What should you do if you notice a dangerous situation at a railroad crossing?

If you notice a dangerous situation at a railroad crossing, the appropriate action is to look for a blue emergency notification system sign and alert the railroad. This sign provides a phone number to call for emergencies and includes a specific identification number for that crossing, which helps railroad operators respond quickly to the situation. Taking this action ensures that the potential danger is communicated effectively to those who can take necessary precautions or actions to prevent accidents, thus prioritizing safety for all road users.

Other options, such as proceeding cautiously, calling a friend, or waiting for the situation to resolve, do not address the immediate danger and can lead to severe consequences, including accidents or injuries.
