Define level crossing:
- A place where a road and a railroad meet on a freeway.
- A place where a road and a railroad meet at different levels.
- Correct answer: A place where a road and a railroad meet or cross at the same level.
- Any place where a railroad can be crossed
Why this is the answer
The correct answer in the official bank: A place where a road and a railroad meet or cross at the same level.
A level crossing is where a road and a railroad meet or cross at the same level, so road vehicles and trains can be at the same spot. That is why it calls for extra caution. A bridge or tunnel, where the road and the railroad are at different levels, is not a level crossing, because vehicles never share the track with trains there.
