How the test asks about it
- 1.
What does this white X-shaped sign at a railway line mean?
Not quiteCorrect answer: D — Yield to any train; stop if a train is approaching
The crossbuck is a yield sign for railway crossings. Slow down, look and listen, and be ready to stop. A train needs more than a kilometre to stop — it can never yield to you.
A crossbuck does not require a stop every time, but buses and vehicles carrying hazardous materials must stop at every crossing.
- 2.
You reach this sign at a set of tracks with no gate, no lights and no train in sight. What is your obligation?
Not quiteCorrect answer: D — Yield — slow, look and listen, and stop if a train is coming
The crossbuck is a yield sign. It does not require a stop when the way is clear, but it does require you to slow, look both ways and be prepared to stop.
A dark crossing is not a safe crossing. The crossbuck carries the yield obligation on its own, without any lights.
