It provides information about nearby gas stations

It serves as an advance warning for the railroad crossing

A round black on yellow sign at a railroad crossing serves as an advance warning for the railroad crossing. This type of signage is specifically designed to alert drivers that they are approaching a railroad track where trains may be present. The round shape of the sign signifies a warning, a common practice in traffic control signage, and the yellow color indicates caution, thereby enhancing visibility and drawing attention to the potential hazard ahead.

In this context, the advance warning is crucial for safety, allowing drivers to prepare to stop in case a train is coming. Drivers can then make informed decisions about whether to proceed or halt based on the upcoming crossing. Understanding this warning helps prevent accidents, as railroad crossings can be dangerous if proper caution is not taken.
