What is the appropriate action when approaching a railroad crossing with flashing lights?

When approaching a railroad crossing with flashing lights, the appropriate action is to stop and wait for the train to pass. The flashing lights are a clear signal that a train is either approaching the crossing or is already in the vicinity. This safety feature is designed to alert drivers and pedestrians of the imminent danger, as trains can come at high speeds and often cannot stop quickly. By stopping, you ensure your safety and the safety of others, because failing to do so could lead to a serious accident.

The other options do not comply with safety protocols. Speeding up to cross quickly increases the risk of a collision, as trains may be closer than they appear and can travel at significant speeds. Honking your horn and proceeding disregards the warning signals indicating danger. Lastly, while it is good practice to look for other vehicles before crossing, the priority must be to heed the flashing lights and ensure the track is clear of any trains before attempting to proceed.
