If the warning lights are flashing but no train is approaching, what is the best action?

The appropriate action when the warning lights are flashing but no train is approaching is to not move and report to your supervisor. This response is crucial because the flashing lights indicate a potential hazard, suggesting that a train could be coming, or that there is a fault with the warning system. Remaining stationary ensures the safety of the students on board, allowing for a proper assessment of the situation.

Additionally, it's important to report to a supervisor so the issue can be addressed. This could involve notifying the relevant authorities about the malfunction of the warning signals. Ensuring communication with the appropriate personnel is essential in maintaining safety protocols and preventing possible accidents.

Proceeding cautiously across the tracks or backing up could pose risks to students and drivers, particularly since the lights could indicate an imminent danger. Evacuating students is also unnecessary in this scenario unless there is an immediate threat, which is not indicated merely by the flashing lights. Thus, the recommended course of action is to stay put and communicate the situation to ensure everyone remains safe.
