When are you obliged to stop before a railway crossing?

1. When a “railway crossing” sign is placed.
2. When a “right of way for crossing traffic” sign is placed.
3. You don’t have to stop. Stop at your own discretion when a train is seen and is approaching.
4. Correct answer: When the train is seen, heard or sounds a warning signal.

WhyYou must stop before the crossing if you see or hear a train or its warning signal. It is not up to the driver.
