Are vehicles performing regular transportation of passengers on all roads allowed to occupy the leftmost lane of a road that has 3 or more lanes in one direction?

Explication

Regular passenger-service vehicles are restricted from occupying the far-left lane on roads with at least three same-direction lanes, except to position for a left turn or a U-turn. Using that lane merely to overtake, or remaining there without the specified manoeuvre, falls outside the exception.
