On this road, once you go past this sign, can you overtake the vehicle you see on the left?

On the visible roadway with two lanes for one direction, the lanes are separated by a broken line, which allows for a lane change to overtake. The D-8 sign with a "1000 m" plaque only informs about the end of the expressway in one kilometre and does not introduce an overtaking ban at this point. In the absence of B-25 no-overtaking signs, you have the right to perform this manoeuvre, while exercising extreme caution in accordance with Art. 24 para. 3.
