In this situation, are you allowed to overtake the vehicle shown from the right side?

In the video you are driving in the right lane of one roadway of a dual-carriageway street in town, separated from the roadway for the opposite direction by a strip of greenery, and on the right there is sign D-3 "one-way road"; a silver car is driving ahead of you in the left lane. You are allowed to overtake it on the right - you are driving on a one-way roadway with marked lanes. The answer is: yes.

The Road Traffic Act allows overtaking on the right on a section of road with marked lanes on a one-way roadway, and on a two-way roadway if at least two lanes in a built-up area, or three outside it, are intended for traffic in the same direction; the general conditions for overtaking still apply. Sign D-3 confirms that you are driving on a roadway where traffic moves in one direction. When overtaking on the right, you exercise particular caution and keep your distance, you do not drive onto the shoulder or into a bus lane, and you stay alert, because the driver on your left may not expect a vehicle on that side.
