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

You answered correctly! The figure "26" in the circle on this motorway exit sign indicates the Autobahn exit number 26. In Germany, motorway exits are numbered sequentially, and this helps drivers identify and navigate to specific exits. Remember, the number in the circle on such signs always refers to the exit number, not to the road number or distance. This helps you quickly find your exit on the motorway and follow directions accurately.
