How far away from the crossing tracks should the bus come to a stop?

When approaching railroad crossing tracks, school buses are required to stop between 15 and 50 feet before the crossing. This is mandated to ensure that the bus driver has adequate visibility of the tracks and any oncoming trains, enabling them to make a safe decision about whether it's safe to proceed. Stopping at least 15 feet away helps maintain a safe distance while still allowing the driver to check for trains effectively. The upper limit of 50 feet ensures that the bus does not obstruct traffic while still being cautious enough to prevent any potential accidents with trains. This balance between safety and practicality is vital for the safety of the students on board and other road users.
