In this situation, are you obliged to continue driving in the right lane?

In the video you are driving in the right lane of a dual carriageway with two lanes in your direction, next to which, on the right, there are signs D-3 and B-33 "60"; the left lane is empty, and one car is driving far ahead of you. In this situation you are required to continue driving in the right lane. The answer is: yes.

The Road Traffic Act requires a driver to drive as close as possible to the right-hand edge of the roadway and, if lanes are marked, to occupy only one of them. Since the right lane is free and you are not overtaking, you have no reason to move to the left one. The left lane is for overtaking: you move into it when you catch up with a slower vehicle, and after overtaking you return to the right one. Thanks to this, faster drivers can overtake you without weaving between lanes, and traffic on the road is smooth and predictable.
