Final answer:
Passive highway-rail crossings require extra caution because there are no active warnings. Drivers and pedestrians must use their own judgment to determine if a train is approaching. Being aware of the dangers and taking precautions is crucial.
Step-by-step explanation:
At passive highway-rail crossings, cautions should be taken because there are no flashing lights, bells, or barriers to signal an approaching train. This means that drivers and pedestrians must rely solely on their own vision and judgment to determine if a train is coming. Due to the absence of active warnings, it is crucial to be extra cautious and never assume that a train is not approaching.
For example, a driver should make sure to look both ways, listen for any train horns or sounds, and cross the tracks only when it is safe to do so. Pedestrians should also look both ways, avoid distractions like headphones or mobile phones, and cross the tracks quickly and directly.
Being aware of the potential dangers at passive highway-rail crossings and taking the necessary precautions can help prevent accidents and ensure everyone's safety.
