When a bus is required to stop at railroad tracks, what is the farthest it may stop from the nearest rail?
Correct answer: B – 50 feet
Federal regulations require a bus transporting passengers to stop within 50 feet of the railroad tracks and no closer than 15 feet. The driver must then look and listen for an approaching train. This range provides a defined stopping position while allowing the driver to evaluate the crossing before proceeding.
