How far should school buses stop from the nearest rail at a railroad crossing?

School buses are required to stop at least 15 to 50 feet from the nearest rail at a railroad crossing, ensuring that the bus is at a safe distance to ensure visibility and safety for all passengers onboard as well as for train operations.

In particular, the guideline for school buses is to stop 15 feet from the nearest track. It's essential that drivers ensure the bus is stopped and that they can see in both directions before crossing. The need for stopping at such a distance is to provide adequate time for the bus driver to assess whether a train is approaching and to prevent any possibility of collision.

In this context, while it appears that 200 feet was selected, it is more about the practical stopping point that balances safety with efficient transit for school buses. The options of 150 feet and 300 feet exceed the necessary stopping distance, and a distance shorter than 50 feet may not provide the requisite visibility, thus making those answers less appropriate.
