What must a bus driver do at a railroad crossing, even when no train is in sight?

Bus drivers must approach every railroad crossing prepared to stop, slowing and looking and listening in both directions before crossing, even when there are no gates, lights, or train in sight. Many crossings require buses to stop; the driver must know and follow state and company rules. The bus should cross only when there is enough room to clear the tracks completely on the far side without stopping. Never shift gears while on the tracks. Because a bus carries many people and accelerates slowly, getting caught on a crossing is among the most dangerous situations a driver can face.
