How far should a school bus stop from railroad tracks if no stop line is marked?

When approaching railroad tracks, safety is paramount, especially for school buses that are transporting children. The correct guideline specifies that a school bus should stop no closer than 15 feet and no further than 50 feet from the tracks if no stop line is marked. This distance is critical because it allows the driver to have a clear view of any approaching trains while maintaining a safe buffer zone.

Stopping within the specified range helps ensure that the bus is close enough to see and hear trains effectively while being far enough away to avoid any potential danger from a train that might be passing. Additionally, this distance provides ample space to make necessary decisions and maintain safety for the passengers on board.

The guidelines aim to promote awareness and caution among school bus drivers regarding train traffic, which is particularly relevant in areas where railroads intersect with roadways.
