When is a bus prohibited from crossing a railroad?

1. When there is a “level crossing” warning sign.
2. Correct answer: When there is no asphalt or cement road that leads to the level crossing, at a distance of at least 20 meters before the nearest track.
3. When a “stop” sign is placed before the tracks.
4. When a “right of way” sign is placed before the tracks.

WhyA bus may not cross railway tracks if the road leading to the crossing is not asphalt or concrete for at least 20 meters before the nearest track. Without a hard surface a heavy vehicle may get stuck on the tracks.
