What condition must the windshield be in for safety?

For safety, the windshield must be free of cracks and obstructions because it plays a critical role in driver visibility. A clear windshield ensures that the driver can see the road, other vehicles, and pedestrians without interference. Cracks can distort vision, create blind spots, and even worsen over time, potentially leading to a complete failure during driving. Obstructions, such as stickers or foreign materials, can block the driver's line of sight, increasing the risk of accidents. Therefore, maintaining a clear, unobstructed windshield is essential for safe operation of the vehicle.

While having a clean and polished windshield is important for visibility, it does not address the safety issues posed by structural integrity, which is why the second choice is prioritized. Tinted windshields can be legal in certain contexts but are not a safety requirement in themselves. Similarly, a valid inspection sticker is a regulatory compliance issue rather than a direct safety concern regarding visibility.
