You reach the sign shown at a quiet intersection. What does it require even when no traffic is visible?
Correct answer: A complete stop before proceeding when safe.
STOP requires a full stop, not merely a reduction in speed. Use the stop line, or the appropriate crosswalk or intersection stopping position, then yield before proceeding.
