What does the figure "26" indicate in this traffic sign?

The figure "26" in this traffic sign indicates the exit number on the Autobahn (highway). In Germany, Autobahn exits are numbered sequentially, and this helps drivers identify and prepare for their intended exit. The sign here shows exit number 26, which is 1000 meters away and leads to Düsseldorf-Benrath. It does not represent the Autobahn number (such as A26) nor the distance to Düsseldorf-Benrath. Recognizing exit numbers on signs is important for navigation and safety on German highways.
