Final answer:
It is true that drivers should look, listen, and slow down when approaching a railroad crossing without warning signals to ensure safety for themselves and pedestrians.
Step-by-step explanation:
When approaching a railroad crossing that has no warning signals, such as electric flashing lights or gates, it is true that a driver should look, listen, and slow down. Without warning signals, drivers need to be extra cautious to avoid potential hazards at crossings. Railroad crossings can be unpredictable and present a serious risk if not approached with care due to speeding vehicles, pedestrian safety issues, and occasional equipment malfunction.
To ensure safety, drivers need to reduce speed to have adequate time to observe and stop if a train is coming. Looking both ways and listening for a train are essential because the sound of a train can sometimes be detected even if the visual cue is not evident. This is crucial for preventing accidents and ensuring that all road users, including pedestrians, are safe at crossings that lack active warning systems.
