What is the minimum distance a bus must stop from a railroad track?

The correct answer reflects the minimum safety distance required for a bus to stop from a railroad track, which is crucial for ensuring passenger safety and preventing accidents. The standard regulation mandates that buses must stop at least 15 feet from the nearest rail. This distance allows the bus operator to maintain visibility of train movements, provides adequate space to react in case a train is approaching, and enforces a safe margin when boarding or alighting passengers near the tracks.

In contrast, the other distances provided do not align with the established safety regulations and guidelines for stopping distances for buses at railroad crossings. Understanding the importance of this minimum distance not only reinforces legal compliance but also enhances operational safety for bus drivers and passengers alike.
