If a train crossing gate comes down as a bus approaches, what should the driver do?

When a train crossing gate comes down as a school bus approaches, safety is the primary concern. The recommended action in this situation is to stop immediately and wait until it is safe to proceed. The correct response emphasizes that the bus driver must adhere to safety protocols established to prevent accidents.

If the driver were to consider driving through the gate, it could lead to a hazardous situation, potentially placing passengers and others in danger if a train is approaching. Staying put ensures that the bus is clear of the tracks and allows the gate to serve its purpose of preventing cross-traffic during a train's arrival. The other options, such as backing up or calling the police, do not address the immediate need for safety in the vicinity of the crossing. By halting at the crossing and waiting, the driver also allows any necessary emergency procedures to be enacted if a train is present.
