✓

Correct!

Correct. The manual states the overhead strobe light should be used when the driver has limited visibility, meaning they cannot easily see around the bus, in front, behind, or beside it, and that drivers must follow their state or local regulations on using these lights.

✗

Not quite.

Wrong. The manual ties strobe light use to limited-visibility conditions, not to constant use whenever the bus is moving.

The correct answer is A: When visibility is limited, meaning the driver cannot easily see in front of, behind, or beside the bus, subject to applicable state or local regulations.

✗

Not quite.

Wrong. The trigger is limited visibility, which can occur at any time of day such as fog or heavy precipitation, not a fixed nighttime schedule.

The correct answer is A: When visibility is limited, meaning the driver cannot easily see in front of, behind, or beside the bus, subject to applicable state or local regulations.

✗

Not quite.

Wrong. Strobe light use is tied to visibility conditions while driving, not to the loading/unloading process, which is governed by separate stop-arm and warning-light rules.

The correct answer is A: When visibility is limited, meaning the driver cannot easily see in front of, behind, or beside the bus, subject to applicable state or local regulations.
