What should the condition of the mirror be during inspection?

The correct answer emphasizes that during a pre-trip inspection, the mirrors of the vehicle should be clean and devoid of any illegal stickers. This condition is vital for ensuring the driver has an unobstructed and clear view of the surrounding areas, which is essential for safe driving and maneuvering. Any dirt, obstructions, or illegitimate items on the mirrors could significantly impair visibility, leading to potential hazards on the road. Furthermore, maintaining mirrors in optimal condition reflects the overall standard of vehicle care and safety compliance expected in professional driving environments.

In contrast, the other options either describe conditions that are unacceptable for safe driving—such as cracked or broken mirrors, which would render them ineffective—or indicate that the mirrors are not in a proper condition, such as being scratched but functional or dirty but only partially visible, compromising safety. Therefore, the emphasis on a clean and legally compliant state for the mirrors is essential to ensure maximum visibility and safety on the road.
