You should rely only on watchman, gates or automatic warning devices when approaching railroad crossings.

When approaching railroad crossings, it's crucial not to rely solely on watchmen, gates, or automatic warning devices. These aids are important for alerting drivers to the presence of trains, but they can sometimes fail due to mechanical issues, human error, or unforeseen circumstances. Therefore, drivers should actively look and listen for trains while approaching any railroad crossing, regardless of the presence of such warning devices.

By taking personal responsibility for safety and being vigilant in scanning the tracks and listening for train sounds, drivers can make better-informed decisions. This proactive approach enhances safety and helps prevent accidents, as conditions may change unpredictably. Hence, it's essential to remain alert and not depend entirely on external signals or devices when navigating through railroad crossings.
