As long as there is not much traffic, you should choose the lane furthest to the right. The road goes from two to three lanes in the direction of travel. Here there is little traffic, so according to the traffic rules, you should position yourself in the rightmost lane. The right lane is not reserved for heavier vehicles.

Public transport lanes are separated with a separating line, not lane lines as in this task. Exit lanes are not signposted with informative signs, but with marking signs and lane guides as the example below.
