På dansk Anbefalet hastighed

What it means
The road is unsuitable for a higher speed than shown. The recommendation lasts until E40 or the distance stated on a plate.
Your action
Use the figure as guidance for the road and go slower when visibility, grip or traffic requires; also obey any applicable legal speed limit.
Common mistake
This square blue sign is neither a mandatory minimum nor the red-bordered C55 maximum-speed sign.
