What must you do if you hear a train horn while driving near train tracks?

When you hear a train horn while driving near train tracks, the appropriate response is to stop, look, and listen for an approaching train. This action is crucial for your safety and the safety of others. The train horn serves as a warning that a train may be nearby, and it's essential to be vigilant before proceeding.

Stopping allows you to assess the situation carefully. Looking means checking both directions along the tracks to ensure no train is approaching. Listening is equally important, as trains can sometimes be closer than they appear and can be difficult to see, especially in certain weather conditions or at night. This combination of actions helps prevent collisions, which can have fatal consequences.

The other options may lead to dangerous situations. Speeding through the crossing could result in a catastrophic accident if a train is indeed coming. Ignoring the horn is risky, as the sound is a clear alert to potential danger. Proceeding as usual without taking precautions would mean disregarding the warning signal and increase the likelihood of an accident.
