What does this traffic sign combination indicate?

The traffic sign combination you see indicates that you are approaching a level crossing for rail traffic. The first sign warns of the crossing and the presence of trains, while the second sign sets a maximum speed limit of 10 km/h when approaching or crossing this area.

Understanding this combination is crucial for safety. The warning sign alerts drivers to keep a lookout for trains, and the speed limit ensures that drivers can stop safely if necessary since trains can come at any time and are often faster than they appear.

In summary, it's essential to adhere to both signs — to be cautious of potential rail traffic and to comply with the specified speed limit for safe navigation through the crossing.
