What is the meaning of the information sign shown in the image?

Question

DentroTest · Accepted Answer

The sign shown is S-11a, “One-way two-lane carriageway”: it indicates that on the two-lane roadway that extends in the direction of the arrows, vehicles must travel in the direction they indicate, and that traveling in the opposite direction is prohibited. Thinking that it recommends traveling in parallel is a mistake: that is not its function. And thinking that it requires you to continue straight ahead without being able to change lanes is one too: it is not a mandatory sign (R-400 series) and does not restrict the lane changes that are permitted.
