What should you do when approaching a railroad crossing with red flashing lights?

When approaching a railroad crossing with red flashing lights, the appropriate action is to come to a full stop before the tracks. This response is crucial for ensuring safety, as the flashing lights indicate that a train is either approaching or is on the tracks, and proceeding without stopping could lead to a serious collision. Stopping allows drivers to assess the situation, ensuring that no trains are coming before attempting to cross.

Other responses suggest inappropriate actions. Speeding up to cross quickly can result in being caught on the tracks when a train arrives. Looking for a train without stopping can also be dangerous, as trains can come from either direction and are often faster than anticipated. Waiting for a certain amount of time without understanding the context of the crossing might also lead to unnecessary risks. Therefore, stopping fully is the safest and most responsible choice in this situation.
