What do you have to be aware of when you see this traffic sign combination?

The traffic sign you see indicates a rail crossing, which signals that a railway line is nearby. The sign, along with the striped post, informs drivers of the distance to the rail crossing. In this case, the specific meanings are:

1. The sign warns that you are approaching a rail crossing at a distance of 240 meters.
2. The striped post reinforces the caution required and indicates that no overtaking is permitted in this area to ensure safety.

Understanding these signals is crucial for ensuring safety when driving near rail crossings, as trains may approach without much notice. Being aware of these signs helps prevent accidents and ensures compliance with road rules.
