When stopping the bus at railroad crossings, what is a necessary step regarding the gears?

When stopping the bus at railroad crossings, it is necessary to shift into neutral. This action is important because it ensures that the bus is not under power while stopped, which allows for greater control and prevents any accidental acceleration. Shifting into neutral disengages the transmission from the engine, ensuring that if the bus were to roll, it wouldn’t do so under its own power. It also enables the driver to focus on the critical task of observing for trains without the distraction of managing the vehicle's movement.

In this context, shifting into park would not allow for rolling, but would prevent the driver from accelerating if needed after stopping to cross safely. Shifting into reverse or drive does not apply in this situation either, as the focus should be on effectively stopping and surveying the area for any incoming trains rather than maneuvering the bus forward or backward. The primary goal at a railroad crossing is to prioritize safety by ensuring all precautions are taken, including properly positioning the bus in neutral to enhance safety and control.
