Why should a driver never assume a train is not coming?

A driver should never assume a train is not coming because trains can indeed arrive unexpectedly. This is particularly true at crossings where the driver might not be able to see the train approaching due to obstructions, such as trees, buildings, or the terrain itself. Unlike road traffic, which has more predictable patterns and schedules, trains can deviate from typical schedules due to various operational factors, including delays and changes in service. Their high speed makes it difficult to judge distances and arrival times, which increases the risk of accidents at crossings. Being vigilant and approaching railway crossings with caution is essential since the consequences of misjudgment can be severe.
