Are you allowed in this situation to overtake the vehicle?

In the video you are driving on a two-way roadway which has two lanes in your direction separated by a broken line, and it is separated from the opposite traffic by a double solid line. A red car is driving in the right lane, and the left lane in your direction is free. You may overtake it using the left lane, without entering the part of the roadway for oncoming traffic. The answer is: yes.

The Road Traffic Act tells you, before overtaking, to make sure that you have suitable visibility and enough space, that no one behind you has started to overtake you, and that the vehicle in front is not signalling a change of lane; you carry out the manoeuvre itself on the left with particular caution. The double solid line is not a problem, because you do not cross it - the whole manoeuvre fits within the lanes of your direction.

Legal basis: Art. 24 para. 1-3 of the Road Traffic Act (Prawo o ruchu drogowym); § 86 para. 5 of the Regulation on road signs and signals
