You approach an intersection with a marked stop line. The traffic signal shows a circular red light. There is no green arrow permitting your movement and no police officer directing you to proceed. What must you do?

Do not cross the stop line on red in the stated circumstances. A permitted green directional arrow or a police officer’s direction is a different situation; even with permission to proceed, check that the way is safe.

在题设条件下，红灯时不能越过停止线。允许通行的绿色方向箭头或警察指挥属于不同情形；即使获准通行，也要确认前方安全。
