What is required for the windshield during a pre-trip inspection?

For a pre-trip inspection, ensuring that the windshield is clean and free of obstruction is crucial for safe operation of the vehicle. A clean windshield allows for optimal visibility, which is essential for the driver to adequately see the road, other vehicles, and any potential hazards. Any dirt, grime, or obstructions such as stickers or objects can impair visibility, leading to increased risk of accidents.

Additionally, if there are any cracks or breaks in the windshield, these can further obstruct the driver’s view and may compromise the vehicle's structural integrity in the event of an accident. Therefore, maintaining a clean and unobstructed windshield is not only a safety requirement but also a legal one in many jurisdictions.

The other options, such as tinting, having a special coating, or allowing cracks or breaks, do not align with safety standards for vehicle operation. In fact, having a tinted windshield or one with any form of impairment would not meet the necessary safety requirements.
