What is the recommended procedure when approaching a railroad crossing?

The recommended procedure when approaching a railroad crossing involves looking first to your left, then to your right, and then left again to ensure you have a clear view of any oncoming trains. This method allows drivers to thoroughly scan both directions for trains that may not be immediately visible.

By checking from left to right, you cover all angles before proceeding, which is essential since trains can be much faster than they appear and may approach unexpectedly. This practice significantly enhances safety as it ensures that drivers are fully aware of their surroundings before entering the crossing.

The other options suggest either incomplete checks or ineffective actions. For example, only looking to the right neglects the potential for a train coming from the left side, and flashing headlights does not effectively communicate with trains. Coming to a stop and listening for train sounds may not be adequate either, as trains can be very quiet at certain distances, and it's crucial to visually verify that the tracks are clear before proceeding.
