement for safety is that it must be clear for optimal visibility. Additionally, while features like UV protection and functioning windshield wipers contribute to overall vehicle safety and comfort, they are not the primary focus of the windshield's visual inspection under standard safety inspections.
