Which of the following describes a visibility-related pre-operation check?

• A. Check mirrors, lights, and horn.
• B. Ignore mirrors until later
• C. Check the engine oil only
• D. Check the battery color

Answer: (A)

Visibility before operating means making sure you can see clearly and that others can see you. Checking mirrors, lights, and the horn is exactly about that. Mirrors give you a full view around the loader, lights ensure you can see and be seen in low light or at night, and the horn lets you alert nearby workers or pedestrians to your presence. When these are all working and properly adjusted, you can spot hazards early and communicate your intentions, which is the core safety goal of a visibility-related pre-operation check.

Ignoring mirrors removes critical sight lines, which is dangerous. Checking engine oil or other mechanical items focuses on machine condition, not visibility. Battery color has no relevance to visibility at all.
