How should you react when approaching a railway crossing with no lights or gates?

When approaching a railway crossing with no lights or gates, it is crucial to prioritize safety. Stopping at the crossing allows you to listen and look for any oncoming trains. Trains can come unexpectedly, and they often travel at high speeds, making them difficult to see or hear until it’s too late if you're moving quickly. By stopping, looking both ways, and then proceeding with caution, you ensure that the track is clear before crossing.

The other options do not adequately address the need for careful observation and awareness at railway crossings. Speeding up may put you in danger from a surprising train presence. Signaling or honking can be helpful in certain driving situations but doesn't replace the necessity of being vigilant and assessing the environment around the crossing. Thus, stopping, looking both ways, and then moving forward only if it's safe is the safest and recommended approach.
