How many times should a driver look and listen before crossing at railroad tracks?

A driver should look and listen twice before crossing at railroad tracks to ensure that it is safe to proceed. This practice is crucial for safety, as it allows the driver to fully assess the situation at the crossing. The first look and listen provides an opportunity to spot any approaching trains or identify auditory signals, such as locomotive horns, indicating a train is on the way. The second look and listen gives the driver an additional chance to confirm that the tracks are clear and that no trains are approaching from either direction. This twofold approach helps mitigate the risk of collisions, as trains can come unexpectedly and often travel faster than anticipated. Being vigilant at railroad crossings is essential for ensuring the safety of everyone involved, including passengers on the bus.
