In addition to stopping at a railroad crossing, what must a driver do?

When approaching a railroad crossing, it is essential for a driver to look and listen to ensure that the tracks are clear. This action is critical because it helps the driver assess whether a train is approaching the crossing. Unlike regular road scenarios, railroad crossings can present unexpected dangers, and trains can come at high speeds. By looking both ways and listening for any auditory signals, such as train horns, the driver can make a responsible and informed decision on whether it is safe to proceed.

Turning off the engine, opening the window, or checking the mirrors, while good practices in other driving situations, are not specifically required actions at a railroad crossing. They do not directly contribute to determining the safety of crossing the tracks. Thus, looking and listening is the most important and relevant action to ensure the driver's safety and the safety of others when approaching railroad crossings.
