When crossing railroad tracks, how many feet should you add to the length of the school bus for containment?

When approaching a railroad crossing, it's crucial for a school bus driver to account for the entire length of the vehicle, including any added space for safety. The recommendation to add 15 feet to the bus's length relates to ensuring there is enough distance for the bus to clear the crossing completely after it passes over the tracks.

This additional length provides a buffer zone that takes into consideration both the bus's actual size and the need to be well away from the tracks as a precaution against any potential hazards, such as an approaching train. The added distance helps ensure that the bus does not inadvertently position itself dangerously close to the tracks during the crossing, which is especially important for the safety of the students onboard.

In summary, the recommended 15 feet serves as a safety margin to enhance awareness and prevent accidents while crossing railroad tracks.
