At a railway level crossing, you must not cross when

• A. The green light shows or alarm sounding
• B. The red light shows
• C. The red light shows or alarm sounding
• D. The barriers are down

Answer: (C)

At level crossings, signals are there to tell you when it’s safe to cross and when it isn’t. The crucial rule is to avoid crossing when danger signals are active. A red light means you must stop immediately and not cross until it’s safe again. If the alarm is sounding, danger is imminent, so crossing is not permitted. Barriers down indicate you should not cross, but that situation is effectively signaled by the red light or the alarm, which are the direct triggers to stop. Green light means you may cross, provided there are no other hazards. So the best rule to remember is you must not cross when the red light shows or the alarm is sounding.
