What should be confirmed about the windshield?

The windshield is a critical component of a vehicle that directly impacts visibility and safety. For safe operation, it is essential that the windshield is clear of any illegal stickers or obstructions. This ensures that the driver has an unobstructed view of the road and surroundings, reducing the risk of accidents.

Illegal stickers can vary by jurisdiction, but they often include items that are not permitted to be displayed on windshields, such as certain types of advertising or promotional materials. Additionally, any obstructions, such as cracks, dirt, or other items, can impair the driver's ability to see clearly, which is crucial for safe driving. Therefore, confirming that the windshield is free from these issues is a vital step in the pre-trip inspection process.

The other options, while they may relate to personal preferences or aesthetic choices, do not address the fundamental requirement for safety and functionality that a clear windshield provides.
