Which action is required when approaching a train track with an active warning signal?

When approaching a train track that has an active warning signal, the required action is to prepare to stop. Active warning signals, such as flashing lights or crossing gates, indicate that a train is approaching and that it is essential for all vehicles, including school buses, to halt and ensure safety. Failing to stop can lead to dangerous situations, including collisions with trains, which can have catastrophic consequences.

Preparing to stop allows the driver to assess the situation, ensuring it is safe to proceed only after the signals have stopped and no train is approaching. It is crucial to recognize that these signals are in place to protect both vehicle occupants and train passengers, highlighting the importance of a cautious and respectful approach to railway crossings.
