In this situation, do you have the right to overtake the vehicle on the right?

In the video you are driving in a town on a single-lane slip road leading onto a flyover, behind a brown car; the roadway is narrow, bounded by a kerb and a barrier, without marked lanes. You do not have the right to overtake the car on the right. The answer is: no.

The Road Traffic Act requires you to overtake on the left and allows overtaking on the right only on a section of road with marked lanes - on a one-way roadway or on a two-way roadway with the appropriate number of lanes in one direction - and only when the general conditions are met: adequate visibility and enough space to overtake without obstructing anyone. The slip road in the video has one lane, without lines marking lanes, and to the right of the car there is only a kerb and a barrier - there is neither a legal basis nor physical space for such a manoeuvre. Overtaking on the right outside the roadway is a serious traffic offence and a real risk of scraping the barrier or hitting a pedestrian. So you follow the brown car, keeping your distance, until the end of the slip road, where the road widens into several lanes - only there, if there is a need and a possibility, may you overtake it.

Legal basis: Art. 24 para. 3, para. 10 and para. 1 point 1 of the Road Traffic Act (Prawo o ruchu drogowym)
